Problem 1
Answer and explanation
Comparison with independently produced evidence that supports or challenges a claim. Credibility concerns whether a source is dependable for a particular purpose. Examine authorship, method, date, access to information, and traceable evidence. A source can be useful for one question and weak for another. Appearance alone does not settle reliability.
Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.
Problem 2
Answer and explanation
The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Problem 3
Answer and explanation
This claim is misleading. Read perspective alongside evidence. The resident directly describes a scheduling problem, but cannot count everyone with that problem. The organizer has survey results, but only from a defined invited group. Evaluate these bounded contributions rather than choose a source solely by agreement. The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Problem 4
Answer and explanation
Yes. An accurate account of a different setting may not support a claim about this trial. Explain the connection rather than assuming that authority alone makes it useful.
