Question

add or remove punctuation, if necessary, from the sentence below.
peter parker covered the lumpy mashed potatoes,
that he was having for breakfast, in butter and
gravy.

Explanation:

The clause "that he was having for breakfast" is a restrictive relative clause—it provides essential information about which mashed potatoes are being referred to. Restrictive clauses do not require commas around them, so the commas before "that" and after "breakfast" should be removed.

Answer:

Peter Parker covered the lumpy mashed potatoes that he was having for breakfast in butter and gravy.
