Study guide: Context Makes Claims Checkable
Evaluate source purposes, geographic scope, constrained choices, and claim wording.
Ideas to explain in your own words
- Use a creator’s role and purpose to interpret what a source can establish.
- Detect when different spatial definitions make two totals incomparable.
- Use supplied constraints and preferences to explain a fictional resource choice.
- Evaluate a universal claim against complete supplied fictional records.
Watch your reasoning
- A regional ranking requires both a measure and comparison cases. The other questions do not test the advertised superlative.
- The dates and measured category match; only B includes Block 4, whose six stalls explain the difference.
- The caption project is feasible and ranks second. Feasibility of alternatives does not let the committee complete them all under a one-project rule.
- E belongs to the stated six-renter group and reports not using the board during the same week, making a relevant counterexample.
A worked review example
Read a record in its context: The notebook supports a count of 40 stalls rented, assuming the record is complete. The flyer’s “busiest” claim would need comparable attendance or trade data from other markets; a bread queue alone cannot provide that. Compare Map Boundaries Before Comparing Totals: “Both maps report 12 rented stalls in Blocks 1–3 on October 1. B includes Block 4’s six, giving 18 within its larger district boundary. These are same-date spatial totals, not a measured time increase.” Compare an Allocation and Its Opportunity Cost: “All projects fit, so the committee chooses the eight-hour catalog. Caption revision is the next-best feasible alternative it forgoes. Inventory is also forgone, but it is not the next-best alternative under the supplied ranking.” Test a Claim and a Counterexample: “Every renter is not supported: E explicitly reports not using the board. The stipulated complete log records four of six listed renters using it this week. A narrower claim is that four listed renters are recorded users, conditional on the log’s supplied completeness.”
Make a practice plan
- Try the supplied lesson problems without looking at the answers.
- Compare your method with the worked examples and explain any correction.
- Use the new review cases, then complete the transfer task on paper or in your own document.
