An adult skeleton had 206 bones. The skeleton has two major divisions: the axil skeleton and the appendicular skeleton. The axial skeleton, which consists of 80 bones including the skull, vertebrae, and rib, is located down the center of the body. The axial skeleton protects vital organs such as the brain and heart. The appendicular skeleton consists of 126 ones of the arms, legs, and the bones that attach these bones to the axial skeleton. The appendicular skeleton includes the scapulae (shoulder blades), clavicles (collarbones), and pelvic (hip) bones.
Which of the following bones is not associated with the leg?
- A. femur
- B. tibia
- C. patella
- D. radius
Correct Answer: D
Rationale: The correct answer is D, radius. According to the passage, the radius is a bone in the lower arm, not in the leg. The femur, tibia, and patella are bones associated with the leg. The femur is the thigh bone, the tibia is the shin bone, and the patella is the kneecap. Therefore, the radius is the only bone among the options that is not associated with the leg.

Which of the following bones are located in the hand?
- A. fibula
- B. metacarpals
- C. metatarsals
- D. ulna
Correct Answer: B
Rationale: The correct answer is B, metacarpals. The metacarpals are the bones located in the hand, making up the palm and connecting to the fingers (phalanges) and wrist bones (carpals). The fibula and ulna are located in the leg and arm respectively, while the metatarsals are found in the foot. The axial skeleton consists of bones down the center of the body, including the skull, vertebrae, and ribs, while the appendicular skeleton includes bones of the arms, legs, and their attachments to the axial skeleton.
Eventually, his son King Charles II would be crowned, and this Charles is believed to have converted secretly to the Catholic Church. Charles II died without a legitimate heir, and his brother James ascended to the throne as King James II. James was recognized to be a practicing Catholic, and his commitment to Catholicism would prove to e his downfall. James's wife Mary Beatrice lost a number of children during their infancy, and when she became pregnant again in 1687 the public became concerned. If James had a son, that son would undoubtedly be raised a Catholic, and the English people would not stand for this. Mary gave birth to a son, but the story quickly circulated that the royal child had died and the child named James's heir was a foundling smuggled in. James, his wife, and his infant son were forced to flee; and James's Protestant daughter Mary was crowned the queen. In spite of a strong resemblance to the king, the young James was generally rejected among the English and the Lowland Scots, who referred to him as "the Pretender." But in the Highlands the Catholic princeling was welcomed. He inspired a group known as Jacobites, to reflect the Latin version of his name. His own son Charles, known affectionately as Bonnie Price Charlie, would eventually raise an army and attempt to recapture what he believed to be his throne. The movement was soundly defeated at the Battle of Culloden in 1746, and England and Scotland have remained ostensibly Protestant ever since.
Which of the following best describes the author's intent in the passage?
- A. to persuade
- B. to entertain
- C. to express feelings
- D. to inform
Correct Answer: D
Rationale: The author's intent in the passage is to inform the reader about the historical events surrounding King James II, his family, and the succession of the English throne. The passage provides a detailed account of the lineage, religious affiliations, and the political implications of James II and his descendants. It does not aim to persuade, entertain, or express feelings, but rather presents a factual narrative of historical events. Therefore, choice D, 'to inform,' is the correct answer. Choices A, B, and C are incorrect because the passage is focused on presenting historical information rather than persuading, entertaining, or expressing emotions.
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.
A synonym for disconfirmed would be:
- A. proven
- B. dissipated
- C. distilled
- D. disproven
Correct Answer: D
Rationale: The word 'disconfirmed' can be understood by breaking down 'disconfirm,' where 'dis' indicates 'not' and 'confirm' means 'to prove.' Therefore, 'disconfirmed' means 'not proven,' which aligns with the meaning of 'disproven.' In the given passage, it is mentioned that evidence can disprove a hypothesis, not necessarily prove it. This supports the synonymity between 'disconfirmed' and 'disproven.'
Choice A ('proven') is incorrect because 'proven' is the opposite of 'disconfirmed.'
Choice B ('dissipated') is incorrect as it means to disappear or scatter, not related to disproving a hypothesis.
Choice C ('distilled') is incorrect as it means to purify a liquid through heating and cooling, not related to proving or disproving hypotheses.

What is the author's likely purpose in writing this passage about Queen Victoria?
- A. To persuade the reader to appreciate the accomplishments of Queen Victoria, especially when placed against the failures of her forebears.
- B. To introduce the historical impact of the Victorian Era by introducing the queen who gave that era its name.
- C. To explain how small events in history led an unlikely princess to become the queen of England.
- D. To indicate the role that King George III's many sons played in changing the history of England.
Correct Answer: C
Rationale: The author's likely purpose in writing this passage about Queen Victoria is to explain how small events in history led to an unlikely princess becoming the queen of England. The passage details the series of events that changed the course of British succession and highlights Victoria's unexpected path to the throne. It focuses on the historical process that resulted in her becoming queen, rather than persuading the reader to appreciate her accomplishments, introducing the Victorian Era as a whole, or discussing the role of other historical figures like King George III's sons.

According to the food chain diagram, which of the following animals has no natural predators?
- A. Vulture
- B. Cobra
- C. Mongoose
- D. Aardvark
Correct Answer: B
Rationale: The correct answer is B, Cobra. In the food chain diagram, cobras are often considered apex predators, meaning they are at the top of the food chain and do not have natural predators. Vultures (choice A), although scavengers, may face competition but not direct predators. Mongooses (choice C) are known for preying on snakes, including cobras, and aardvarks (choice D) are part of the food chain and have predators like lions and hyenas.
