Question

correct the text by inserting three commas. (note: in this skill, serial commas are not optional.)
mr. rudd planted geraniums lilies tulips and lilac shrubs around his patio.

Explanation:

To correct the text, we need to insert commas to separate the items in the list of plants. The items are geraniums, lilies, tulips, and lilac shrubs. We insert commas after "geraniums", "lilies", and "tulips" to properly separate the list items (since serial commas are required here).

Answer:

Mr. Rudd planted geraniums, lilies, tulips, and lilac shrubs around his patio.
