Client demo — questions 15–19 all reference the same Ferris wheel diagram (11+ Mathematics, pages 9–10).
These are pages 9 and 10 of the test PDF. Questions 15–19 share a single Ferris wheel diagram. Use the buttons above to compare three possible frontend treatments for this shared image.
Some questions depend on earlier ones — Q16 ("Next time, the two birds fly downwards...") only makes sense if you've read Q15 first. This option includes the prior question as context, with the current question highlighted. Everything is image crops from the source PDF.
Same idea as the image version: Q16 depends on Q15, so both are shown together. Here the diagram is an extracted image and the questions are rendered as HTML text, with the current question highlighted.
15) The compartments are numbered 1–20 in a clockwise direction, with compartment 1 at the lowest point (as shown on the diagram).
Two birds are on top of compartment 11.
From there, one bird flies in a south-east direction and the other bird flies in a south-west direction.
Flying in a straight line, each bird lands on the first compartment it comes to.
On which compartments are the two birds most likely to land?
16) Next time, the two birds fly downwards from the centre of the Ferris wheel at an angle of 35° to the vertical, one in each direction.
On which compartments are the two birds most likely to land?
The diagram is shown once at the top of the set. Questions 15–19 sit below it. Compact and avoids repetition, but the candidate has to scroll back up to the image when answering later questions.

17) Each compartment on the Ferris wheel is painted the same colour as the compartment directly opposite it, i.e. at an angle of 180° to it.
For example, compartments 1 and 11 are both red and no other compartment is red.
If compartment 4 is blue, which other compartment is painted blue?
18) The Ferris wheel starts from the position shown in the diagram and turns until compartment 17 is at the lowest point.
Through how many degrees does the Ferris wheel turn?
19) If the Ferris wheel can make one complete turn in 3 minutes, how many degrees does it turn per second?
Same layout as the "shared diagram, then text questions" option, but each question is a PNG cropped from the source PDF instead of re-typed HTML text. Single diagram at the top, five question-image crops below. Keeps extraction risk low (no OCR / re-typesetting of the question wording) while still only showing the diagram once.
Each question is a self-contained image: the context and diagram cropped from the source PDF are stitched on top of each individual question crop, with all whitespace, headers, footers, and other questions removed. Every question stands alone — no scrolling back — at the cost of repeating the diagram in each image.
Take the relevant regions of the original PDF (diagram + questions) and render them verbatim as image blocks, trimming the page header, footer, and unrelated questions. Preserves the exact source layout — zero re-typesetting risk — but the content is raster, so it can't reflow or be selected as text.
The diagram is shown alongside every question that needs it. No scrolling back, but the page is longer and the same image repeats.

The diagram is hidden by default. A button on each question opens it in a modal. Shortest question list, but adds an extra click for candidates who rely on the image.
