1. What is the best summary of this passage?

• A. Humans can use coloration and markings on snakes to determine whether they’re venomous.
• B. Animals use coloration to hide from predators.
• C. The scarlet kingsnake and the coral snake have nearly identical markings.
• D. Venomous snakes often have bright markings, although nonvenomous snakes can also mimic those colors.

Correct answer: A

Rationale: The best summary of the passage is that humans can use coloration and markings on snakes to determine whether they're venomous. The passage discusses how snake markings serve the purpose of warning predators and helping humans identify venomous snakes by their bright coloration. Choice B is incorrect because the passage focuses on how coloration helps snakes evade predators rather than hide from them. Choice C is incorrect as it only mentions two specific snakes with similar markings, which is a minor detail compared to the main point of identifying venomous snakes. Choice D is incorrect because it only partially reflects the passage, focusing solely on the relationship between markings and venom in snakes, missing the crucial aspect of human ability to discern venomous snakes based on their coloration.

2. 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.

3. Which of the following labels best describes the previous passage?

• A. comparison essay

Correct answer: C

Rationale: The passage delves into the relationship between magnesium intake and health outcomes, highlighting how deficiencies in magnesium can lead to various health issues. It discusses how different factors, such as gastrointestinal disorders or dietary habits, can cause magnesium depletion and its subsequent effects on the body. This focus on exploring the cause-and-effect connections between magnesium levels and health conditions aligns with the characteristics of a cause and effect essay, making choice C the most appropriate. Choices A, B, and D are incorrect because the passage does not focus on comparing different concepts, providing definitions, or persuading the reader of a particular viewpoint.

4. Even without Franz Ferdinand's assassination ... Which of the following most logically completes the passage?

• A. A war between the world powers was extremely likely.
• B. World War I never would have happened.
• C. England, France, and Russia would have started the war.
• D. Austria would have started the war.

Correct answer: A

Rationale: The correct answer is A. Given the alliances and tensions at the time, the assassination was simply the trigger in an already volatile situation, making war highly likely. Choice B is incorrect because the alliances and existing tensions would likely have led to a conflict even without the assassination. Choice C is incorrect as it wrongly implies that only these three countries were involved in the conflict. Choice D is incorrect as Austria alone starting the war doesn't consider the broader context of alliances and power dynamics among the world powers.

5. 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.
