"They will continue walking."
Translation:Ellos van a continuar caminando.
If you use caminar, I'm pretty sure it implies that you thought they might have become paraplegic (e.g. after a car accident) but, in fact, they will continue to walk. Linguists call that a "rescue reading"; when you find a far-fetched (often science fictional) interpretation for an otherwise-invalid sentence. I meet some native-speaker friends every Wednesday, so I'll ask for confirmation.
I'm not sure because I think that would mean "They are going to continue to walk"...having said that, Duo normally accepts "to walk" or "walking" as in this context they basically mean the same thing.
In summary, I don't think 'caminar' would be the best choice, but I think that it should be accepted. Hopefully someone else will be able to give a definitive answer.
The sentence in English is ambiguous, but only one of those meanings is used to translate, the other is marked as incorrect.
It could mean "they will continue walking, after this stop" or "they started out by car, and will continue walking"... Maybe a little more context would make this one easier!
If there was a point in which the person stopped moving, then caminar is right. If the person is simply going on them caminando is right. Duo only accepts caminando, but seeing as how a lot of people here just came from the medicine section it should also accept 'a caminar' since we were a little primed for this question. Definitely should accept both.
I'm also confused as to the difference between a)"Ellas van a continuar caminando" and b)"Ellas van a continuar caminar".
Is it that a) is used when we are talking about people who are walking right now, and b) is used when we are talking about the state of affairs/capabilities in general?
So maybe, a) would be used if I've just talked to a group on the phone who is on their way to meet us, but b) would be used if we're talking about a senior citizen group who have been offered, but turned down, the possibility of a communal bus to the supermarket once a week?
