Which of the following can be logically inferred from the passage?

Correct Answer: D

Rationale: The correct answer is D. It can be inferred from the passage that historians have difficulty definitively pinpointing Viking historical events. The passage highlights the uncertainty around Leif Erikson's birth year, conflicting accounts of interactions with natives, and the lack of clarity regarding specific events in Viking history. Choices A, B, and C are incorrect. There is no indication in the passage that the Vikings disliked exploring the New World; Leif Erikson's banishment did not directly lead to his exploration of Canada but rather his desire to spread Christianity and find new lands; and there is no mention of Leif Erikson not sharing his stories with the King of Norway.

Correct Answer: D

Rationale: According to the food chain diagram, mongooses are consumers that feed on smaller animals like mice, making choice D the correct answer. Shrub (choice A) is a plant and not a typical food for mongooses. Aardvark (choice B) is a large mammal that is not a primary food source for mongooses. Vulture (choice C) is a scavenger bird that typically feeds on carrion, not a preferred food for mongooses.

Correct Answer: D

Rationale: The event that occurred fourth on the timeline was starting a school for the deaf. Looking at the provided extract, we can see that the order is significant when discussing a timeline. Out of the given events, founding a school for the deaf would come fourth in chronological order. 'Helped found National Geographic Society,' 'Developed a metal detector,' and 'Moved to Canada' would precede starting a school for the deaf in a chronological timeline, making them incorrect choices.

Correct Answer: D

Rationale: Alexander Graham Bell invented the telephone after founding the National Geographic Society and developing a metal detector. Therefore, inventing the telephone is the most recent event among the options provided. Moving to Canada occurred earlier than the invention of the telephone, and helping to found the National Geographic Society also happened before the invention of the telephone.

Correct Answer: B

Rationale: The best conclusion to an essay about civil rights activist Rosa Parks should reflect her significance and impact. Choice A, while true, focuses on a specific event rather than summarizing her broader influence. Choice C, though factual, is not a strong conclusion as it does not capture the essence of her legacy. Choice D, although related to her actions, is not as encompassing as Choice B. Option B is the most suitable conclusion as it highlights Rosa Parks' heroism, emphasizing how she inspired change and symbolized the power of ordinary individuals in making a difference.
