Anonymous  +  410094 Mon, 27 Aug 07 06:04 PM Hi, How should one use which with is and are, as in... Is there a hard and fast rule? Which of these ARE/IS correct ? Of these theories, which ARE/IS correct? Thanks Anonymous

	Grammar Geek  +  410108 Mon, 27 Aug 07 06:14 PM Yes, there's a very simple rule. Is one correct? Then "Which (of these) is correct?" Is more than one correct? Then "Which (of these) are correct?" The same with the theories. If there is only one that is correct, use the singular "is." If the possibility existst that two or more or corect, then use the plural "are."
