Correct Answer: C

Rationale: The sentence 'Finally, we were able to settle in to enjoy the movie.' indicates the completion or conclusion of a sequence of events. The word 'finally' signals that something has been achieved or reached at the end of a series of actions or events. Choices A, B, and D do not indicate the end of a sequence but rather express different points within a series of events or actions.

Correct Answer: A

Rationale: An essay by a historian about the lasting effects of the war is an example of a secondary source as it provides analysis and interpretation of primary sources like official documents, photographs, and letters. It offers a perspective that is based on research and not directly involved in the events, making it a valuable resource for understanding the historical context of World War I. Choice B, photographs of military equipment, is a primary source as it provides direct visual evidence from the time period. Choice C, a recorded interview with a veteran, is also a primary source as it offers firsthand accounts from someone directly involved in the events. Choice D, letters written by soldiers, are primary sources that offer insights into the personal experiences of individuals during the war.

Correct Answer: B

Rationale: The correct answer is B. The author's primary purpose in writing this essay is to teach readers the difference between coral snakes and kingsnakes. The essay discusses how skin coloration and markings help snakes hide from predators and indicate whether a snake is venomous. By comparing the physical characteristics and behaviors of coral snakes and kingsnakes, the author helps readers understand how to distinguish between the two species to avoid potential dangers. Choice A is incorrect because the essay focuses more on distinguishing between snake species rather than solely on the relationship between markings and venom. Choice C is incorrect as the essay does not aim to illustrate why snakes are dangerous but rather to educate about the differences between specific snake types. Choice D is incorrect as the essay does not discuss how animals survive in difficult environments, but instead focuses on snake markings and behaviors.

Correct Answer: D

Rationale: Option D provides a sequence of events that align with the extract provided. Julia was woken up early by a lawnmower, couldn't go back to sleep, discovered she was out of regular coffee, got stuck in traffic on the way to work, found the office was out of coffee, had a lot of work to do, and decided to go home when the fire alarm went off. This sequence accurately reflects the chronological order of Julia's actions throughout the day. Choices A, B, and C do not follow a logical sequence of events based on the extract, making them incorrect.

Correct Answer: D

Rationale: Option D is the most concise summary of the passage as it encapsulates the main idea that the passage focuses on the changes in babies' senses during their first year of life. The passage explains how babies are born with sensory abilities similar to adults but highlights the significant changes that occur during the first year, particularly in vision development. While the other options touch on specific aspects mentioned in the passage, they do not capture the overall essence of the passage, which emphasizes the dynamic and transformative nature of babies' sensory experiences in their first year.
