Question

Choose suitable prepositions to complete the following sentence.
I don't understand the reason ___ the increase ___ the fuel prices.

• A. in/of
• B. for/of
• C. off/in
• D. for/in

Answer 1

The correct option is D for/in

Option A - 'In the increase' is incorrect as 'in' means 'inside'. 'Of the fuel prices' is incorrect as 'fuel prices' doesn't own anything. Thus option A is incorrect.

Option B - 'For the increase' is correct as it explains the reason. 'For' is a preposition of purpose. 'Of the fuel prices' is incorrect as 'fuel prices' doesn't own anything. Thus option B is incorrect.

Option C - 'Off' means moving away which is incorrect if used here. 'In the fuel prices' is correct as it explains 'what is the increase in?' Thus option C is incorrect.

Option D - 'For the increase' is correct as it explains the reason. 'For' is a preposition of purpose. 'In the fuel prices' is correct as it explains 'what is the increase in?' Thus option D is the correct answer.

'I don't understand the reason for the increase in the fuel prices.'
