Rationale: The author would likely agree that any reason to quit smoking is valid, based on their anti-smoking stance. The provided extract extensively discusses the harmful effects of smoking, the addictive nature of nicotine, and the negative consequences associated with tobacco products. The author emphasizes the health risks, financial burden, and social implications of smoking, promoting the idea that smokers should quit for any reason that helps them stop. Choice A, suggesting that smokers should only quit cold turkey, is too restrictive and doesn't consider individual differences in quitting methods. Choice B, stating that other substances are more addictive than tobacco, is not directly supported by the extract, which highlights the extreme addictiveness of nicotine. Choice D, proposing that people who want to smoke should advocate for reduced taxes, goes against the anti-smoking stance presented in the extract, which highlights the negative impact of smoking and high tobacco prices.

In the Battle of Shiloh, fought in April 1862, the Confederates suffered around 10,700 casualties, while the Union forces had approximately 13,000 casualties. Therefore, Shiloh is the correct answer. Choice A, Cold Harbor, is incorrect because in that battle, the Confederate casualties were fewer than the Union casualties. Choices B and C, Chancellorsville and Atlanta respectively, also had more Union casualties than Confederate casualties, making them incorrect answers.

Rationale: A history textbook is the most appropriate place for the passage about George Washington because it provides historical context, factual information, and analysis of significant events related to his life and contributions. The passage discusses Washington's role in the American Revolution, his leadership during the Revolutionary War, his decision to step down after the war, his farewell address, and his views on governance and foreign affairs. This type of detailed historical content is commonly found in history textbooks. Choices B, C, and D are incorrect because an obituary focuses on a person's death and life achievements in a brief manner, a fictional story is based on imagination and creativity, and a newspaper editorial typically presents opinions on current events or issues rather than historical accounts.

Correct Answer: B

Rationale: Clothilde should look for more information in Chapter 9, 'Herbs for Immunity,' as her sister's daughter has a chronic cough. Immune-boosting herbs may help strengthen the child's immune system and potentially alleviate the cough. Chapter 9 focuses on herbs that support immune health, making it the most relevant chapter for addressing a chronic cough related to immunity. Chapters 7, 10, and 12 do not specifically focus on immunity or respiratory conditions, making them less likely to provide the information Clothilde needs.
