I opt for 'no comma'.
Yes, a comma should be placed before "i.e." to separate it from the rest of the sentence.
No.
No, a comma is not needed before and after the word "again" if it is in the middle of a sentence.
A period should come before the footnote at the end of a sentence, while a comma should not.
Yes, you should put a comma before "as" when it is used as a conjunction in a sentence.
no. if but before is a sentence on its on and after but is a sentence on its own then put a comma before but.
The "comma"is before the word"but"because if you had a sentence that your teacher wants you to write,that sentence would be called a"compound sentence".A compound sentence is a sentence that have the words"but"and"and".(example.I want that dog ,but I changed my mind.)
In general, when "but" is used as a conjunction, a comma is not needed before it. However, if the phrase following "but" is an independent clause, then a comma is typically placed before "but."
no!!
Yes, in most cases, a comma should be placed before "of whom" in a sentence. This comma is used to set off a dependent clause or phrase that is providing additional information about the subject.
A comma should generally be placed before brackets if it is part of the main sentence structure. If the brackets are used for additional information within a sentence, then the comma should go before the opening bracket.
A comma before "which" depends on whether it introduces a nonessential clause. If the information following "which" is necessary for the sentence's meaning, no comma is needed. However, if the clause is nonessential, a comma before "which" is appropriate.
