Source detective
A claim. A source. Your judgment. Spot the leap the answer is making.
Classify each claim as supported, contradicted, or not established by the supplied source. These sources are fictional teaching examples. The score is a practice result, not a qualification.
The very generous opening hours
Fictional museum notice: “The museum opens Tuesday to Saturday, 10 am to 4 pm. Closed on statutory holidays.”
Claim: You can visit the museum this Sunday at noon.
Answer: contradicted.
Sunday is outside the stated opening days. The notice directly conflicts with the proposed visit.
Skill: Check dates and exceptions.
The suspicious percentage
Fictional event report: “Forty people attended in April. Sixty attended in May.”
Claim: Attendance doubled in May.
Answer: contradicted.
The increase is 20 on a base of 40: 50%. Doubling would mean 80 people.
Skill: Recalculate the number.
The bigger promise
Fictional pilot announcement: “Residents of Cedar Town can apply for the six-week pilot. The program has 30 places.”
Claim: Everyone in the province is eligible.
Answer: not established.
The source establishes eligibility for one town. It does not establish province-wide eligibility. It does not tell us whether other programs exist elsewhere.
Skill: Match the scope of the claim to the evidence.
The limit that survived the summary
Fictional workshop listing: “The beginner session costs $15. Materials are included. Advance booking is required.”
Claim: The beginner session includes materials and requires booking in advance.
Answer: supported.
Both details appear directly in the listing. This claim does not add a promise beyond the source.
Skill: Recognize a faithful summary.
The cause we do not know
Fictional shop report: “Sales increased in June. A new window display was installed in June. The street festival also took place that month.”
Claim: The new window display caused the sales increase.
Answer: not established.
The events occurred in the same month, but the report does not isolate the cause. The festival or other factors could matter.
Skill: Separate timing from causation.
The vanished qualification
Fictional usability note: “In a trial with eight volunteers, six completed the task without help.”
Claim: In this eight-person trial, six volunteers completed the task independently.
Answer: supported.
The answer preserves the small trial and the observed result. It makes no claim about every future user.
Skill: Keep the qualification attached.
