Answer 2

Answer:

There is no water in the tank, is it ?

Explanation:

I have always used the phrase "some water" and "a little water" interchangeably. Recently I took an English quiz and the question was :

Please give me (a little / some) _____ water to drink.

I marked 'some' as the correct answer but found out that 'a little' was correct. Searching similar sentences on Google also confirms this. Is the use of 'some' here incorrect?

PS: I found many sentences where 'some' is used in this construction :

Please, may I have some water in a cup

Is there any reason for using the specific phrase in that context?
