1. Which organ helps break down food by grinding it with your teeth?

• A. Stomach
• B. Esophagus
• C. Liver
• D. Mouth

Correct answer: D

Rationale: The correct answer is D: Mouth. The mouth is the organ that helps break down food by grinding it with your teeth. The process of chewing, also known as mastication, breaks down food into smaller pieces, making it easier to swallow and digest. The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed, such as the stomach, esophagus, and liver, do not directly participate in the mechanical breakdown of food through chewing. The stomach is responsible for further digestion through chemical processes, the esophagus is a muscular tube that helps transport food to the stomach, and the liver is primarily involved in metabolic functions and bile production.

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. Which of the following phases of mitosis is characterized by the separation of sister chromatids and their movement to opposite poles?

• A. Metaphase
• B. Anaphase
• C. Telophase
• D. Cytokinesis

Correct answer: B

Rationale: During anaphase of mitosis, the sister chromatids, which are duplicated copies of a chromosome, separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules attached to the chromatids. As a result, each pole of the cell receives a complete set of chromosomes, ensuring that the daughter cells produced after cell division will have the correct number of chromosomes. Metaphase is characterized by the alignment of chromosomes at the cell's equator, not their separation. Telophase is the phase following anaphase, where the separated chromatids reach the opposite poles and nuclear envelopes start to form around them. Cytokinesis is the final stage of cell division, where the cytoplasm is divided to form two separate daughter cells.

4. Which of the following statements represents an exaggerated claim in support of the argument presented in this passage?

• A. In the United States, the foreign language requirement for high school graduation varies depending on the state.
• B. Studying a foreign language is crucial for success in the global economy.
• C. High school graduates with foreign language credits have a higher college acceptance rate.
• D. Students who did not study a foreign language are completely unable to secure any job.

Correct answer: D

Rationale: The correct answer is D because it is an exaggerated claim to state that students who did not study a foreign language are completely unable to secure any job. While proficiency in a foreign language may enhance job prospects, it is unrealistic to suggest that not studying one would render someone unemployable. Choice A provides a factual statement about the variation in foreign language requirements, so it cannot be considered an exaggeration. Choices B and C highlight the increasing importance of foreign language skills and the benefits of having them, which are supported by trends and studies. These choices may be debatable, but they are not exaggerated claims.

5. Which of the following is not a reliable resource for a research paper?

• A. The New York Times
• B. A personal interview with a politician
• C. A medical journal
• D. Wikipedia

Correct answer: D

Rationale: Wikipedia is not a reliable source for a research paper due to its open editing format, which may lead to inaccuracies, bias, and lack of authority. While it can be a good starting point for research and general information, it is crucial to verify information from Wikipedia with more academic and reputable sources like peer-reviewed journals, books, or official websites. The New York Times, a personal interview with a politician, and a medical journal are generally considered reliable sources for research papers. The New York Times is a reputable newspaper, personal interviews can provide valuable firsthand insights, and medical journals undergo rigorous peer review processes to ensure accuracy and reliability.
