Correct answer: A

Rationale: The correct answer is A. The passage mentions that explorers like Lewis and Clark were sent to the newly acquired Louisiana Territory immediately after the Louisiana Purchase. This indicates that explorers were already on their way to the region following the purchase. Choice B is incorrect as there is no direct mention of the government wanting to increase its power right after the purchase.

• B. Enrolling the dog in obedience classes.
• C. The physical exam confirming the dog's health.

• D. Plastic pollution has no impact on marine life.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage is that plastic pollution poses a significant environmental threat due to its lasting nature and difficulty in recycling. The passage highlights the challenges of recycling plastic due to its low quality when recycled, leading to pollution and environmental hazards. It mentions the presence of a large island of plastic in the Pacific Ocean, showing the severe impact of plastic pollution on the environment. Therefore, choice A is the most accurate conclusion. Choice B is incorrect as the passage mentions that plastic has many advantages despite its recycling challenges. Choice C is incorrect as the passage indicates that recycling plastic is difficult due to its low quality when recycled. Choice D is incorrect as the passage clearly states that plastic consumption by marine life like fish and birds is a reality, showing the impact of plastic pollution on marine ecosystems.

5. What is the purpose of the italicized text in the passage?

• A. To show Madame Butterfly's title
• B. To emphasize an idea
• C. To format a heading
• D. To indicate the title of the opera

Correct answer: D

Rationale: The purpose of the italicized text is to indicate the title of the opera, Madame Butterfly. In the text, 'Madame Butterfly' is italicized to highlight that it refers to the title of the opera written by Giacomo Puccini. It does not serve to show Madame Butterfly's thoughts (choice A), emphasize an idea (choice B), or format a heading (choice C). The italicization is specifically used to identify the title of the opera within the passage.
