Why is scientific testing weak if a claim can be adjusted to explain every possible outcome?

Answer and explanation

Correct answer: No outcome would count against the claim

Direct answer: Option A, no outcome would count against the claim. A scientific claim is useful only when it makes a clear prediction that could possibly be shown false. If a person changes the claim after every result so that every result is said to support it, the claim cannot be seriously tested. Step by step: state the claim before collecting results; identify what result would support it and what result would challenge it; compare the actual result with those predictions; revise or reject the claim if appropriate. Option A is correct because a claim that explains every possible outcome is not vulnerable to evidence. Option B is wrong because flexible explanations do not make every result more accurate. Option C is wrong because sample representation depends on sampling method, not on changing a claim. Option D is wrong because a hypothesis does not become a law merely by explaining outcomes. Memory cue: a scientific claim must be able to lose.
