Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A The blade of Ice-skating shoe is very sharp.
B It is easier to drive a sharp tipped nail into wood.
C Sharp knife cuts better.
D Foundation of high-rise building are kept narrow.

(A) if we decrease the area of the ice skating blades, then we mean to say we are increasing the pressure. We actually do this to increase pressure which reduces the chances of getting slipped.

(B) same concept is applicable in this as it was in the option (a). sharp tipped nail is having less area and therefore exerts more pressure when it is tipped. so it easily gets tipped into the wood or even into the walls.

(C) same concept is in this option as well.

(D) same concept as it was in the previous 3 options.
