Sat grammar

some paleontologists believe that mastodons died out because of human hunting, while others describe the animals’ extinction to climatic changes at the end of the ice age

the answer is “others describe” but why is it wrong?
can you guys help me?

“Describe to” isn’t right… You can describe something, but you can’t describe to it.

Ascribe, maybe?
Verb
attribute something to (a cause).
“he ascribed Jane’s short temper to her upset stomach”

Yep, “ascribe.”
