Answer

Brief Explanations:

Parallel structure requires items in a list to have consistent grammatical form. Option E mixes gerunds ("rowing, hiking, biking") with a clause ("you need to run more"), breaking consistency. Other options use uniform structures: A (gerunds), B (nouns), C (nouns), D (nouns).

Answer:

E. If you want to train well, you need to work on your rowing, hiking, biking, and or course you need to run more.
