        "itemId": "map-route-reasoning-s01-q05",
        "explanation": "Unless a map states otherwise, the convention is north at the top, which also puts east on the right and west on the left."

        "explanation": "Track each quarter turn: west → north (90°) → east (180°) → south (270°). Alternatively, 270° clockwise equals 90° anticlockwise."

        "itemId": "map-route-reasoning-s02-q01",

        "itemId": "map-route-reasoning-s02-q04",
        "explanation": "Follow each turn: east → north (left) → west (left) → north (right). A quick check is to net the turns: two lefts and a right equal one left overall."

        "itemId": "map-route-reasoning-s02-q05",
        "explanation": "When a map is turned to match your facing direction, the map's left edge lines up with your own left side, and facing south, your left hand points east."

        "itemId": "map-route-reasoning-s02-q09",
        "explanation": "The northbound walker's right is the east side of the street. Facing south, east falls on your left, so the southbound walker sees the shop on their left."
      },
      {
        "itemId": "map-route-reasoning-s02-q10",
        "explanation": "Work each person separately: your right turn takes north to east, while your friend's right turn takes south to west. East and west are opposites, so you still face away from each other."

        "itemId": "map-route-reasoning-s03-q01",
        "explanation": "Compare the coordinates: only x changes, rising from 2 to 5. An increasing x-value on this grid means movement east."
      },
      {
        "itemId": "map-route-reasoning-s03-q02",
        "explanation": "The x-values match, so the points sit on the same north–south line; subtract the y-values: 6 − 1 = 5 units."

        "itemId": "map-route-reasoning-s03-q04",

        "itemId": "map-route-reasoning-s03-q05",
        "explanation": "Furthest west means the smallest x-value; ignore the y-values entirely. The x-values are −3, 1, 4, and 0, and −3 is the smallest."

        "itemId": "map-route-reasoning-s03-q07",

        "itemId": "map-route-reasoning-s03-q08",
        "explanation": "Net each axis: east 6 then west 2 leaves x = 4, and the single northward leg leaves y = 2, so the drone ends at (4, 2)."

      {
        "itemId": "map-route-reasoning-s03-q09",
        "explanation": "The points are 4 grid squares apart along the same line; multiply by the scale: 4 × 500 m = 2,000 m, which is 2 km."

        "itemId": "map-route-reasoning-s03-q10",
        "explanation": "Corner-only (diagonal) neighbours differ by one step in both the column and the row. B2 shifts one column west and one row south of C3, while the others share a full edge."
      },
      {
        "itemId": "map-route-reasoning-s04-q01",

      },
      {
        "itemId": "map-route-reasoning-s04-q02",
        "explanation": "Opposite directions subtract rather than add: 6 km north minus 2 km south leaves a net 4 km north of the start."

      {
        "itemId": "map-route-reasoning-s04-q03",

        "itemId": "map-route-reasoning-s04-q05",

        "itemId": "map-route-reasoning-s04-q06",

        "itemId": "map-route-reasoning-s04-q08",

        "itemId": "map-route-reasoning-s04-q09",

        "itemId": "map-route-reasoning-s04-q10",
        "explanation": "Net each axis: east 2 and west 2 cancel, while north 1 against south 3 leaves 2 km south. Splitting a route into axes makes multi-leg journeys manageable."
