P:For ages that’s what man considered the fly to be –just a nuisance.
Q:It was discovered that these flies carried disease germs that cause the death of millions of people every year.
R:But now we know that the innocent-looking housefly is one of man’s worst enemies.
S:It makes an irritating buzzing sound; it annoys you when it crawls on your skin; and soon.

A) R Q P S B) P Q S R
C) Q P R S D) S P R Q
 
Answer & Explanation Answer: D) S P R Q
