Answer :
To write the given sentences in the negative form, we need to add the word "not" to each sentence. Here are the negative forms of the sentences provided:
a. They do not pay the bills in time.
b. She does not like to read science fiction.
c. Pine trees do not grow in this forest.
d. It does not help to be tactful.
e. They do not waste money on marriages.
By adding "not" to these sentences, we change them to negative statements, indicating the absence or denial of the actions described in the original sentences. This transformation helps convey the opposite meaning of the initial statements.
