A company was testing a new drug they thought would help decrease the risk of transmitting viruses from mother to fetus. In an experiment to test the compound, a worker gave 400 pregnant rats a small dose of the experimental drug and inoculated each with a type of virus known to cause disease n rats. 400 additional pregnant rats were only given only the virus. 203 of the rat pups born to the females that received both the virus and the drug showed no symptoms of the disease; 207 rat pups born to virus-only females showed symptoms. From this test,we can best conclude_____________.

That the drug seems to have little effect on viral transmission at the dosage given
- C.
Nothing, because no control group was used in the test of the drug

Radon is a radioactive gas that seeps into homes from the soil. It is thought to be a leading cause of lung cancer. A research team investigates this theory. They gather large amounts of data on basement radon concentrations and lung cancer rates and conclude that the more radon there is, the more likely is lung cancer. After the study is published, other researchers criticize it by asserting that the studied neighborhoods with higher radon concentrations may have a higher percentage of old people and higher percentage of cigarette smokers than the low-radon neighborhoods. Both advance age and cigarette smoking increase the risk of lung cancer. This criticism, if correct, shows that the radon study suffered from _______________________.
- A.
Lack of replication

A small sample size

An unfalsifiable hypothesis
- E.
Nonsystematic observation
