Q #1: In order to determine the effects of energy drinks on women's running speed, researchers gave 300 women an energy drink and then recorded the time it took each of them to run 2 miles. After collecting the results, researchers concluded that energy drinks increase the speed of running in Which of the following further tests would best help to support this conclusion?

A. Repeat the same experiment, using 300 men

B. Repeat the experiment giving half of the women water and the other half the energy drink

C. Repeat the experiment giving the women two different energy drinks

D. Repeat the experiment, having half of the women run 2 miles and the other half run 5 miles

Answer Explanation

Conducting the experiment with half the women taking water and the other half taking an energy drink creates a study and experimental group, which can allow for comparison and conclusion. The researchers can compare the effects of the energy drink directly with a baseline, and this helps to establish a cause-and-effect relationship and provides stronger evidence to support their conclusion.

A. Oxygen, atomic number 8

B. Fluorine, atomic number 19
