      },
      {
        "itemId": "memory-retention-s01-q07",
        "explanation": "The list ended with purple. Repeating the final item to yourself once before continuing is a simple way to anchor it."
      },
      {
        "itemId": "memory-retention-s01-q08",
        "explanation": "The detail paired one time with one day: 6 pm on Saturdays. Linking the two together as a single phrase makes the fact easier to hold."
      },
      {
        "itemId": "memory-retention-s01-q09",
        "explanation": "The list held three animals: fox, heron, badger. Counting items as you read gives you a second, independent memory cue."
      },
      {
        "itemId": "memory-retention-s01-q10",
        "explanation": "The bicycle was at stand C. Turning a bare letter into an image, C for 'cycle', makes a single-character detail more memorable."
      },
      {
        "itemId": "memory-retention-s02-q01",
        "explanation": "The appointment was on Tuesday. Days that start with the same sound, like Tuesday and Thursday, are easily confused. Encode the full word, not just its first letter."
      },
      {
        "itemId": "memory-retention-s02-q02",
        "explanation": "The neighbour lives at number 27. Reversed digits like 72 are a classic recall trap: fixing the order at study time prevents the swap."
      },
      {
        "itemId": "memory-retention-s02-q03",
        "explanation": "Henrik is the baker. Binding each name to its role, perhaps imagining Henrik holding a loaf, keeps the pairs from crossing over."
      },
      {
        "itemId": "memory-retention-s02-q04",
        "explanation": "The train leaves from platform 4. When a detail contains several numbers, attach each one to its label (platform 4, time 10:42), rather than remembering loose digits."
      },
      {
        "itemId": "memory-retention-s02-q05",
        "explanation": "The recipe called for 250 g of flour. Saying a quantity with its unit and ingredient as one phrase helps it survive the delay."
      },
      {
        "itemId": "memory-retention-s02-q06",
        "explanation": "The car was in row F. Pairing the two parts into one cue, '3F', halves what you have to hold on to."
      },
      {
        "itemId": "memory-retention-s02-q07",
        "explanation": "The clinic is now on Milton Road. When a fact involves a change, deliberately tag the new value as 'current', old locations and near-misses like Milton Street compete at recall."
      },
      {
        "itemId": "memory-retention-s02-q08",
        "explanation": "The club meets at Lena's flat. A quick mental picture of the host at her door encodes place and person in one image."
      },
      {
        "itemId": "memory-retention-s02-q09",
        "explanation": "Doors open 20 minutes before the 7:50 pm start, so 7:30 pm. Working the answer out at study time, rather than at recall time, stores the result you actually need."
      },
      {
        "itemId": "memory-retention-s02-q10",
        "explanation": "Marcus runs the induction. When a detail lists several facts, sort them into slots (who, where, what to bring), so each can be retrieved on its own."
      },
      {
        "itemId": "memory-retention-s03-q01",
        "explanation": "The order was lamp, mirror, clock, vase, the clock followed the mirror. Rehearsing items in linked pairs preserves order better than rehearsing them singly."
      },
      {
        "itemId": "memory-retention-s03-q02",
        "explanation": "Sam stood last. The ends of a sequence are usually the easiest to keep: the first and final positions act as natural anchors."
      },
      {
        "itemId": "memory-retention-s03-q03",
        "explanation": "Monday was the swim. Treating each day–activity pair as its own mini-fact stops the whole week blurring into one list."
      },
      {
        "itemId": "memory-retention-s03-q04",
        "explanation": "Fern Hill was the third stop. Mentally riding the route, picturing each stop passing the window in turn, encodes position along with place."
      },
      {
        "itemId": "memory-retention-s03-q05",
        "explanation": "Ruby sat third of five: the exact middle. Middle items are the most often lost, so give the centre of a list extra rehearsal."
      },
      {
        "itemId": "memory-retention-s03-q06",
        "explanation": "Ines beat Jack and Jack beat Petra, so Jack was in the middle. Converting relational statements into one ordered line at study time makes recall a simple read-off."
      },
      {
        "itemId": "memory-retention-s03-q07",
        "explanation": "The sequence ended with a hold. Miming a sequence of actions, even faintly, adds a motor memory on top of the verbal one."
      },
      {
        "itemId": "memory-retention-s03-q08",
        "explanation": "June came second in the studied list. Note the trap: the question asks about list position, not calendar order."
      },
      {
        "itemId": "memory-retention-s03-q09",
        "explanation": "Left to right the order was Priya, Owen, Zainab, Leo, so Owen sat on Zainab's left. Sketching the row in your mind's eye turns a word list into a scene you can inspect."
      },
      {
        "itemId": "memory-retention-s03-q10",
        "explanation": "Flashing amber followed red. Familiar patterns tempt you to recall what usually happens instead of what you actually studied, trust the studied sequence."
      },
      {
        "itemId": "memory-retention-s04-q01",
