Answer :
Final answer:
Option B, with a colon, is the correct way to fill in the blank for the provided sentence, as it properly introduces the list of skills learned by the age of ten.
Explanation:
The correct way to fill in the blank in the sentence "There are three skills that I learned by the time I was ten years old _____________________________" is with option B, which uses a colon. A colon is used to introduce a list or an explanation that is directly related to the clause before the colon. Therefore, the complete sentence should read "There are three skills that I learned by the time I was ten years old: how to fly-fish, how to hunt deer, and how to tie my shoes."
