Question

Choose the word or phrase that best completes the sentence.

Jasmine is working as a dental assistant. What she does is ________ people's teeth.

• A. clean
• B. cleans
• C. cleaning
• D. to clean

Answer 1

The correct option is A clean

Option A is the correct answer because ‘ to clean’ means to clear a place from something, here teeth from dirt or germs, and it is correct because it is being preceded by ‘does’.

Option B is incorrect because ‘cleans’ doesn’t need to be preceded by a specification like ‘what she does is’, which is incorrect, it would be correct if the statement was’ she cleans people’s teeth’.

Option C is incorrect because ‘cleaning’ means it a process going on in the present, which is incorrect.

Option D is incorrect because ‘to clean’ would be used when the statement was, ‘her job as a dentist is to clean peoples teeth’, that is ‘to clean’ has to be preceded by “to”.
