Please fix the official answers "My favorite animal are birds." and "She uses left hand to write."
The exercise at https://forum.duolingo.com/comment/27004992 has the official answer "My favorite animal are birds."
The exercise at https://forum.duolingo.com/comment/26913430 has the official answer "She uses left hand to write."
Both of these official answers use invalid English grammar. Their discussion pages indicate that both exercises are eight months old, so the error reporting feature doesn't seem like it's going to get them fixed.
I think more likely there are MANY things reported to them so they can’t get to everything immediately.
I have reported things and it was months later I got an email saying my answer was added as a correct response, so stuff is happening, it just takes time.
My favourite animals are birds seems like a very minor error. Missing an s.
The other one slightly less minor missing “her” from the middle of the sentence.
Even though there are still active contributors of the course (as shown in the incubator ), it appears they still haven't responded to reports. The ongoing concern throughout all trees (not only Chinese-for-English tree) is that
Contributors didn't spend more time, inputting all possible correct answers for each translation problem, since this will be very time-consuming for them to do that.
The only way to improve this is to have Duolingo hire more active learners not only being fluent in both languages, but also with some or very deep experience in technology. The reason why I said this is that not all answers are filtered intelligently to "match" the typed/inputted translations. Since the system does best in filtering translations with Roman characters, more English translations should be added to avoid some complicated issues.
The problem of this possible solution is that the chance of becoming a contributor will depend on the hiring competition for certain languages. As one of the "Incubator" forum threads suggested, if you do not hear any response about the application within one or more months, then try again!
Yes both these answers are
wong wrong! In my experience it can take them some time to correct the answers in the database.
With regards to the first one all the following are acceptable:
My favourite animals are birds...
My favourite animal are the birds...
My favourite animal is the bird...
And the second:
She uses her left hand to write...
She uses the left hand to write...
