Use a comma to separate three or more items in a series. Use a comma to set off a phrase or clause at the beginning of a sentence. Use a comma to separate coordinate adjectives. Use a comma to set off a parenthetical element in the sentence.

Answer 1

Use a comma to separate coordinate adjectives.

It is breaking this rule: "Use a comma to separate coordinate adjectives." There should be a comma between "new" and "very" because these are both adjectives.
