"There is 32 litres of water" (instead of "there are") sounds like an acceptable answer as well, no?
In some dialects, it is fine. It is considered grammatically incorrect though in terms of Standard English :) (I actually say this and my Turkish students would correct me, their American English teacher)
Yip, sounds totally natural to me (I am a native English speaker). I agree with Alex that it isn't standard. (It appears that they have taken the stance of being picky with English grammar in this course).
In this case 'is' sounds better as the body of water is one unit which happens to be 32L in volume.
In English most people wouldn't say there 'is' 33 liters of water. Liters is plural, so it should be 'are'. Using is here sounds slightly uneducated.
Merhaba! Does anybody know why the sentence "Kirk iki tane köpek var." Uses TANE for "there are" but it doesnt seem necessary here? T
Totally off topic, but I find it weird that the US has their own spelling of litre / liter and metre / meter considering they don't even use the metric system (except in technical fields).
Liter in my device has got two "t" and Duo keeps correcting me but i can not do any thing .please leave it .
