Answer:
Though Darren was not very athletic, Darren taught Micah to play football
Step-by-step explanation:
Though he was not very athletic, Darren taught Micah to play football.
In this sentence, the modifier “Though he was not very athletic” has the pronoun “he".
However, we don’t know who “he” is substituting for so we need to change the “he” into Darren.
