1. A

   Out of Scope: around the block3% picked this

   Test-drives of Zenith cars are, according to Zenith sales personnel, generally more extensive than a drive around the block

   This answer is dwelling on the extraneous salesman language of "if you so much as drive this around the block ...". We're not being asked about the advertisers conclusion. We're being asked about whether we could infer that the Zenith has unusually impressive quality. If over 80% of people are taking Zenith's on a lengthy test drive in varied driving conditions, then they are getting more chances to be impressed with Zenith's quality, and so if anything this might strengthen the Implication.

   Usually dealers have enough Zenith models in stock that prospective purchasers are able to test-drive the exact model that

   Those who take test-drives in cars are, in overwhelming proportions, people who have already decided to buy the model driven unless

   Why this is right

   This sounds like our prediction -- an alternate explanation of the over 80% stat is that the test driver had already decided on this car, and the test drive was a formality to make sure the car ran okay. It's a spin on a classic form of Alternate Explanation - Reverse Causality It's not that the test drive caused them to want to buy the car, wanting to buy the car is what caused them to test drive it.

   Out of Scope: same/different day7% picked this

   Almost 90 percent of the people who purchase a car do not do so on the day they take a first test-drive

   Nothing in the paragraph describes or cares about when the test driver buys the car. We just know that over 80% of those who test drive end up buying one (could be same day, could be weeks later).

   Too Weak8% picked this

   In some Zenith cars, a minor part has broken within the first year, and Zenith dealers have issued notices to owners that the dealers

   This answer would potentially hurt the plausibility of the claim that Zenith's are unusually high quality, but it's too weak. In "some" (at least one) Zeniths, a minor part breaks and the dealers replace it with an improved part at no cost. No one expects cars to be perfect, so the fact that some cars had a minor glitch that was fixed for free does not seem like an indictment of the quality of the car.
