I think chilli is a better translation, like greg said pepper causes confusion.
Why have a capital letter on the correct option? That's not learning, it's guessing
Yea, capitals giving off proper answers are dumb. Try solving the question without looking at the possible answers. This is what I do.
This should accept all these:
- chili pepper
- chilli pepper
- hot chili
- hot chilli
The current default is a fine choice since it's not ambiguous.
Not only are there many kinds of peppers, there are many kinds of chili peppers. I'm pretty sure what Koreans call 고추 is 'cayenne pepper'.
