Question

Find the error in the following sentence

Keep him at an arm's length(a) lest you may not repent(b) in the long run.(c) no error(d)

Answer 1

Answer:

(a)keep him at his arms length

(b) atleast you may not repeat

(c)no error

(d)no error

Answer 2

The correct answer is (b) at least you may not repent.  

EXPLANATION:

Keep it at an arm’s length meaning the first person tells that the third person ‘him’ should be kept in a distance otherwise he may hurt the first person in any way.

Therefore the second sentence says ‘at least you may not repent’ meaning ‘so that you will not regret later about the mistake of not keeping him at a distance’. ‘In the long run’ is correct. Repent means feeling bad about the wrong action that is done before .
