Samuel teaches at a high school in one of the biggest cities in the United
States. His students come from diverse family backgrounds. Samuel observes
that the best students in his class are from homes where parental supervision
is minimal. The parents of the bottom five students are the most involved, by
a large margin. There are 24 students in his class. Samuel is going to write an
academic paper based on his students' family backgrounds and academic
performance. The paper will argue that parental involvement is not an
important factor in academic success.
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.

- B. Intelligence and instinct are not clearly distinct in the context.

Which of the following statements most closely correlates with the definition of the term working man?
- A. A working man is not someone who works for institutions or corporations, but someone who is well-versed in the workings of the soul.
- B. A working man is someone who is probably not involved in social activities because the physical demand for work is too high.
- C. A working man is someone who works for wages among the middle class.
- D. The working man has historically taken to the field, to the factory, and now to the screen.
Correct Answer: D
Rationale: Option D provides a succinct summary of the historical shifts in the type of work commonly associated with the 'working man.' It references how the working man has transitioned from agricultural fields to factories and eventually to modern society's dependence on technology, represented by the 'screen.' This progression highlights the evolution of labor and the changing landscape of work over time. Choices A, B, and C do not accurately capture the essence of a working man's historical journey through various types of labor and the societal changes that have influenced it.
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 part of the appendicular skeleton?
- A. skull
- B. clavicle
- C. scapula
- D. pelvic bone
Correct Answer: A
Rationale: The correct answer is A, 'skull.' The skull is part of the axial skeleton, not the appendicular skeleton. The axial skeleton, which includes the skull, vertebrae, and ribs, is located down the center of the body and protects vital organs such as the brain and heart. On the other hand, the appendicular skeleton consists of bones of the arms, legs, and the bones that attach these limbs to the axial skeleton. Choices B, C, and D (clavicle, scapula, pelvic bone) are part of the appendicular skeleton as they form the bones of the limbs and girdles that connect the limbs to the axial skeleton.
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.
In the United States, the foreign language requirement for high school graduation is decided at the state level. This means the requirement varies, with some states deciding to forego a foreign language requirement altogether (www.ncssfl.org). It is necessary that these states reconsider their position and amend their requirements to reflect compulsory completion of a course of one or more foreign languages. Studying a foreign language has become increasingly important for the global economy. As technology continues to make international business relations increasing easy, people need to keep up by increasing their communication capabilities. High school graduates with foreign language credits have been shown to have an increased college acceptance rate. In addition, students who have mastered more than one language typically find themselves in greater demand when they reach the job market. Students who did not study a foreign language often find themselves unable to obtain a job at all.
Which of the following statements represents the best summary of the claims made in this passage?
- A. Studying a foreign language is important if you want to graduate from high school and get a job.
- B. Studying a foreign language is important for the global economy because of the technological advances that have made international communication easier.
- C. Studying a foreign language is important for the global economy, college acceptance rates, and becoming a sought-after candidate in the job market.
- D. Studying a foreign language is important for college acceptance rates and obtaining a job after college.
Correct Answer: C
Rationale: Option C best summarizes the claims made in the passage. Studying a foreign language is highlighted as important for the global economy, college acceptance rates, and becoming a sought-after candidate in the job market. The passage emphasizes that as technology advances, communication across borders becomes crucial, making foreign language skills valuable. High school graduates with foreign language credits tend to have higher college acceptance rates. Additionally, mastering more than one language increases desirability in the job market. Option A is too narrow, focusing only on high school graduation and job prospects. Option B, while mentioning the global economy, misses the emphasis on college acceptance rates and job market desirability. Option D is also limited, as it only considers college acceptance rates and job prospects but does not cover the importance of foreign languages for the global economy.
