Question

Which of these statements is NOT testable?

A) Nurses who work at doctors' offices are very nice
B) Changing the shape of a paper airplane may affect its flight
C) The amount of water a plant receives may affect its growth
D) None of the above

Answer 1

The statement 'Nurses who work at doctors' offices are very nice' is not testable because it is subjective and not quantifiable.

Step-by-step explanation:

Among the statements presented, the one that is NOT testable is: "Nurses who work at doctors' offices are very nice." This statement cannot be easily tested because it is subjective; what constitutes "very nice" can vary greatly from person to person and is not quantifiable or consistently measurable. On the other hand, statements about the effect of changing a paper airplane's shape on its flight or the impact of water on plant growth are testable because they can be measured and observed objectively.
