Practise do and does as simple present forms of the main verb do. Note: Because apostrophes can sometimes cause technical matching errors, it is better to use the full form when completing the gaps. If you use a shortened form, both the straight apostrophe (') and the curly apostrophe (’) are accepted.
Use do as the main verb in the simple present. Complete the sentence with do or does. For negative answers, the full form and both straight- and curly-apostrophe short forms are accepted.
