Question

Fill in the blank choosing suitable modal from bracket:
(may, should, will, can)
________ you please help me by giving me change?

Answer 1

In this sentence 'can' or 'will' can be used in the blank as both the modal verbs are used to make requests or to express the possibility of something happening.

The main use of 'should' is to tell somebody what they ought to do, to give advice, or to add emphasis to something and 'may' is mainly used to give permissions. Neither of these usages would fit in the sentence and hence both are incorrect answers.
