Question

Fill in the blank with the most appropriate word.
Susan will probably work _____ six.

• A. for
• B. under
• C. until
• D. by

Answer 1

Answer: (C)

until

The correct answer is option 'C' 'until'

The given sentence indicates that Susan will be working up to six o'clock. Thus, the preposition of time used must indicate that.

Option A is incorrect. Using 'for' will mean that Susan will be working for a time period of 'six'. Since the unit of the time is not mentioned, the use of for will make no sense. Thus, it is incorrect.

Option B is incorrect. Using 'under' will mean that Susan's work will be done before a time period of 'six' is over. This will not make any sense and is incorrect.

Option C is incorrect. 'until' means 'up to'. Thus, it means that Susan will be working till 6 o'clock. Thus, it is the correct answer.

Option D is incorrect. 'by' means 'no later'. Since we have to indicate the time Susan will be working up till and not the point of time she will be done by, 'by' is the incorrect answer.
