Passage Summary: Sam argues that a car brand is high-quality because recent buyers are happy. Tiya counters by noting that some car problems don't show up until the car has been driven for a few years.

Conclusion: Starlight automobiles are largely free of manufacturing defects because recent buyers report high satisfaction.

Reasoning: Ninety-five percent of buyers from the previous year are satisfied, and people with defective cars are generally not satisfied.

Analysis: Tiya is pointing out a temporal flaw in Sam's evidence. Sam assumes that if a defect isn't making a customer unhappy right now, it doesn't exist at all. Tiya's role is to provide a reason why Sam's evidence—satisfaction within the first year—is insufficient to prove his conclusion about the total absence of defects. Look for an answer that describes Tiya's response as introducing a consideration that undermines the force of Sam's evidence.
