Read: 'In 1869, John Wesley Powell became the first person to navigate the full length of the Colorado River through the Grand Canyon. His expedition of nine men departed on May 24 and completed the passage after 98 days, having lost three men who chose to leave the canyon on foot near the end. Powell himself had lost his right arm in the Civil War, yet led the expedition from a specially built chair mounted on one of the boats.' Which detail about Powell is stated in the passage?

This is a SPECIFIC DETAIL question — the answer is directly stated in the passage and requires only that you locate the correct fact. The passage explicitly states 'Powell himself had lost his right arm in the Civil War' — this matches Option B exactly. Option A (born in Colorado) is not mentioned. Option C (second expedition) is not mentioned. Option D (appointed by the president) is not mentioned. DETAIL QUESTION STRATEGY: Go back to the passage and find the specific section about the subject of the question. Read that section carefully. Select the answer that matches the passage's exact words or meaning. The most common error on detail questions is selecting something plausible-sounding that was NOT actually in the passage — this is exactly what options A, C, and D represent. They sound like things that could be true about a historical explorer, but none appear in this passage.
