Question

add or remove commas, if necessary, until the sentence has correct punctuation. after scoring the winning goal, okoye jumped up and down, ran around in circles, and did two backflips.

Explanation:

The original sentence has correct punctuation. The comma after "After scoring the winning goal" is used correctly to separate the introductory clause from the main clause. The commas between "jumped up and down", "ran around in circles", and "did two backflips" are used correctly to separate the items in a series.

Answer:

After scoring the winning goal, Okoye jumped up and down, ran around in circles, and did two backflips.