        "explanation": "The sequence ran 4, 7, 2, 9, so the third digit was 2. Reading digits in a steady rhythm gives each one a positional beat you can count back to."
      },
      {
        "itemId": "memory-retention-s04-q02",
        "explanation": "The code was 58-31. Every wrong option here is a transposition of the same digits, the usual way codes are misremembered, so lock the order in, not just the digits."
      },
      {
        "itemId": "memory-retention-s04-q03",
        "explanation": "The sequence ended in 1. Giving the final digit a deliberate extra glance before hiding the material protects the position most easily rushed past."
      },
      {
        "itemId": "memory-retention-s04-q04",
        "explanation": "The reference was TX-4085. Splitting a mixed code into its letter part and number part, then rehearsing each, beats treating it as one opaque token."
      },
      {
        "itemId": "memory-retention-s04-q05",
        "explanation": "The extension 7-3-7-2 contained the digit 7 twice. Noticing repeats while studying compresses the string and gives you a checksum for later."
      },
      {
        "itemId": "memory-retention-s04-q06",
        "explanation": "Bus 19 serves the hospital. Two number–destination pairs are held best as two tiny sentences, not as four separate facts."
      },
      {
        "itemId": "memory-retention-s04-q07",
        "explanation": "The digit 3 appeared three times: first, third, and last. Tallying repeats during study means the count is remembered, not reconstructed."
      },
      {
        "itemId": "memory-retention-s04-q08",
        "explanation": "The code was 2580. The middle column of a phone keypad read top to bottom. Spotting a pattern inside a number gives you a rule to regenerate it from."
      },
      {
        "itemId": "memory-retention-s04-q09",
        "explanation": "The first two digits were 9 and 4, which sum to 13. Recalling stored digits and then operating on them is harder than either task alone: anchor the digits first, then compute."
      },
      {
        "itemId": "memory-retention-s04-q10",
        "explanation": "The seat was 14B, on coach C. Two nearby letters invite blending: attach each letter firmly to its own object before hiding the detail."
      },
      {
        "itemId": "memory-retention-s05-q01",
        "explanation": "Chloe plays the flute. A quick image of each person holding their instrument welds the pair together far better than repeating the words."
      },
      {
        "itemId": "memory-retention-s05-q02",
        "explanation": "Glass goes in the green bin. A sound link, 'green glass' share a starting sound, is a legitimate shortcut worth noticing at study time."
      },
      {
        "itemId": "memory-retention-s05-q03",
        "explanation": "Madrid was paired with the Prado. Testing yourself pair by pair before continuing, covering one side and recalling the other, is the fastest way to secure associations."
      },
      {
        "itemId": "memory-retention-s05-q04",
        "explanation": "Tuesday's password was 'brook'. The passwords ran a, b, c across the days in order, spotting that structure means you only need to remember the rule."
      },
      {
        "itemId": "memory-retention-s05-q05",
        "explanation": "Marco ordered the salad. Beware sound-alike lures: Sana–soup and Priti–pasta alliterate, but Marco–salad does not, and unpatterned pairs need the most rehearsal."
      },
      {
        "itemId": "memory-retention-s05-q06",
        "explanation": "Shelf C held the rope. Walking the shelves in order in your mind (tools, paint, rope) stores the trio as one route rather than three stray facts."
      },
      {
        "itemId": "memory-retention-s05-q07",
        "explanation": "South's code word was 'otter'. A meaning link helps: falcons fly high (north, up on the map) while otters swim low. Invented logic like this is glue for arbitrary pairs."
      },
      {
        "itemId": "memory-retention-s05-q08",
        "explanation": "Lena works the Thursday shift. With three name–day pairs, the middle pair is the most vulnerable. Give it the extra pass."
      },
      {
        "itemId": "memory-retention-s05-q09",
        "explanation": "The pine bench cost £45. Noticing the price order tracks the size order (table, bench, stool from dearest to cheapest) turns three prices into one ranked list."
      },
      {
        "itemId": "memory-retention-s05-q10",
        "explanation": "The maps were in Room 2. Imagining yourself walking room to room and seeing each collection converts numbered pairs into a spatial tour."
      },
      {
        "itemId": "memory-retention-s06-q01",
        "explanation": "Chunking turns twelve arbitrary digits into three meaningful year-sized units, which is far closer to what short-term memory can comfortably hold."
      },
      {
        "itemId": "memory-retention-s06-q02",
        "explanation": "Grouping by category means you recall three small themed lists instead of one long arbitrary one, and each category name acts as a retrieval cue."
      },
      {
        "itemId": "memory-retention-s06-q03",
        "explanation": "Actively retrieving material, with gaps between attempts, strengthens memory far more than passive re-reading. This is the combined power of retrieval practice and spacing."
      },
      {
        "itemId": "memory-retention-s06-q04",
