Correct option is E
For blank in the sentence discussing the effects of noise pollution on concentration and mental peace, the most appropriate word is:
(e) impair
"Impair" means to weaken or damage something, which perfectly describes the negative impact of excessive noise pollution on one's ability to concentrate and maintain a peaceful state of mind.
Here's why the other options are not suitable:
· "Recollect" means to remember something, which doesn't pertain to the effect of noise pollution.
· "Absurd" is an adjective describing something extremely unreasonable or foolish, which doesn't fit grammatically or contextually here.
· "Intimidate" means to frighten or overawe someone, which doesn’t directly relate to the subtler impacts on concentration.
· "Spook" generally means to scare or frighten, often suddenly, which isn’t the appropriate term to describe the gradual impact of noise on concentration.
