Does the text contain a vague pronoun reference? At the conference, the authors met with some publishers to discuss their new books.

Yes.

Explanation: The text, "At the conference, the authors met with some publishers to discuss their new books", contains a vague pronoun reference because the pronoun "their" is a plural pronoun and the way the text is written, the pronoun "their" could refer to both nouns "authors" and "publishers". Since the pronoun "their" could refer to both "authors" and "publishers", then the text contains a vague pronoun reference as it is not clear whether the pronoun refers to "authors" or "publishers".

the proctors have three strikes against them in reverend hale's eyes. he is suspicious of them because they do not regularly attend church in the village, they have not baptized their youngest son yet, and john proctor cannot recite all of the ten commandments. i hope this < 3

its hard for me to see which word is supposed to be in bold. if i knew then i would be able to better.
