Question

Fill in the blank with the most appropriate preposition.

If my car breaks ____________, I'll call the mechanic.

• A. on
• B. up
• C. of
• D. down

Answer 1

Answer: (D)

down

The given sentence mentions the action which will be taken if the car stops working. The option to be selected should convey the condition where the car has stopped working.

'breaks down' means to 'stop working', therefore the appropriate option to complete the given sentence is : Option D - down.

On the other hand, if breaks is combined with other options, ie. 'breaks on' means 'to get divided', 'breaks up' means 'split up, 'breaks of' means 'to split from something', it does not convey suitable meaning.

Therefore, the correct option is: Option A - down.

The completed sentence, thus, becomes : If my car breaks down, I'll call the mechanic.
