It is a simple sentence
A comma is not required there, but it would make the sentence read better.
Wasn't is singular, weren't is plural. If the subject of the sentence is just one person or object, then use wasn't. If the subject of the sentence is plural, use weren't."Sarah wasn't going to the store.""He wasn't going to the store.""John and Wanda weren't going to the store.""They weren't going to the store."
That does not agree it should be...."Vitamins that are sold in a health food store are not regulated by the food and drug administration."
The pronoun in the sentence is she, a word that takes the place of a singular noun for a female.
The pronoun "them" is an object pronoun. Subject pronouns are able to serve as the subject of a sentence, which in this case would be "they" not them. Example : "They went to the store." (subject pronoun) Example : "I saw them at the store." (object pronoun) The exception to the object rule is when the verb "to be" is used, creating an identity (although this can sound fairly odd if there is no modifying phrase). Example : "It is they who must be accountable." (i.e. They must be accountable.)
during black friday, the lines to get into the store squelched me.
The subject is the one doing the action or what the sentence is about. Examples: She is going to the store. (She is the subject). I am hungry. (I would be the subject). The action that takes place in a sentence is the verb.
Store
Jewish people close the store early on Friday to go to synagogue
Yes, pronouns (in this case, "she") can be used as a subject in a sentence. e.g. She went to the store. "She" is the subject.
John and Mary went to the the store.
No, "The bicycle in front of the store" is a phrase, not a complete sentence because it lacks a subject and a verb to form a complete thought.
The subject of a sentence is WHO or WHAT the sentence is about.Examples:The man went to the store. The subject is man.My mother is at work. The subject is mother.John hit his head. The subject is John.That store is my favorite. The subject is store.My daughter's friend is home from college. The subject is friend.You are smart. The subject is you.He is my friend. The subject is he.Kevin's car crashed into a tree. The subject is car.This computer is awesome. The subject is computer.That cute, little baby smiled at me. The subject is baby.For each sentence, just ask WHO or WHAT is the sentence about. That is the subject. The subject is always a noun or a pronoun.
"Mrs. Smith went to the store." Or: "She went to the store." Never "Mrs. Smith she went to the store." The subject of the sentence is "Mrs. Smith" - if you also have "she" then you have the subject in there twice (if this will help you to remember that you only need one of these).
