Look at the underlined part of each sentence. Below each sentence are given three possible substitutions for the underlined part. If one of them (a), (b) or (c) is better than the underlined part, indicate your response on the Answer Sheet against the corresponding letter. If none of the substitutions improves the sentence, indicate (d) as your response on the Answer Sheet.

Explanation
Time clauses introduced by 'till' or 'until' take the simple present tense even when referring to the future, giving 'till you reach an island'. Using the future 'will reach' inside the till-clause is a standard error. The main clause 'Go north-east' is an imperative, and the subordinate clause must stay in the present. Thus 'will reach' must be replaced by 'reach', option (b).
