The argument asserts that all residents in a city support a proposed bike lane, implying its success. Which flaw best characterizes this reasoning?

• A. Generalization from a diverse population.
• B. Overreliance on data.
• C. Not considering cost.
• D. Failing to mention environmental benefits.

Answer: (A)

The main idea here is that of making a sweeping generalization from a varied population. In a city, residents hold a wide range of views; concluding that all residents support the bike lane just because there is some support (or because the population is diverse) assumes universal agreement without evidence. This ignores dissenters, undecided voters, and the practical reality that broad consensus is rarely guaranteed. A sound argument would need representative data showing near-universal support or would need to show that broad approval translates into actual, sustained success.

The other options miss the key issue: focusing on data quantity or reliability (overreliance on data) isn’t the core flaw since the problem is assuming everyone supports the proposal, not how much data they've collected; ignoring costs or environmental benefits would add missing considerations but wouldn’t capture the logical leap from “some support” to “all support.”
