Directions: Two sentences marked A and B are given below. Mark your answer as:

(A) if only A is correct (B) if only B is correct (C) if both A and B are correct (D) if both A and B are wrong

(A) If you want to lose weight, eat fewer potatoes. (B) If you wanted to lose weight, eat fewer potatoes.

Sentence A is correct because it uses proper first conditional structure: 'If you want' (present) + 'eat' (imperative). Sentence B is incorrect because it mixes 'wanted' (past) with 'eat' (imperative) - it should be 'If you want to lose weight, eat fewer potatoes' or 'If you wanted to lose weight, you would eat fewer potatoes' (second conditional).
