Test 48; Section 2; Question #13
« on: June 08, 2007, 06:17:53 PM »
How is the answer not D?  I count 4, through entailment, but the answer choice is 3?

Z has all three (because it has more than Y).
Y has only V and T (because it can't have equal or more than Z).

There's two.

X has R, but we don't know what else it might have.
W has either V or T or both.

Since S and Y do not have the same, it follows that S has R only.

There's three.

Now, what about U?  U has to have two.  But R can only go on three spots.  Since R is on S, X, and Z, it follows that U has to have T and V.

There's four.

The answer choice is 3.

Now, somehow I'm misreading what the answer choice is asking, I assume.  Can anyone help?

Nevermind.  I figured it out.  I misread the rule concerning three Rs.  It doesn't say there are only three.  It says there are three others, besides X, that have Rs.  Sorry to waste everyone's time.
