Below are sample questions representative of the exercises included on this worksheet and related 8.92 Source Evaluation Authority, Purpose, and Evidence skill assessments:

Problem 1Difficulty: Mastery

Claim: "a new noise ordinance in Riverton increased unemployment." You locate: • A campaign ad repeating the claim. • A news story quoting the campaign ad. • A link in the story that goes back to the campaign website. No independent data source is provided.

What is the BEST description of the evidence situation?

AIt’s peer-reviewed because it appears in the news.

BIt’s a strong chain of evidence because multiple items mention it.

CIt’s a primary data source because it is online.

DIt’s circular sourcing: the sources all trace back to the same interested party, so the claim isn’t independently supported.

Solution & Explanation:Multiple mentions don’t equal independent evidence. If every citation loops back to the same original interested source, you still need an outside dataset or neutral reporting to verify the claim.

Problem 2Difficulty: Mastery

A research summary claims: "a food safety recall notice in Silver Valley saves 25% energy." It reports results but refuses to share the dataset or calculation steps, saying they are "proprietary." No independent evaluation is cited.

Which limitation MOST weakens the evidence?

AThe summary is shorter than a full paper.

BThe summary uses a percent sign.

CThe results cannot be independently checked or reproduced because the data and methods are not shared.

DThe summary is written in complete sentences.

Solution & Explanation:Good evidence can be verified. If others can’t see the data or methods, they can’t confirm the result, so the claim deserves extra skepticism and independent corroboration.

Problem 3Difficulty: Mastery

A graph shows that as a new bike lane proposal expanded in Elmview, "complaints" also rose. The post concludes: "Therefore a new bike lane proposal caused the rise." It does not mention population growth or changes in reporting.

What is the MOST important problem with the conclusion?

AIt assumes causation from correlation without ruling out other explanations (confounders).

BIt is posted online.

CIt includes a graph.

DIt uses the word therefore.

Solution & Explanation:Two trends moving together doesn’t prove one caused the other. You must consider other factors (population, reporting changes, unrelated events) and look for stronger causal evidence.
