Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
The main idea of a text is the main subject that the text addresses, the subject on which all the arguments presented are based. You will be able to understand this idea by reading the full text and identifying what the text is about. In this case, the key sentence of the text is the sentence that presents this subject in the most direct way possible. Generally, the main idea and the key sentence of the text are presented in the first paragraphs.
To develop the main idea, the text presents details, which are sentences that support this idea, showing how it is relevant and why it is true. These details are present throughout the text.

I've always been taught that revising involves checking for spelling, punctuation, and grammar. Basically any kind of improvements. Is this one of those questions where you check all that apply? Revising also includes making sure you have stayed on topic and gives you the chance to remove things that may not really apply or add other things that may have been left out. It's where the writer truly polishes everything up.
I hope this helps.
Answer:
It's subjective. Both sincere and insincere can be argued.
Your question is incomplete because you have not provided the underlined pronoun. Thus, the complete sentence is the following:
Nathan told Nadir that <u>his</u> nerves would impact the horse's ability to carry them through the competition.
Answer:
Case: nominative
Reference: ambiguous
Sentence rewritten: After seeing that Nadir was nervous, Nathan told him that nerves would impact the horse's ability to carry them through the competition.
Explanation:
The possessive adjective his functions as nominative case because the noun phrase his nerves functions as the subject of a verb. Besides, it creates ambiguity because it is not clear whose nerves it refers to - Nathan or Nadir's. As a result, it is necessary to rewrite the sentence to clarify whose nerves affect the horse's performance.
