Which sentence does not contain any errors in comma usage? A. His new shoes look like big, brown torpedoes. B. This is the best,
and most interesting trip I've ever taken. C. The darker, thicker material will be better for the cushions. D. This long tiring and sweaty hike is no fun any more.
Ok, it can't be C because you never place a comma in front of the adjective which is describing the noun, unless their is 3+ descriptive words.
Commas never are used when there is an <u><em>'and' </em></u>set in front of it. Commas generally mean <u><em>'and'</em></u><em /><em />. So therefore don't need to be used again, so we can eliminate B.
