Step-by-step explanation:
I have been to complete the sentences.
We see the use of the words in bracket. The use of "will" and shall" are used here. "Will" is used in affirmative sentences and also in negative sentences. It is also used when making requests. "Shall" is used is used when describing obligations.
We see the use of the conditional word "if" used in each sentence. It means that if this happens, that will take place/happen.
