Thank you so much Annabel! Your explanation made a lot of sense. I see how your sentence is much better than mine. Thank you!

A. Cog : wheel B. Pick: ice C. Bit: drill D. Pulley: rope E. Wood:screw I picked A, because my sentence was "a saw has many teeth", so "a wheel has many cogs" fit best. but the answer the book (Princeton Review, 2010) gave was C. their sample sentence was "teeth is the cutting part of the saw". I don't see how their sentence is better than mine. Any pointers? Thanks!!
