Question

in snappy, modern slang.

1. i agree with some of the speakers ideas, but i find his enthusiasm for crackpot causes hard to take.

(select a word)
rabid
sparse

Explanation:

We need to choose a word that describes "enthusiasm for crackpot causes" as hard to take. "Rabid" means having extreme or fanatical enthusiasm, which fits the context of extreme enthusiasm for crackpot (unreasonable) causes. "Sparse" means thinly dispersed, which doesn't fit. So "rabid" is the correct choice.

Answer:

rabid
