Which definition most closely relates to the usage of the word moult in the passage?
- A. An adventure of sorts, especially underwater
- B. Mating act between two insects
- C. The act of shedding part or all of the outer shell
- D. Death of an organism that ends in a revival of life
Correct Answer: C
Rationale: The definition that most closely relates to the usage of the word 'moult' in the passage is the act of shedding part or all of the outer shell. The passage mentions how some insects remain under water until they are ready to undergo their final moult and attain the winged state. This process involves shedding their old skin or exoskeleton to transition from the aquatic larval stage to the aerial adult stage. Choices A, B, and D are incorrect because they do not align with the specific context provided in the passage. Choice A talks about an adventure underwater, which is unrelated to the biological process of moulting. Choice B refers to a mating act between insects, which is not the focus of the passage. Choice D discusses the death of an organism leading to a revival of life, which is not connected to the moulting process described in the passage.

Which of the following statements least supports the argument that the American economy is healthy?
- A. The United States' Gross Domestic Product (GDP) increased by two percent last year.
- B. Unemployment is the lowest it has been in over a decade due to job creation.
- C. Average household income just hit a historical high point.
- D. The output of the United States' manufacturing sector decreased.
Correct Answer: D
Rationale: The correct answer is D because a decrease in the manufacturing sector is usually considered a negative indicator for the economy, as it may suggest a decline in production or demand for goods. Choices A, B, and C all provide positive signs for a healthy economy: an increase in GDP reflects economic growth, low unemployment rates indicate a strong job market, and rising household income signifies improved financial well-being for families.
Which of the following events occurred most recently?
- A. Helped found National Geographic Society
- B. Developed a metal detector
- C. Moved to Canada
- D. Invented the telephone
Correct Answer: D
Rationale: Alexander Graham Bell invented the telephone after founding the National Geographic Society and developing a metal detector. Therefore, inventing the telephone is the most recent event among the options provided. Moving to Canada occurred earlier than the invention of the telephone, and helping to found the National Geographic Society also happened before the invention of the telephone.
What is the main idea of the second paragraph?
- A. One hairy monkey proves the hypothesis 'All monkeys are hairy.'
- B. The same piece of evidence can both confirm and disconfirm a hypothesis.
- C. Confirming and disconfirming evidence affect hypotheses differently.
- D. The scientific method is not a failsafe method for arriving at objective truth.
Correct Answer: C
Rationale: The main idea of the second paragraph is that confirming and disconfirming evidence can affect hypotheses differently, as stated in the passage - 'Single pieces of evidence then, seem to affect a given hypothesis in radically different ways.' Choice A is incorrect because the paragraph discusses how single pieces of evidence affect hypotheses, not that one hairy monkey proves a hypothesis. Choice B is incorrect as the paragraph focuses on the different effects of evidence on hypotheses, rather than its ability to confirm and disconfirm simultaneously. Choice D is incorrect as the paragraph does not primarily discuss the scientific method's failings but rather the impact of evidence on hypotheses.
What is the best summary of the instructor's motive in sending the email to the students?
- A. Expressing concern about students' grades and emphasizing the importance of being worried.
- B. Recognizing the low exam scores and the need to adjust the grading plan to help students improve.
- C. Explaining the purpose of a group project and how it benefits students working together.
- D. Stating the strict grading policy set at the beginning of the semester.
Correct Answer: B
Rationale: Answer choice B is the correct summary of the instructor's motive in sending the email to the students. The passage mentions that the instructor acknowledged the low exam scores, including a high failure rate and the need to reconsider the grading plan for the semester. This indicates that the instructor wants to adjust the grading plan to provide students with an opportunity to improve their scores. Choice A is incorrect as it focuses on expressing concern rather than on adjusting the grading plan. Choice C is unrelated as it discusses the purpose of a group project. Choice D is also incorrect as it mentions the strict grading policy set at the beginning of the semester, which is not the main focus of the email sent by the instructor.
With which of the following statements would the author most likely agree?
- A. There is no real mystery about the Bermuda Triangle because most events have reasonable explanations.
- B. Researchers are wrong to expand the focus of the Triangle to the Azores, as this increases the likelihood of accidents.
- C. The official statement of 'causes or reasons unknown' in the loss of the Navy planes was a deliberate concealment from the Navy.
- D. Reducing the legends about the mysteries of the Bermuda Triangle will help to reduce the number of reported accidents or shipping losses in the region.
Correct Answer: D
Rationale: The author would most likely agree with the statement that reducing the legends about the mysteries of the Bermuda Triangle will help to reduce the number of reported accidents or shipping losses in the region. This aligns with the perspective that many events in the Bermuda Triangle can be explained logically and that dispelling myths and legends can lead to a more accurate understanding of the phenomena occurring in the area. Choice A is incorrect because the author acknowledges that the Bermuda Triangle has sparked interest due to unexplained events. Choice B is incorrect as expanding the focus of the Triangle to the Azores is not associated with an increase in accidents, according to the author. Choice C is incorrect as the author does not suggest a deliberate concealment but rather points towards logical explanations for the events in the Bermuda Triangle.
