Question

when a student says \the puddle on the sidewalk means it rained last night,\ this is an example of: a direct observation an inference based on evidence a scientific hypothesis a proven fact

Explanation:

• Option A: Direct observation is seeing or noting a phenomenon directly. The student is not just observing the puddle but interpreting its cause, so A is incorrect.
• Option B: An inference is a conclusion drawn from evidence. The puddle (evidence) leads the student to conclude it rained (inference), so this fits.
• Option C: A scientific hypothesis is a testable prediction, not an interpretation of existing evidence, so C is incorrect.
• Option D: A proven fact is something confirmed beyond doubt. The puddle could have other causes (e.g., a sprinkler), so it's not a proven fact, making D incorrect.

Answer:

B. An inference based on evidence
