Passage Summary: An expert says most cars need regular transmission service or they will break. Wei says the expert is wrong because his own two cars have never been serviced and are doing just fine after a decade.

Conclusion: The expert's claim that most cars need transmission service every three years to avoid problems is incorrect.

Reasoning: The speaker has owned two cars for twelve years without ever servicing the transmissions, and neither car has had a problem.

Analysis: Wei is making a classic mistake by using a tiny, personal sample size to try and debunk a general statistical claim. The expert didn't say *every* car would fail, only that *most* would. Wei's two cars are what we call 'anecdotal evidence,' which isn't enough to disprove a trend involving the majority of vehicles. Look for an answer choice where someone uses a single personal exception to claim a general rule is totally false.
