A) 1 and 2 only
B) 2 and 3 only
C) 1, 3 and 4 only
D) 2, 3 and 4 only
Correct Answer: D
Solution :
Final size of the balloon after blowing air will depend on initial size, shape and material of the balloon, thus these should be kept same. Colour and design pattern have no effect on it. Breathing in forcibly before blowing will increase the amount of air blowed out hence all of them should breathe in before blowing.You need to login to perform this action.
