Can someone explain why answer is three?
Cuz cicle allow light to pass through . Then since triangle same size as square. When an object is nearer to the light source . It wall cat a larger shadow thus blocking out the square

I suppose the human body is at 37c.... environment temp usually don't reach 37c....so if you want to feel cool u need to lose heat to surrounding....so u need fabric Y....but in a cold environment u need fabric X to keep warm

Concept tested here is that heat is transferred from object at higher temperature to object at lower temperature.
Body temperature is 37 deg C while surrounding normally lower. Hence body loses heat to surrounding.

Y is better conductor of heat, hence heat is lost at faster rate through Y.

dear parents, since psle is over, would be super appreciated if you could pm me your recommended teacher / tuition for science. I am a desperate mom of a p4 girl and she told me she was so confused in the OE questions although we have done a lot of school papers and spent plenty of time in analyzing the problems together.

But I feel the efficiency is quite low. We put great efforts but result is not that positive cause I really don't know the tips for the OE questions .
