It wants "I am not able to" because poder means to be able to but when interpreting somebody, that should be fine. Remember, this is still a newish program and there will be some problems.
how is "no puedo" different than "yo no puedo"? It said I was wrong for writing just "no puedo"
Yes, it does, but in this sentence, the ideia is that it's allowed to do something, so you should use "can" instead using "may"
Technically the audio didn't function correctly i say something and it doesn't let me finish yet it says its correct
When I was in Mexico, I almost never heard anyone pronounce "Yo" as \joe. Why is her voice the one picked as the example?
I feel like "I can't do it" should be an accepted answer because doesn't "poder" mean "to do"?
"Poder" means "to be able to".
I can't do it = No lo puedo.
Needs the object pronoun.
You're adding in an extra negative.
Puedo = I can.
No puedo = I can not/I can't.
No, no puedo = No, I can not/No, I can't.
Because the correct answer is "I can not". Not "I do not." They do not mean the same thing.
I can swim. I have the ability to swim. I know how to swim.
I do not swim. It is too cold to swim and I do not have a suit.
