Reading the argument
Demand matters. Trying to sell LSAT lessons to someone shopping for jewelry could be difficult because that person wants something else. And the junkyards' interest in newer cars makes sense: they can sell the parts.
But junkyards aren't the only possible buyers. What about a parent buying an inexpensive old car for a teenager to drive? That buyer wants a working car, not an inventory of parts to resell. A car could be unattractive to a junkyard and still attractive to that parent.
What we’re looking for
The evidence is about selling to junkyards, while the conclusion is about how easy cars are to sell overall. For the required assumption, I'd look for a reason the difficulty with junkyards carries over to the broader market.
Working the answers
- A
Demand doesn't have to be the only influence on how easy something is to sell. The argument gives it a role, but price, condition, or other factors could matter too. Saying that higher demand makes selling easier doesn't exclude every other influence.
- B
All is too much. The argument could allow some older cars to be sold to people who intend to drive them. It needs the parts-demand problem to matter to overall salability, not every single sale to go through a junkyard. The parent buying a teenager's car needn't be impossible.
- C
We don't need a general rule about every kind of older item. Perhaps some other product becomes easier to sell as it ages. That would not settle whether older cars are harder to sell because of the demand for their parts. This choice is much broader than the argument's subject.
- D
This discusses how supply and demand affect the selling price of cars less than ten years old. Our gap concerns what makes older cars easy or difficult to sell overall. D doesn't connect the junkyards' lack of interest in old parts to the broader market for those cars.
- ECorrect
This makes the demand for older parts central to how easy older cars are to sell. If older-car sales depend largely on that demand, then the lack of demand described in the evidence has consequences beyond the junkyard example. Without that connection, buyers wanting complete cars could make old cars easy to sell even though junkyards avoid them.
'Largely' matters: E doesn't say every buyer wants only parts or that parts demand is the sole influence. It also doesn't say the parts are broken or poor quality. The issue is demand for them, which is what the premises actually discuss.
