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.

Correct Answer: D

Rationale: The correct answer is D because the story describes the sequence of events after adopting the dog. After bringing Robin home, the sequence includes confirming her health with a physical exam, buying supplies, installing a dog run, and then taking her to the vet. Enrolling her in obedience classes is mentioned to start the following week, making it the next logical step. Therefore, the detail about the dog's next obedience class is not out of sequence. Choices A, B, and C are all in the correct sequence according to the events described in the story.

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.

Correct Answer: C

Rationale: The logical conclusion that can be derived from the announcement is that the library has added the fee to discourage patrons from spending too long on the computers. This conclusion is supported by the fact that the library is limiting computer usage to 30 minutes and implementing a fee for extended use. Choice A is incorrect because there is no indication in the announcement that the library plans to purchase more computers. Choice B is incorrect as there is no mention of budget cuts or using the fee to compensate for them in the announcement. Choice D is incorrect as there is no information in the announcement about the library covering its Internet service costs by passing on the fee to patrons.

Correct Answer: D

Rationale: Shiloh occurred earlier than the other battles listed. Shiloh took place in April 1862 during the American Civil War, making it the earliest battle among the options provided. Cold Harbor occurred in June 1864, Chancellorsville in May 1863, and Atlanta in July-September 1864. Therefore, Shiloh is the correct answer. Choice A (Cold Harbor) is incorrect because it happened after Shiloh. Choice B (Chancellorsville) is incorrect because it occurred after Shiloh. Choice C (Atlanta) is also incorrect as it took place after Shiloh.
