Is this sentence actually correct or just “sounds” correct to me?
i keep getting stuck on a small grammar doubt and wanted a second opinion
when people say something like:
“the system improves performance by analyzing large datasets and identifying patterns”
it feels correct, but when i try to rewrite it, i end up with things like:
“the system increases efficiency by examining big sets of data and finding patterns”
my question is — is there a real grammatical difference between these two, or is it just vocabulary choice?
both seem structurally similar to me, and that’s where i get confused
also at what point does a paraphrase become “too close” in structure vs just being normal rewording?
i’m not trying to change meaning, just understand what actually makes a sentence distinct in English writing rules
