Hi there,Let me walk you through this step by step.
First, let's identify the argument's structure:
-
Conclusion: Richard is a terrible driver.
-
Evidence: He has had at least
five traffic violations in the past year.
Now ask yourself: does the evidence AUTOMATICALLY prove the conclusion? Not quite. The argument jumps from 'traffic violations' to 'terrible driver' without ever explaining WHY one leads to the other. The author is ASSUMING that having
five or more traffic violations makes someone a terrible driver. But that assumption is never stated — it's hidden beneath the surface.
Maybe those violations were all parking tickets. Maybe they were technicalities. The argument works ONLY if you accept the
unstated bridge: traffic violations = terrible driving. That's a
concealed assumption.
Now let's eliminate the other choices:
A) Ad hominem means attacking the person making a claim instead of the claim itself. But here, nobody is making a claim that's being attacked — the argument is simply drawing a conclusion about Richard. Not a match.
B) Appeal to authority means citing an expert or authority figure to support a claim. No authority is mentioned anywhere. Not a match.
C) Argument by analogy means comparing two similar situations. There's no comparison happening here. Not a match.
E) Ambiguity/equivocation means a word shifts meaning mid-argument. No term changes meaning here. Not a match.
That leaves
D — the argument relies on a hidden, unstated assumption connecting traffic violations to being a terrible driver.
Key Takeaway: Whenever a conclusion seems to 'leap' beyond what the evidence directly states, look for the unstated assumption that bridges the gap. That hidden link is often the key to understanding an argument's structure.Answer: D
