Explanation
The anatomic bomb is a device of mass destruction used in warfare that gains its destructive force from nuclear reactions. One of its main characteristics is the formation of a mushroom-shaped cloud when it is detonated. Fissile isotopes, such as uranium-235 or plutonium-239, are necessary for its manufacture. Another important fact about atomic bombs is that they were first developed by the United States during World War II to avenge the attack on Pearl Harbor. Therefore, the correct answer is B. 235.
The complete sentence remains "To create the atomic bomb they needed uranium - 235 the most"
<u>Question 1</u>
The correct answer is: "The researchers administered a questionnaire to obtain their data without trying to influence an explanatory variable of the study".
An observational study is one in which the researcher observes the effect of a variable without manipulating the conditions that surround the exposure or the subjects who are exposed to it. In this example, he simply hands out questionaires to the 353 individuals that compose the sample drawn from the population of interest: 12-year old teenagers.
<u>Question 2</u>
The correct answer is: "a cohort study".
The researcher is interested on a population group where all the components share a common characteristic (12-year old) and therefore they all belong to the same cohort. Subsequenly, he evaluates the differences between the ones who have been exposed to the explanatory variable (having a video console in the bedroom) and those who have not.
