"Does there exist" is perfectly logical.
I thought so too, but it's not accepted. For given answer including "Is there..." I would expect to see the verb "haver" or "ser."
I agree,but they say it is wrong
Didn't like '...way of avoiding...' Reported, harumph!
I agree! Many times I have translated word for word only to have DUO tell me that the correct answer uses the gerund in the English translation of the Portuguese infinitive. Also, 'de' normally means 'of' rather than 'to'.
using the gerund is correct, not wrong
"Is there a way to avoid this?" was accepted.
what is wrong with "is there a way of avoiding that?"