        "explanation": "Routine actions blur together because they are encoded on autopilot; attaching a spoken, time-stamped cue at the moment of action makes that one occasion distinctive and retrievable."
      },
      {
        "itemId": "memory-retention-s06-q05",
        "explanation": "A vivid image that links the new word's sound to its meaning (sol, solar, sun) creates a two-way bridge you can cross in either direction later."
      },
      {
        "itemId": "memory-retention-s06-q06",
        "explanation": "Short-term memory holds a limited number of units, but each unit can be a chunk rather than a single digit, grouping spends that limited capacity far more efficiently."
      },
      {
        "itemId": "memory-retention-s06-q07",
        "explanation": "Placing items along a well-known route, the method of loci, lets a familiar spatial memory carry the new list, and walking the route mentally retrieves every stop."
      },
      {
        "itemId": "memory-retention-s06-q08",
        "explanation": "Spreading the same total effort across spaced sessions produces more durable learning than massing it together, each revisit interrupts forgetting and re-strengthens the trace."
      },
      {
        "itemId": "memory-retention-s06-q09",
        "explanation": "A mnemonic replaces hard-to-order material with an easy, meaningful phrase whose structure silently carries the answer: here, the initial letters give north, east, south, west."
      },
      {
        "itemId": "memory-retention-s06-q10",
        "explanation": "Closing the book and summarising forces retrieval, which both reveals gaps and strengthens what you can recall, a far more active step than re-reading or marking the page."
      },
      {
        "itemId": "memory-retention-s07-q01",
        "explanation": "The notice said the fete moves to the cricket ground. When reading a passage, tag each fact with its question word (where, when, how much), so it files itself under the right cue."
      },
      {
        "itemId": "memory-retention-s07-q02",
        "explanation": "Sofia left from Bay 6. Passages bury small details inside a storyline: noticing the incidental numbers as you read is what makes them recallable later."
      },
      {
        "itemId": "memory-retention-s07-q03",
        "explanation": "The east wing is shut until March. Pinning each fact to its subject (wing: March, hall: open, Sundays: free) keeps a three-fact update from collapsing into a muddle."
      },
      {
        "itemId": "memory-retention-s07-q04",
        "explanation": "The ferns need water every second day. Restating a schedule in your own words ('ferns, alternate days') compresses it into a form that survives the delay."
      },
      {
        "itemId": "memory-retention-s07-q05",
        "explanation": "The restock came at 1 pm. Two times appear in the passage, so each must stay attached to its event: sold out at 9, restocked at 1."
      },
      {
        "itemId": "memory-retention-s07-q06",
        "explanation": "Next week's practice is on Wednesday. When a passage states a change, the old value lingers in memory and competes. Deliberately mark the new day as the one that counts."
      },
      {
        "itemId": "memory-retention-s07-q07",
        "explanation": "The second stop is at the stone bridge. Picturing the walk in sequence (waterfall first, bridge second) stores order and landmark together."
      },
      {
        "itemId": "memory-retention-s07-q08",
        "explanation": "Collection requires photo ID. Practical notices reward a quick self-quiz before moving on: where, until when, and what to bring."
      },
      {
        "itemId": "memory-retention-s07-q09",
        "explanation": "The pool itself reopens on Saturday. The passage gives three different timings for three different things. The question is answered correctly only if each timing stayed with its subject."
      },
      {
        "itemId": "memory-retention-s07-q10",
        "explanation": "The recipe swaps sugar for honey. Substitutions are best encoded as a contrast pair ('honey, not sugar') because the replaced item is exactly what the lure options will offer."
      },
      {
        "itemId": "memory-retention-s08-q01",
        "explanation": "Pear opened both lists. Comparing two lists while both are still visible, actively noting the overlap, is much more reliable than hoping to spot it from memory afterwards."
      },
      {
        "itemId": "memory-retention-s08-q02",
        "explanation": "Ben's meeting is in Room 21. The two bookings mirror each other's digits, which is exactly when facts swap owners, bind each room firmly to its person at study time."
      },
      {
        "itemId": "memory-retention-s08-q03",
        "explanation": "Chalk was only in Box 2, while tape sat in both. Encoding what is unique to each container, rather than the full contents, is the efficient way to study overlapping sets."
      },
      {
        "itemId": "memory-retention-s08-q04",
        "explanation": "The navy folder holds the receipts. When two labels are near-synonyms like blue and navy, lean on a sharper distinguishing cue. Navy is the darker folder, and it holds the receipts."
      },
      {
        "itemId": "memory-retention-s08-q05",
        "explanation": "Code B ran 5, 8, 2. The two codes share the same digits in different orders, so only the sequence separates them: rehearse each code as a rhythm, not a set."
      },

