Answer:
10
Explanation:
In 2003, the U.S. Environmental Protection Agency (EPA) proposed that in determining any risk, regulators should assume children have 10 times the exposure risk of adults to cancer-causing chemicals. Some health scientists contends that these guidelines are too weak. They suggest that, to be on safe side, we should assume that the risk of harm from toxins is 100 times that of adults. Others support doing this on ethical grounds, they say it is wrong not to give children much greater protection from harmful chemicals in the environment.

Qualitative research is done to obtain or which aims at expanding and gaining knowledge by asking basic question research participants related to the subjects.
