"This dress needs to be hand washed."
”这条裙子要用手洗“ Still not accepted as of 2019-03-24. Reported.
Interestingly, the audio lesson does not use 件. It uses 条.
Also suggested "这条裙子一定手洗" as an alternative answer. We were never taught 要用, but we have seen 一定.
"这条裙子一定手洗" seems to be missing a modal verb. I'd want to put "要" or "要用" after "一定".
Isn't "条" MORE correct than “件" in this instance?? And how the hell does duolingo not accept 条 when it LITERALLY GIVES THAT IN THE CHINESE→ENGLISH VERSION OF THIS EXERCISE?
