Has anyone looked at Q29 of Henry Park Science MCQ ? Answer provided is (2) but can't quite understand how that shadow drawn could be possible :?

Hard to explain without diagrams but I shall try.
The light from the torch is a diverging so the shadows form is bigger than the objects.
C is clear glass so no shadow formed.
The black circle is from D which is wood.
There is a circular cut out in D forming the clear area.
The rectangle shadow is from E.

Hope I'm correct.

fyi, the CHS exam papers (for all 4 subjects) in jeremy's set of prelims papers is atually CHS Prelims(1), which is their SA1 (noticed he has erased the dates of the exams and only included the year 2011).. jeremy did not get hold of CHS Prelims(2), which is the recent year-end prelims exam.

Oh, i see.... that explains why 'SA1' is printed.
