Question

Fill in the blank with the most appropriate option:
What ______________ on Sundays?

• A. all usually do
• B. do all usually do
• C. do all usually
• D. usually does all do

Answer 1

Answer: (B)

do all usually do

When we form a question with 'what', we usually invert the word order of a positive sentence, where the form is 'what + auxiliary verb + subject + main verb'

Option B: 'Do all usually do' follows the form given above: do (auxiliary verb) + all (subject) (+ usually is an adverb) + do (main verb).

Hence option B is correct.

Option A: 'All usually do' is missing the auxiliary verb 'do'. Hence this phrase is incomplete and A is wrong.

Option C: Similarly, 'do all usually' is missing the main verb, hence C is incorrect.

Option D: In 'usually does all do', 'does' is a singular verb and does not agree with the subject 'all'. When the subject is plural, the verb must also be plural. Hence option D is incorrect.

('Do' can function as an auxiliary verb as well as a main verb.)
