Question

select the correct answer. which sentence is a scientific statement?
a. there is a substance around us that cannot be detected.
b. kids should go to school for 12 years.
c. experimentation is the best way to obtain knowledge.
d. unicorns once existed on earth.
e. there are no living things on the moon.

Explanation:

• Option A: A substance that cannot be detected is untestable, so not scientific.
• Option B: This is a normative (should) statement about education policy, not scientific.
• Option C: "Best way" is a subjective opinion, not a scientific statement.
• Option D: Unicorns are mythical, and there's no evidence they existed, and the statement is not testable in a scientific way (or the claim is unfalsifiable in a scientific context as there's no way to verify it through scientific methods).
• Option E: This can be tested through scientific exploration (e.g., lunar missions, analysis of lunar samples) to check for living things, so it's a scientific statement as it's falsifiable and can be investigated with scientific methods.

Answer:

E. There are no living things on the Moon.
