Question

Choose the correct option to replace the word(s) given in brackets:

It is always difficult (climb) a mountain.

• A. climb to
• B. to climb
• C. climbing to
• D. to climbing

Answer 1

Answer: (B)

The infinitive verb is a verb with the word 'to' in front of it. This verb is always just a verb. There is no - ed, no - ing, no - s at the end of the verb. Thus, options A, C and D are wrong according to the rule. The correct option is B since 'to' is in front of the verb 'climb'. Hence, sentence would become: It is always difficult to climb a mountain.
