Answer:
For several months, weighing and measuring the pups every week
Explanation:
This is to control variables and keep a measurable set of data that can prove or disprove the theory they had developed, and also to isolate cases that can't be attributed to the experiment they had carried out, like puppies loosing weight due to illnesses, or behavioral factors.
Let's look at the options one by one:
<span>a. Science is never used in the wrong way by people trying to prove a point.
-this is wrong! science has been abused in many context in which people were trying to prove their (often mistaken) points: for example, it has been used to justify racism.
b. Science is able to answer society's questions about why life exists.
- this is wrong, as we still don't have an answer as to why life exists.
c. Science is intended to shape the moral views of society.
-this is not always true. Sometimes science is done just to find out new information rather than share views.
d. Science can be used to address societal issues and to inform policy.
-I think that this is the best answer! For example a scientific study in psychology can inform educational policies and a study into the effects of alcohol can inform an informational campaign about the threats of drinking.
