After reading the paragraph below, answer the questions that follow. researchers set up a study to determine whether large doses of a nutritional supplement would shorten the length of time it takes to recover from a cold. three thousand volunteers were split into two groups. for two weeks, members of group a took 3,000 mg of the supplement daily. group b received 3,000 mg of a placebo (sugar pill), at the end of the two-week period, the researchers inserted live cold viruses directly into the noses of all the volunteers. the volunteers in both group a and group b continued to take their daily pills. all the volunteers got colds, and there was no significant difference in the length of time the colds lasted. which was the experimental group?
a. group a only
b. group b only
c. all 3,000 volunteers

A. Group A only

Explanation:

The experimental group was group A, on the other hand, the control group was group B.

An experimental group is a set of people that receives treatment in an experiment, supplement daily in this case.

In every experiment, there is a test of subjects that are exposed to the treatment that is being studied called experimental group. But also, they must perform the same experiment with another test of subjects not exposed to the new treatment called control. In other to see if they are any differences between the two of them.

In this case, the treatment supplement daily was given to the group A. And the placebo or sugar pill with nothing in it was given to the group B to compare and confirm if the treatment actually works.

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
