Why is (D) correct? I thought "made with screens" was referring to the tiles, but the stimulus says that the tiles are small. How are we supposed to infer that the tiles/screens themselves are large?

I'm also confused as to why that is the answer because the stimulus said "small enough to be quite bright". I feel like it's a stretch to say that the tiles are very large.

Or is the answer choice talking about the compound televisions in general, not the tiles?

[Dana D]

The stimulus presents us with several facts regarding new television screens. If we add together all the information presented in the stimulus, we learn the following information about the new TV sets (understood to be the entire television):

- These TVs are only a few inches thick (we get this from the sentence that says "Television sets with these compound screens are just a few inches thick.")

- The screen of the TV is actually a compound screen made up of many smaller screens.

- Each of these small screens can be bright (according to the sentence that says "However, each tile in a compound screen is small enough to be quite bright. ")

- Compound TV screens can be made to be very large without sacrificing brightness or adding thickness to the overall TV set (from the sentence " Moreover, an unlimited number of the tiles can be joined together, without making the resulting screen any less bright or the set any thicker")

Answer choice (D) reiterates this last bullet, saying "Television sets that are just a few inches thick can now be made with screens that are both bright and very large." We know this must be true, because TV sets with compound screens can be only a few inches thick, but with a very large screen that is also bright.

Be sure to pay attention to the way the stimulus is referencing different ideas here - 'tiles' are in themselves little screens, which can be assembled next to each other to create one much larger screen. Think of the side of a brick building - each brick is a 'tile' or a small TV screen, and assembled together they can make one much larger wall, which would be the entire compound TV 'screen'.

Hope that helped!

I didn't pick D because it mentioned "large screens" and as I understood Compound TVs are made of Smaller tiles/small screens. I went with E instead. Could you please clarify D further with this in mind and why E is wrong?

LawSchoolDream,

"Tile" and "screen" are not interchangeable. The stimulus tells us that the screens are compound and made of multiple tiles. That was your issue, then - you conflate them. The small tiles are not screens at all. The screen is the compound.

Answer choice (E) is wildly out of scope. The compound screens can be big and still bright. We know just about nothing else about them, so knowing they have no disadvantages is simply new information.
