1. Which of the following is an example of a secondary source that would be used in a documentary about World War I?

• A. an essay by a historian about the lasting effects of the war
• B. photographs of military equipment used in the war
• C. a recorded interview with a veteran who fought for the US Army
• D. letters written by soldiers to their families

Correct answer: A

Rationale: An essay by a historian about the lasting effects of the war is an example of a secondary source as it provides analysis and interpretation of primary sources like official documents, photographs, and letters. It offers a perspective that is based on research and not directly involved in the events, making it a valuable resource for understanding the historical context of World War I. Choice B, photographs of military equipment, is a primary source as it provides direct visual evidence from the time period. Choice C, a recorded interview with a veteran, is also a primary source as it offers firsthand accounts from someone directly involved in the events. Choice D, letters written by soldiers, are primary sources that offer insights into the personal experiences of individuals during the war.

2. Using the same reasoning as that in the passage, an automobile with eighteen wheels does what to the following hypothesis: 'All automobiles have only four wheels'?

• A. It proves the hypothesis.
• B. It raises the hypothesis's probability.
• C. It disproves the hypothesis.
• D. It decreases the hypothesis's probability.

Correct answer: D

Rationale: An automobile with eighteen wheels contradicts the hypothesis that 'All automobiles have only four wheels.' This contradiction reduces the probability that the hypothesis is true. The hypothesis is not proven by the presence of an eighteen-wheel automobile, nor does it raise the probability of the hypothesis being true. Instead, it directly challenges the hypothesis, leading to a decrease in its probability of being correct.

3. What does the following sentence most nearly mean? 'The preparatory instars of such insects are aquatic; the adult instar is aerial.'

• A. The volume of water is necessary for preparing the insect for transition rather than the volume of the air.
• B. The insect's body is shaped like a star in both water and air.
• C. The stage of preparation between molting occurs in water, while the final stage happens in the air.
• D. These insects first breathe in water through gills and then continue to use the same organs to breathe in the air.

Correct answer: C

Rationale: The sentence indicates that the insects undergo different stages of development, with the preparatory instars being aquatic and the adult instar being aerial. This highlights the adaptability of these insects to different environments. Choice A is incorrect as it focuses on the volume of water and air rather than the stages of development in different environments. Choice B is unrelated to the content of the sentence and does not capture the meaning accurately. Choice D is incorrect as it specifically mentions breathing through gills, which is not explicitly stated in the sentence. Therefore, choice C is the best interpretation of the sentence.

4. What is the main point of dispute between the politicians?

• A. Spending on social welfare programs increases the national debt.
• B. Certain classes of people rely on social welfare programs to meet their basic needs.
• C. Certain classes of people would be irreparably harmed if the country failed to provide a social welfare program.
• D. All of the country's leaders have bootstrapped their way to the top.

Correct answer: B

Rationale: The main point of dispute between the conservative and liberal politicians is about whether certain classes of people rely on social welfare programs to meet their basic needs. The conservative politician believes that no citizens truly need government assistance and that it only makes things easier, while the liberal politician argues that various groups, such as immigrants, single mothers, and the elderly, require a safety net for basic necessities. Choice A is incorrect as it refers to the impact on national debt, which is not the primary point of dispute. Choice C is incorrect as it discusses the consequences of failing to provide social welfare programs, not the main point of disagreement. Choice D is irrelevant as it talks about the backgrounds of the country's leaders, which is not the focus of the dispute between the politicians.

5. Which of the following is NOT mentioned by the author as a reason to visit Carl’s Car Depot?

• A. They are offering lifetime warranties on new cars.
• B. The sale will only last one day.
• C. They have the lowest prices in town.
• D. They are offering no money down and low monthly payments.

Correct answer: A

Rationale: The author does not mention that Carl's Car Depot is offering lifetime warranties on new cars as a reason to visit. The mentioned reasons include the one-day sale, lowest prices in town, and the offering of no money down and low monthly payments. The extract clearly states that the focus is on the one-day sale, low monthly payments, and the lowest prices available, but there is no mention of lifetime warranties as a reason to visit.
