Sentence Correction

Hello.

In question 82 of verbal review 2, OG explanation says that "the areas described would suffer from both little water and few services at the same time, so the correct conjunction is and, not or".

The below is modified version of the sentence:

"the new law permits fewer people to live in areas where there are little water or few services.

I know that "and" and "or" convey different meanings, but I do not see any illogical meaning if we use "or" instead of "and".

Please explain what the illogical meaning is if we use "or".
---------

is the below sentence redundant? I think "there are" and "available" convey the same meaning.

"there are little water and few services available"

Thank you.

Because "and" and "or" convey different meanings, you need to take a pause and think about what the author of the sentence is trying to say, then pick the choice that better reflects his intent. You're right in suggesting that there is nothing illogical about "or" in "areas where little water or few services exist". "and" is better because it reflects what the author is trying to say, when you consider the meaning of the sentence as a whole.

"there are" and "available" do not necessarily cause a redundancy. I can imagine a situation in which there are 10 city services, but only 3 of them are available in the zones the sentence discusses.

If you have trouble making sense of the OG explanations, consider a source that has more in-depth explanations to OG questions. The solution below is taken from the GMATFix App.