        "itemId": "memory-retention-s08-q06",
        "explanation": "Thursdays are badminton. Two similar-sounding days holding two racquet sports is a recipe for swaps. A link such as 'Thursday has an h, so does shuttlecock... badminton' keeps them apart."

      {
        "itemId": "memory-retention-s08-q07",

        "itemId": "memory-retention-s08-q09",

        "itemId": "memory-retention-s09-q02",
        "explanation": "Ninety minutes after 2 pm is 3:30 pm. Converting 90 minutes to an hour and a half at study time leaves only easy clock arithmetic for later."

        "itemId": "memory-retention-s09-q03",
        "explanation": "Two floors above the third floor is the fifth. Resolving relational facts into absolute ones while the material is visible spares you doing both jobs from memory."

        "itemId": "memory-retention-s09-q04",
        "explanation": "Tomorrow after Sunday is Monday, the one day the market shuts. The item hinges on combining the remembered exception with the remembered day."

        "explanation": "Three full shelves of 12 books each make 36. Holding two quantities and multiplying them is a genuine working-with-memory task, anchor both numbers before you calculate."

        "itemId": "memory-retention-s09-q06",
        "explanation": "The rule was name first, then year: Biscuit2019. Remembering a rule plus its ingredients means the order in the rule matters as much as the parts themselves."

        "itemId": "memory-retention-s09-q07",
        "explanation": "Departures run 8 am, 10 am, 12 pm, so the next after a 9:30 arrival is 10 am. A thirty-minute wait. Generating the timetable from the remembered rule is the key step."

        "itemId": "memory-retention-s09-q08",
        "explanation": "Chaining the two remembered comparisons gives Ravi, Ola, Ben from tallest to shortest, so Ben is shortest. Lining the names up as a single mental ladder does the work."

        "itemId": "memory-retention-s09-q09",
        "explanation": "The first hour costs £2 and the remaining three hours cost £1 each: £2 + £3 = £5. Two-part pricing must be recalled as two parts: flattening it to one rate is the trap."

        "itemId": "memory-retention-s09-q10",
        "explanation": "Two hours before 6:40 pm is 4:40 pm at the airport, and the 30-minute ride pushes the departure back to 4:10 pm. Chaining remembered offsets one at a time keeps the working honest."

        "itemId": "memory-retention-s10-q01",
        "explanation": "The final step after plugging back in was pressing the reset button for 5 seconds. Rehearsing a procedure as numbered steps lets you answer 'what comes after X' by position."

        "itemId": "memory-retention-s10-q02",
        "explanation": "The till is emptied into the safe just before the alarm is set. Recalling a step's neighbours is harder than recalling the step itself. Walk the sequence mentally to the target and read off what precedes it."

        "itemId": "memory-retention-s10-q03",
        "explanation": "Two tablets a day for five days makes 10. The instruction never states the total. You must recall the daily pattern and the duration, then combine them."

      {
        "itemId": "memory-retention-s10-q04",
        "explanation": "The summary is added straight after the photos, with submission last. Five-step procedures sit at the edge of comfortable recall: grouping them into setup, content, and finish helps."

      {
        "itemId": "memory-retention-s10-q06",
        "explanation": "The procedure ends with logging the date. Administrative closing steps are the most commonly dropped from memory because the 'real' task feels finished before them."

        "itemId": "memory-retention-s10-q10",
        "explanation": "The float is £50. In a long procedure, a single embedded figure is easily lost among the actions, giving it a deliberate moment of its own at study time keeps it retrievable."
