Q:

Improve the given sentence if necessary.

Unless you are not very careful, you will run into debt.

A) are very	B) will be very
C) may be	D) No improvement

Answer & Explanation Answer: A) are very

Explanation:

‘Unless’ is used to denote the condition i.e. ‘If’...... ‘Not’. So, again the use of negative word ‘not’ is superfluous. So, the phrase, ‘are not very’ needs to be replaced with ‘are very’ to make the sentence grammatically correct. Thus, the correct formation would be, ‘Unless, you are very careful, you will run into debt’.
