Which of the following is an example of a scientific question that could be used to create an easily reproducible experiment? a. why do people like to watch television? b. does the mass of a rocket affect the distance it can travel? c. what makes the sky blue? d. does sugar or salt have a greater effect on plant growth?

I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)

but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments

Ithink the answer is b. shakeri hope im not wrong : )
