Answer:
Explanation:
Commas are punctuation marks that separate and help organize words, clauses, and concepts in a sentence. They usually follow participial phrases that introduce a sentence.
An adverbial phrase such as "After eating lunch at the cafeteria" at the beginning of a sentence, should be followed by a comma. Nonrestrictive clauses such as "which was due to take place on Tuesday" are should be set off by commas. If a dependent clause is used to introduce a sentence, it should be followed by a comma.
