Peaceblinkfriend  +  529594 Thu, 19 Jun 08 02:31 PM I know this is probably a basic grammar question but why is it 'one of the thick tubes that carry blood from the heart to other parts of the body' and not 'one of the thick tubes that carries blood from the heart to other parts of the body'?   Thank you PBF Peaceblinkfriend Joined on Wed, May 9 2007 Senior Member 2,130 Success - it is not the position where you are standing, but which direction you are going.

	Mr Wordy  +  529605 Thu, 19 Jun 08 02:48 PM It's grouped as: One of [the thick tubes that carry blood from the heart to other parts of the body]. So "carry" agrees with "tubes". [One of the thick tubes] that carries blood from the heart to other parts of the body. is, I suppose, theoretically possible, and would mean there are many thick tubes having different purposes, and we're referring to one of those whose function happens to be as stated. If I meant this, though, I would rewrite it to avoid possibly ambiguity or misinterpretation. Mr Wordy Joined on Tue, May 27 2008 Senior Member 2,359 Native British English speaker
