This is a case of being precise/specific or not. If you ask someone to choose from a selection of chocolates, you can say simply: Which would you like? or if you want to more precise: Which one would you like?
In addition to what Alan wrote, here is my comment:
[color=blue]one => which one
[color=red]more than one => which ones
(You have enough money to buy an additional program for your new PC.)Which one do you want? (You have enough money to buy a few additional programs for your new PC.)Which ones do you want?
If you only say “which”, it will often be unclear whether you’re referring to just one or to more than one.
a.One or more of a number of people or things , especially when it does not matter which (one).
b.One or more of a number of people or things , especially when it does not matter which (ones).
Is “it” in this sentence impersonnel?
If yes, the real subject is which one(s) and:
Can I aloso say:
c.One or more of a number of people or things , especially when which (one) does not matter.
d.One or more of a number of people or things , especially when which (ones) do not matter.
a and c are the same meaning?
b and d are the same meaning?
It’s best to forget about using “one” or “ones” in your particular sentence. The word which (alone) works the best.
Your sentence starts off with “one or more”, so it is therefore better to use just “which” in the second half of the sentence because it’s unclear — “Which” can refer to “one” or “ones”.
In order to use one/ones and produce a completely logical sentence, you’d have to write something like this:
One or more of a number of people or things , especially when it does not matter which one or ones.
This is a good example of why using the word it is better. Then the verb agreement isn’t a problem.
Using the words one or ones in the sentence “One or more of a number of people or things , especially when it does not matter which one or ones.” is complete overkill. The words “one or ones” are completely unnecessary and redundant.
If, for whatever reason and despite my advice :roll:, you absolutely must say “when which one or ones does not matter”, then it is fine to use “does”.
1/ Please only tell me correct in grammar or not correct in grammar.If not correct, please tell me the reason and fix it:
a. One or more of a number of people or things , especially when which one or ones does not matter .
b. One or more of a number of people or things , especially when which does not matter .
2/ Can you tell me the rule for the accordance of the verb with: (In general).
S1 + or +S2 + V
For you, the is in accordance with S1 or with S2 or with both?
