Answer 2

Answer:

The mssing punctuation of the text is the following:

There was no drop in the author´s confidence when the film of his novel, which involved two years writing, was badly received by cinema audiences. The spokesperson for the studio defended the film´s release. It was an ambitious project. We’re very proud of it.

Explanation:

In the fist sentence, there is a possesive apostrophe missing (author´s confidence).

In the first sentence, commas should be place to separate the non restrictive subordinating clause from the rest of the sentence. Non restrictive clauses  are not esssential to the meaning of the sentence.

The second sentence starts with subject "The spokesperson" so a period should be placed before the subject. In this sentence we also should add a possesive apostrophe: film´s release.

The third sentence starts with the personal pronoun "it" acting as a subject so a period should be placed before the subject.

The last sentence is correctly punctuated.
