Answer:
He will have been writing a new novel by year end.
Explanation:
The future perfect continuous tense (also referred to as the future perfect progressive tense) is the tense we use to describe actions that will continue up until a point in the future. The formula is the following:
- Will + have + been + present participle (verb root + -ing)
The present participle of the verb to write is writing. This means that the future perfect continuous tense of to write is will have been writing.
