I have no idea why you are so concerned to replace the use of "which" as a relative pronoun by "that", but please don't keep doing it unless you can give a good reason. The editor who uses the pseudonym "JamesBWatson" (talk) 08:53, 18 April 2014 (UTC)
- Your edit summary for this edit is interesting. I read "The study of field extensions (and polynomials which give rise to them)" as meaning "the study of field extensions (and the study of those polynomials which give rise to them)", whereas you evidently read it a meaning something more like "the study of field extensions (and the study of polynomials: polynomials give rise to field extensions)". However, if the sentence is read in the latter way, it is wrong, because Galois theory is not the study of field extensions and of polynomials: it is the study of field extensions and of the particular polynomials which give rise field extensions. I also see no justification for the brackets, which seem to suggest that the polynomials are somehow incidental, whereas Galois theory, as I see it, is fundamentally about the relationship between the field extensions and the polynomials, both of which are essential partners, neither of them incidental or parenthetical. I would prefer something like "The study of field extensions and their relationship to the polynomials that give rise to them via Galois groups is called Galois theory" agreed. (Actually, I would even more prefer the same sentence with "which" in place of "that", but I am willing to compromise on that, knowing your opinion on the matter.) Any thoughts? By the way, I'm afraid my talk page is currently semi-protected to prevent disruptive edits by another editor, but I will try to remember to check here to see if you answer. You may like to create an account, which after a little while would prevent you from being affected by page semi-protection, together with various other benefits.
