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.

The Bill of Rights is the first 10 Amendments to the Constitution. It spells out Americans’ rights in relation to their government. It guarantees civil rights and liberties to the individual—like freedom of speech, press, and religion.

John Paul Jones (born John Paul; July 6, 1747 – July 18, 1792) was the United States' first well-known naval commander in the American Revolutionary War. He made many friends[1] and enemies—who accused him of piracy—among America's political elites, and his actions in British waters during the Revolution earned him an international reputation which persists to this day. As such, he is sometimes referred to as the "Father of the American Navy" (a sobriquet he shares with John Barry and John Adams[2]).
Jones was born and grew up in Scotland, became a sailor, and served as commander of several British merchant ships. After having killed one of his crew members with a sword, he fled to the Colony of Virginia and around 1775 joined the newly founded Continental Navy in their fight against Britain in the American Revolutionary War. He commanded U.S. Navy ships stationed in France and led one single assault on England, which resulted in a failure, and few on British merchant ships. Left without a command in 1787, he joined the Imperial Russian Navy and obtained the rank of rear admiral.Explanation:
