Question

fix any punctuation or capitalization errors below. click \submit answer\ if there are none.
there was only one thing to do; smile and applaud as ferb fletcher accepted the award.

Explanation:

The semicolon is incorrectly used here to introduce a phrase that is not an independent clause. A colon is the appropriate punctuation to introduce the specific action that follows the statement of "one thing to do." Additionally, "Smile" should not be capitalized after the colon since it is continuing the same sentence, not starting a new independent clause.

Answer:

There was only one thing to do: smile and applaud as Ferb Fletcher accepted the award.
