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.

Paper 1, question 26 the answer provided is wrong.
Paper 2, question 10, question is incomplete.

Answer for Paper 1 Q26 should be 570 trading cards
Answer for Paper 2 Q10 should be OK if you know that 120 degree is for the \"dogs\".
Q9 from paper 2 is a \"bad\" question. You can get the answer as $15 but when you check backwards, the number of T-shirts is not a whole number. :slapshead:
