Question

correct the text by inserting two commas. (note: in this skill, serial commas are not optional.)
michael jackson was a singer a songwriter and an inventor. he held a patent for a special shoe that created the illusion of antigravity.

Explanation:

To correct the text, we need to use commas to separate the items in the series "a singer, a songwriter, and an inventor" (since serial commas are required here).

The sentence lists three roles of Michael Jackson: singer, songwriter, and inventor. In a series of three or more items, we use commas to separate each item, including before "and" (serial comma). So we insert commas after "singer" and after "songwriter".

Answer:

Michael Jackson was a singer, a songwriter, and an inventor. He held a patent for a special shoe that created the illusion of antigravity.
