Answer:
JOHN PYNCHON commenced his mercantile career in trade with the Indians of the upper Connecticut Valley in 1652, a traffic that dominated the economic life of western Massachusetts for almost half a century after the first English settlement. He received all of his training from his father, William Pynchon, a founder of the Massachusetts Bay Colony, who made the fur trade his principal enterprise from 1636 to 1652, when he returned to England, where he spent the restof his life. The fur trade reached its height in the late fifties, and though it then declined, the son’s efforts to sustain it continued for more than a decade. The commerce of New Englanders in beaver and other peltry was of prime importance to the colonial economy, and until 1676 the Connecticut Valley was one of the few important fur-trading regions.

Answer:
C. a third variable, such as students' home environment, must have caused students to both drink more non-diet soda and engage in aggressive acts
Explanation:
From the question, we are informed about An observational study that was conducted in inner-city Boston approximately four years ago demonstrated that high-school students who consumed more than five cans of non-diet soda every week were between 9 and 15-percent likelier to engage in an aggressive act compared with counterparts who drank less non- diet soda. In this case, we can reliably conclude that a third variable, such as students' home environment, must have caused students to both drink more non-diet soda and engage in aggressive acts.
Observational studies can be regarded as studies whereby
researchers make observation about different effect of factors such as
risk factor, home, as well as environment and diagnostic test that affects the experiment. In observational studies Variables are very crucial, A variable can be anything that that is liable to change, it can change and it can be changed as well. They are factors which the observer can manipulate or control for when carrying out experiments.
