It depends on whether it's singular or plural, Cheshire. Eg.:I saw 10 times more google hits of "than was possible" than those of "than were possible," which is also said for "than is possible" over "than are possible."
Is "than were/are possible" wrong?
Well, aren't you kind! With all due respect to Setwale Charm, it should be "were ever possible" because "shells" is plural. Eg:Dimcl, your my lovely mentor
I don't get why "than were possible" in the following thread is not right. Could you tell me why?
