Actually, yes, this is true. Let's look at some examples with the word "all" to see if it agrees with verbs in singular or in plural:
All is lost
All is well
All is arranged already.
All of it is nice
This shows us that "all" agrees with verbs in singular form: the correct answer is a) True.
I believe the answer is 3rd person
I think it is B because A is an opinion, C is not directly addressing the subject and D doesn’t have anything to do with the subject. Hope this helps
(If I’m wrong plz tell me why)
Explanation: A writer should always include a works cited page because you don’t want to be called out on plagiarizing. If you have quotes or information from a website, book, article, or any source you used then you need to give credit to that person/people because you didn’t come up with the information yourself.
