Scientific experiments must be able to be repeated by multiple scientists to verify the results that are obtained. 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?

The example of a scientific question that could be used to create an easily reproducible experiment is:

b. Does the mass of a rocket affect the distance it can travel?

Explanation: The question "Does the mass of a rocket affect the distance it can travel?" is a question which is reproducible because it allows scientists to work on different materials which would affect the distance which a rocket travels.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

b. cronkite, a trusted television personality, declared that the war was unwinnable and told the american people that the government had better find a way out

even though it went against everything the news anchors typically stood for, cronkite voiced an opinion and took a stance, telling the us that there was no way they were going to win, the war was going to end in a stalemate.
