a choice between one of two options
I would like to know if this is correct grammatically. I came across it in a scientific paper. I think the “one of ” part should be removed. Am I correct?
The original statement is redundant and semantically awkward. Technically it's grammatical, I suppose: it is well-formed, but the meaning is wonky. It's not right to say you have a "choice between one", but that's not a question of grammar but of meaning.
is better than
but not because of the grammar.
Is it grammatically correct? Sure.
Can you remove “one of ” and have it still mean the same thing? Sure.
Should you do so? I can’t answer that. As written, it does seem longer than it needs to be, but scientific papers with word-count requirements are often that way. Nobody ever pays a scientist to publish good English, only to publish, period.
You could alternately remove “between one”. That leaves us with these possibilities:
Depending on whether you have two or more than two, you could also use:
None of these is a matter of grammar, merely of style.
It might be a bit awkward, and wordier than necessary; however, it's worth pointing out that you've given us the sentences in isolation, out of context.
Conceivably, there are times I might vote to leave that construct as it is, depending on the surrounding content. For example, if I was writing documentation for a software system, I might be talking about three input screens. In that context, I might say:
In that case, the language of the third statement parallels the other two, so I find less fault in it.
So, to answer your question (which was, “am I correct?”), I would agree that you may be onto something, but I wouldn't go so far as to say that the original wording is always inferior in all contexts.
The prepositional phrase "between one of two options" is grammatically correct because the noun phrase is "one of two options" and not "one". "Between one of two options" means "between one option and a second option", which would not appear grammatically incorrect to you, I assume.
Otherwise, I agree that this is redundant. It is also likely, poor style unless other context makes this structure flow better, as pointed out by JR. However, if I was reading a research article on a topic of interest to me, I doubt I would notice this. I suspect the co-authors, reviewers and editors spent more effort on the difficult concepts in the article.
I reviewed prepositional phrases and noun phrases for this, but do not know how to include a link on my device. Apologies for that.
