D.

Answer 1

C.

"Known not only for his achievements... but also because he bravely lives..." is not parallel: "for" + noun phrase vs "because" + clause. Fixes:
- "Stephen Hawking is known not only for his achievements as a physicist but also for bravely living with ALS."
- or "Stephen Hawking is known not only for his achievements as a physicist but also for his bravery in living with ALS."
