Which answer is correctly punctuated?

mexican food, in my opinion, is the most flavorful.
mexican food, in my opinion is the most flavorful.
mexican food in my opinion, is the most flavorful.
mexican food in my opinion is the most flavorful.

Mexican food, in my opinion, is the most flavorful.

Explanation:

The first sentence Mexican food, in my opinion, is the most flavorful is correct in it's use of the commas. The sentence can well stay independent even without the clause (in my opinion). But, with the addition of this phrase, it gives further description and meaning to the subject that is being talked about. This use of the dependent clause to further explain the sentence, also providing personal opinion,makes the sentence much clearer. Also, the use of the commas before and after the dependent clause, gives the correct form of the sentence. Thus, the subject is (Mexican food), clause (in my opinion) and the predicate being (is the most flavorful).

? ? what can you explain this to me i am so confused

explanation:

the intellectual community is a place like a university where people with high marks, or original thought or an outstanding interest in something gather. they take classes together. they discuss things. they argue sometimes, and not always in a friendly way. but if they argue, it is because they are passionate about something, and there is nothing the matter with that.

lately i've been hearing rumors that it is not the way it was when i went to school. the one thing all schools used to have was free speech. the 1st amendment rights were sacred. now i'm hearing they are not. students can be reported and disciplined for giving an off the wall opinion.

that is shameful.

intellectual ideas are meant to be discussed. they are meant to be chewed up and worked on. that is the primary responsibility of every intellectual community. if that is not the way it is, then that is not a school to go to.

social media, in my opinion, and this is just an opinion. i wouldn't take it too seriously, complicates everything to do with human communication. you can want to share things and others feel they have the right to be very critical or sarcastic or mean about what you share. lack of respect is an immeasurable intolerable condition and social media abounds with that sort of thing.

one of the things i really like about is how careful people are because they must have some idea that the mods are exactly what the word says they are. they police this board very well, and what is so remarkable about them is that they are no older than the average grade 12 student.

my hat goes off to them (which means i respect them quite a bit).
