My "I want to take this" wasn't accepted and the suggestion "I wanna to take this!" is wrong
Why would you say "wanna to". "Wanna" is a contraction of "want to". The correct answer is wrong and should be "I want to take this"
As people have already pointed out, the "correct" answer here is not correct. One doesn't say "wanna to".
Ooops! Yeah, a moment ago it accepted "I want to to take this" or "I wanna to take this"... fixed now. Thanks!
