18 .       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 also have a higher percentage of old people and a higher percentage of cigarette smokers than the low-radon neighborhoods. Both advanced age and cigarette smoking increase the risk of lung cancer. This criticism, if correct, shows that the radon study suffered from ___________. [Hint]


19 .       Which one of the following statements is most clearly inductively derived? [Hint]


20 .       At which point is an investigator most likely to use deductive reasoning? [Hint]


21 .       Science itself is NOT capable of _____. [Hint]


22 .       Discovery science is based on _____. [Hint]


23 .       Which of these is a scientific hypothesis? [Hint]


24 .       Two garden plots were planted with corn. The soil was similar in each, and equal amounts of water were applied to each plot. One plot was fertilized, the other was not. The experimenters measured the yield as bushels of corn from each plot. The plot that did not receive the fertilizer was the _____. [Hint]


25 .       A hypothesis must be testable to be scientifically valid. Being testable means that _____. [Hint]


26 .       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 female rats a small dose of the experimental drug and inoculated each with a type of virus known to cause disease in rats. 400 additional pregnant rats were 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 _____. [Hint]


27 .       The best method for determining whether bean plants require sodium is to _____. [Hint]
