Answer 2

Answer :

This question is based on modal verbs.

Cambridge English Dictionary defines 'modals' as 'a verb, such as "can", "might", and "must", that is used with another verb to express an idea such as possibility that is not expressed by the main verb of a sentence.'

So, the complete sentences formed using modal auxiliaries are as follows :

(i) You should keep your surroundings clean.

(ii) All of us must avoid unhygienic food.

The underlined words 'should' and 'must' are modal verbs or modal auxiliaries.
