Q. Find the plural or possessive error. Select it and type it correctly.

William Wordsworth departed from the convention's of eighteenth century  poetry, which valued aristocratic, heroic language. Wordsworths' Romantic  style of poetry used more natural, everyday language.

Convention's - Conventions

Explanation:

The plural nouns that end with the letter '-s' employs an apostrophe(') followed by the word to display ownership or possession while in the singular case, the words must employ the letter 's' followed by the apostrophe(') to display possession even if it ends with the letter 's' or not.

As per the context of the given passage, the word 'convention's' in the first sentence is grammatically incorrect as the author aims to display the plural form of convention i.e. 'conventions'(or traditions) instead of showing possession. Thus, the correct form would be 'conventions' to convey the appropriate meaning to the sentence as Wordsworth broke away from the neo-classical traditions and gave significance to emotion, freedom, and individual imagination.

the correct answer is "dissent"

explanation:

because dissent is when one or more judges express disagreement with the majority in court, in specific legal systems.   an   argument in opposition is presented to the court, with a different interpretation, or application.

impartial means: treating all rivals or disputants equally; fair and just.

i would say that impartial is agreeing with something, because impartial means to treat your rivals, arguments, and reasoning equally and fair. so if you rival says something, agreeing on it means you did the impartial.
