Answer 1

Answer:

option C: didn't communicate

Answer 2

Their marriage wouldn't be so good if they didn't communicate so well with each other.

Explanation:

• The given sentence emphasizes the need for communication between people during a marriage.
• Grammatically, the sentence involves a  third-person plural subject with the verb in the past tense. In such a  case,  the auxiliary verb 'didn't' is used, instead of don't. The auxiliary don't is used in the case of the present tense.
• The word didn't is a short form of did not.
• In addition, the given sentence is a conditional and negative statement with modal wouldn't; hence, didn't is the axillary verb that should be used.
