What is the mean number of people who became legal residents of the United States during this five-year period?
- A. 1,119,823
- B. 223,504
- C. 5,599,113
- D. 1,107,126
Correct Answer & Rationale
Correct Answer: A
To determine the mean number of legal residents over the five-year period, one must sum the total number of residents and divide by five. The correct calculation yields a mean of 1,119,823, reflecting the average annual influx. Option B (223,504) represents a miscalculation, likely reflecting a single year's data rather than an average. Option C (5,599,113) incorrectly totals the residents without division, suggesting a cumulative number rather than an average. Option D (1,107,126) is close but does not accurately reflect the mean, indicating a minor arithmetic error.

Which statement from the passage is an opinion?
- A. "The ill-advised rush to extract new discoveries of shale oil and natural gas is a case in point."
- B. "...if the result is polluted water and ghost towns, it is not a sustainable model."
- C. “‘Sustainability' means using natural resources responsibly so that they are available to future generations."
- D. "... to achieve sustainability a business will not view profit only in terms of dollars."
Correct Answer & Rationale
Correct Answer: A
Option A expresses a subjective viewpoint about the extraction of shale oil and natural gas, labeling it as "ill-advised." This indicates a personal judgment rather than an objective fact. In contrast, Option B presents a consequence of unsustainable practices, framing it as a logical outcome rather than an opinion. Option C defines "sustainability" in a factual manner, outlining its meaning without personal bias. Lastly, Option D describes a business approach towards sustainability, focusing on a principle rather than expressing a personal belief. Thus, A stands out as the only statement rooted in opinion.

Which technology mentioned in the passage was the first one invented by Edison?
- A. vote recorder
- B. motion-picture camera
- C. electric light bulb
- D. phonograph
Correct Answer & Rationale
Correct Answer: A
The vote recorder was the first technology invented by Edison, designed to streamline the voting process. This innovation predates his more famous inventions. The motion-picture camera (B) and electric light bulb (C) came later, showcasing Edison's evolution as an inventor. The phonograph (D), although significant in audio technology, was also developed after the vote recorder. Understanding the chronological order of these inventions highlights Edison's early contributions to technology and their impact on society.

What impact do the varying insurance rates of the Revenue Protection Plan have on farming?
- A. They maintain stable prices for certain crops.
- B. They give farmers an incentive to promote crop diversity.
- C. They ensure the steady increase of crop production levels.
- D. They give farmers an incentive to grow crops that have higher subsidies.
Correct Answer & Rationale
Correct Answer: D
The varying insurance rates of the Revenue Protection Plan incentivize farmers to cultivate crops that receive higher subsidies, as these crops can mitigate financial risks associated with farming. This option aligns with economic behavior, where farmers are likely to prioritize profitability. Option A is incorrect because insurance rates do not directly stabilize prices; they primarily provide financial protection. Option B misrepresents the incentive structure; while crop diversity is beneficial, the plan does not specifically encourage it through varying rates. Option C is misleading, as the plan does not guarantee increased production levels; it merely provides a safety net against revenue loss.

Which statement about the ratification of the 19th Amendment is based on the passage?
- A. Ratification was the result of the Seneca Falls Convention.
- B. Ratification occurred in return for the military service of women during World War I.
- C. Ratification occurred prior to the granting of voting rights to freed slaves.
- D. Ratification was the result of the accumulated efforts of women for decades.
Correct Answer & Rationale
Correct Answer: D
The ratification of the 19th Amendment was the culmination of decades of advocacy and activism by women who fought tirelessly for their voting rights, making option D the most accurate statement. Option A incorrectly attributes the ratification solely to the Seneca Falls Convention, which was just one of many events in the long struggle for women's suffrage. Option B suggests a direct exchange of military service for voting rights, which oversimplifies the complex social and political factors involved. Option C misrepresents the timeline, as the 19th Amendment was ratified after the Civil War, but the fight for voting rights for freed slaves and women evolved concurrently, not sequentially.
