In the homeowners' group chat, a neighbor recommends a certain early childhood education institution: "The advertisement says that ten celebrities send their children to classes there. This is the best early childhood education institution, and our family is also planning to enroll." You want to verify before deciding. Which of the following evidence most directly supports the claim that "this is the best institution"?

Answer: A

• AComparative data with similar institutions in the same city regarding teacher qualifications, course effectiveness, safety records, and prices.✓ Correct. "Best" is a comparative judgment, and it only makes sense when compared along the same dimensions with similar institutions. This is the missing evidence needed to establish the conclusion.
• BMore photos and videos of celebrities sending their children to attend classes; the larger the sample, the more credible the conclusion.✗ Wrong because it expands the sample on an irrelevant dimension: no matter how many celebrities there are, it cannot answer whether the institution is "best." This essentially relies on celebrity endorsement fallacy.
• CPublic records showing that the celebrities' children have attended for a long time without transferring, indicating high parental satisfaction.✗ Wrong because it shifts the judgment dimension: duration of attendance and loyalty do not equal superior teaching outcomes, and cannot support the comparative conclusion of "best."
• DChecking whether the celebrities received endorsement fees; if they did, it shows the institution is actually not good.✗ Wrong because it appeals to motive: whether they were paid cannot infer quality, using motive instead of evidence can neither confirm nor refute the conclusion.
