Because if you had 5 C's then you'd have to have at least 3 paired with the same colour - which is a violation of the question stem; and you can't have more than 4 C's, so the remainder have to be W's. And it's not B because two C's could be paired with B/G and only one 1 white shade - the remaining W's could be all green.

It's asking you what must be true. So lets make a hypothetical where (B) doesn't occur to prove B wrong.

I hope this formats correctly.


Ceramic or Wooden:::: C C C C W W W
Brown, White, or Grey: B G G W G G G

Here we have 4 ceramic lamps and 3 wooden lamps.

We have one brown lamp, one white lamp, and five grey lamps.

Let's see if this hypo works:

At least four of the lamps are ceramic (Yep).

If White shade, the lamp is ceramic (Yep.)

No wooden lamp has a brown shade (Yep).

(B) tells us that two of the lamps have white shades. But in my hypo, only 1 does. And I'm not violating any rule.

I'm not the OP, but it's not. One of the random test prep company free sample problems.

Correct. With thousands of LSAT problems in existence there's no reason to.
