A recent SAT "ID the error" question reads: Although it is *widely regarded* as a masterpiece now, *when* it was built A B the Eiffel Tower was compared to a "ridiculous smokestack" *by them* who did C not *approve of it*. *No error* D E C just sounds wrong. I would say "by those who did not approve of it." But isn't the "them/those" word the stand-alone O.P. of *by*, unaffected by the relative clause that follows? This does not seem to be dealing with the who/whom question; "who" is correctly the subject of "did not approve." So why is this an error?
