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.

How are Hypotheses Confirmed? Most scientists agree that while the scientific method is an invaluable methodological tool, it is not a failsafe method for arriving at object ruth. It is a debatable, for example, whether a hypothesis can actually be confirmed by experience. When a hypothesis is of the form "All x and y," it is commonly believed that a piece of evidence that is both x and y confirms the hypothesis. For example, for the hypothesis "All monkeys are hairy," a particular monkey that is hairy is thought to be a confirming piece of evidence for the hypothesis. A problem arises when one encounters evidence that disproves a hypothesis: while no scientist would argue that one piece of evidence proves a hypothesis, it is possible for one piece of evidence to disprove a hypothesis. To return to the monkey example, one hairless monkey out of one billion hairy monkeys disproves the hypothesis "All monkeys are hairy." Single pieces of evidence then, seem to affect to given hypothesis in radically different ways. For this reason, the confirmation of hypotheses is better described as probabilistic. Hypotheses that can only be proven or disproven based on evidence need to be based on probability because sample sets for such hypotheses are too large. Int eh monkey example, every single monkey in the history of monkeys would need to be examined before the hypothesis could be proven or disproven. By making confirmation a function of probability, one may make provisional or working conclusions the tallow for the possibility of given hypothesis being disconfirmed in the future. Int he monkey case, then, encountering a hairy monkey would slighting rise the probability that "all monkeys are hairy," while encountering a hairless monkey would slightly decrease the probability that "all monkeys are hairy." This method of confirming hypotheses is both counterintuitive and controversial, but it allows for evidence to equitably affect hypotheses and it does not require infinite sample sets for confirmation or disconfirmation.
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.
Stories have been a part of the world since the beginning of recorded time. For centuries before the invention of the printing press, stories of the world were passed down to generations through oral tradition. With the invention of the printing press, which made written material available to wide ranges of audiences, books were mass-produced and introduced into grater society. For the last several centuries, books have been at the forefront of education and entertainment. With the invention of the Internet, reliance on books for information quickly changed. Soon, almost everything that anyone needed to known could be accessed through the internet. Large printed volumes of encyclopedias became unnecessary as all of the information was easily available on the Internet. Despite the progression of the Internet, printed media was till very popular in the forms of both fiction and non-fiction books. While waiting for an appointment, enduring a several-hour flight, or relaxing before sleep, books have been a reliable and convenient source of entertainment, and one that society has not been willing to give up. With the progression and extreme convenience of technology, printed books are going to soon become a thing of the past. Inventions such as the iPad from Macintosh and the Kindle have made the need for any kind off printed media unnecessary. With a rechargeable battery, a large screen, and the ability to have several books saved on file, electronic options will soon take over and society will no longer see printed books. Although some people may say that the act of reading is not complete without turning a page, sliding a finger across the screen or pressing a button to read more onto the next page is just as satisfying to the reader. The iPad and Kindle are devices that have qualities similar to a computer and can be sued for so much more than just reading. These devices are therefore better than books because they have multiple uses. In cultural society that is part of the world and due to long-standing tradition, stories will always be an important way to communicate ideas nd provide information and entrainment. Centuries ago, stories could only be remembered and retold through speech. Printed media changed the way the world communicated and was connected, and now, as we move forward with technology, it is only a matter of time before we must say goodbye to the printed pas and welcome the digital and electronic future.
What is a secondary argument the author makes?
- A. Devices such as the iPad or Kindle are better than books because they have multiple uses.
- B. Books are still important to have while waiting for an appointment or taking a flight.
- C. Printed encyclopedias are still used and more convenient than using the Internet.
- D. With technology, there will soon be no need for stories.
Correct Answer: A
Rationale: The secondary argument made by the author is that devices such as the iPad and Kindle are superior to printed books because they offer multiple functions beyond just reading. The author mentions that these devices have qualities similar to a computer and can be used for much more than just reading, making them a more versatile option compared to traditional books. Choice B is incorrect because the author does not emphasize the importance of books for specific situations like waiting for appointments or flights. Choice C is incorrect as the author does not compare printed encyclopedias to the Internet. Choice D is incorrect as the author does not suggest that technology will eliminate the need for stories; instead, they focus on the transition from printed books to electronic devices for reading.

In his initial review, Jorgen learns that Eratosthenes is considered the first person to calculate the circumference of the earth, and that he is considered the first to describe geography as it is studied today.
To which section of the library should Jorgen go to find out more about the current applications of the sieve of Eratosthenes?
- A. 000
- B. 100
- C. 400
- D. 500
Correct Answer: D
Rationale: Jorgen should go to the 500 section of the library, which covers science and mathematics, to find out more about the current applications of the sieve of Eratosthenes. The sieve of Eratosthenes is a mathematical tool used to determine prime numbers, making the science and mathematics section the most appropriate choice. Philosophy and psychology (100), languages (400), and computer science (000) are not the primary areas where one would typically find information on the applications of this mathematical tool.
In 1889, Jerome K. Jerome wrote a humorous account of a boating holiday. Originally intended as a chapter in a serious travel guide, the work became a prime example of a comic novel. Read the passage below, noting the word/words in italics. Answer the question that follows. I felt rather hurt about this at first; it seemed somehow to be a sort of slight. Why hadn't I got housemaid's knee? Why this invidious reservation? After a while, however, less grasping feelings prevailed. I reflected that I had every other known malady in the pharmacology, and I grew less selfish, and determined to do without housemaid's knee. Gout, in its most malignant stage, it would appear, had seized me without my being aware of it; and zymosis I had evidently been suffering with from boyhood. There were no more diseases after zymosis, so I concluded there was nothing else the matter with me. Jerome K. Jerome, Three Men in a Boat
Which definition best fits the word zymosis?
- A. Discontent
- B. An infectious disease
- C. Poverty
- D. Bad luck
Correct Answer: B
Rationale: In this passage, the word 'zymosis' is described as a malady that the narrator has been suffering from since boyhood. This aligns with the definition of zymosis as an infectious disease, making option B the correct choice. Choices A, C, and D are incorrect because the passage clearly indicates that zymosis is a medical condition, not related to feelings of discontent, poverty, or bad luck.
Based upon the contextual evidence provided in the passage above, what is the meaning of the term enterprise in the third paragraph?
- A. Company
- B. Courage
- C. Game
- D. Cause
Correct Answer: A
Rationale: In the third paragraph, the term 'enterprise' is used in the context of a group of travelers embarking on a journey together. In this context, 'enterprise' refers to a company or a group of people rather than courage, game, or cause. The word 'enterprise' is commonly used to denote a business organization or company, aligning with the idea of a group traveling together for a common purpose. 'Courage' and 'cause' do not fit the context of the travelers' journey, and 'game' is unrelated to the activities described in the passage.
