1. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.

2. What does the following sentence most nearly mean? The preparatory instars of such insects are aquatic; the adult instar is aerial.

• A. The volume of water is necessary to prepare the insect for transition rather than the volume of the air.
• B. The abdomen of the insect is shaped like a star in the water as well as in the air.
• C. The stage of preparation in between molting occurs in the water, while the final stage is in the air.
• D. These insects first breathe in the water through gills, but then use the same organs to breathe in the air.

Correct answer: C

Rationale: The sentence is describing the life cycle of certain insects where their preparatory instars occur in the water, while the adult instar lives in the air. This means that the stage of preparation between molting or shedding of the exoskeleton happens in the water, but the final stage as adults is in the air. Choice A is incorrect as it misinterprets the meaning of the aquatic and aerial environments for the insect's life stages. Choice B is incorrect as it introduces a concept of the insect's abdomen being shaped like a star, which is not mentioned or relevant to the sentence. Choice D is incorrect as it introduces information about the insects' breathing organs, which is not directly related to the sentence's meaning about their life stages.

3. 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.

4. Due to his many interests and pursuits, Eratosthenes dabbled in a variety of fields, and he is credited with a theory known as the sieve of Eratosthenes. This is an early algorithm used to determine prime numbers. To which section of the library should Jorgen go to find out more about the current applications of the sieve of Eratosthenes?

• A. 0
• B. 100
• C. 400
• D. 500

Correct answer: D

Rationale: Jorgen should go to the 500 section of the library, which is dedicated to science and mathematics. The sieve of Eratosthenes is a mathematical concept, so current applications and research related to it would be found in this section. Choice A (0) is incorrect as it is for general works. Choice B (100) is for philosophy and psychology, which are unrelated to mathematics. Choice C (400) is for languages, not mathematics.

5. Which of the following lists the author’s actions in the correct sequence?

• A. The author looked at the house on Forest Road, then at a house with a yard that was too small, then at two houses that were too small, and then finally at a house that was too expensive.
• B. The author looked at the house on Forest Road, then at two houses that were too small, then at a house with a yard that was too small, and then finally at a house that was too expensive.
• C. The author looked at two homes with yards that were too small, then a house with only one bathroom, then a house that was too expensive, and then finally the house on Forest Road.
• D. The author looked at two homes that were too small, then a house with a yard that was too small, then a house that was too expensive, and then finally at the house on Forest Road.

Correct answer: B

Rationale: The correct sequence of the author's actions based on the extract is as follows: the author looked at the house on Forest Road first, then two houses that were too small, followed by a house with a yard that was too small, and finally a house that was too expensive. Therefore, choice B correctly lists the author's actions in the given sequence. Choice A is incorrect as it reverses the order of the second and third houses visited. Choice C is incorrect as it includes a house with only one bathroom, which was not mentioned in the extract. Choice D is incorrect as it places the house on Forest Road last, whereas it was actually the first house visited.
