Read the passage: 'The Mariana Trench, located in the western Pacific Ocean, is the deepest point on Earth. It reaches a maximum depth of approximately 36,000 feet — deeper than Mount Everest is tall. The trench was first explored in depth by the Trieste bathyscaphe in 1960, which carried scientists Jacques Piccard and Don Walsh to the bottom.' According to the passage, who first explored the Mariana Trench's depths in 1960?

This is a SPECIFIC DETAIL question — it asks for information explicitly stated in the passage. The passage directly states: 'The trench was first explored in depth by the Trieste bathyscaphe in 1960, which carried scientists Jacques Piccard and Don Walsh to the bottom.' So the answer — JACQUES PICCARD AND DON WALSH, aboard the TRIESTE — is directly stated. DETAIL QUESTION STRATEGY: (1) Identify what specific fact is being asked about; (2) Scan the passage to find where that topic is discussed; (3) Read carefully and select the answer that matches WHAT THE PASSAGE SAYS, not what you know from outside. AVOIDING TRAPS: (1) Outside knowledge trap — you may know other ocean explorers, but the passage specifically names Piccard and Walsh; (2) Wrong detail trap — confusing the bathyscaphe name (Trieste) with the people's names; (3) 'Not mentioned' trap — Option D claims no one is specified, but the passage clearly names them; (4) Unrelated people trap — Option A names astronauts who reached the moon, not the ocean trench. KEY PASSAGE DETAILS: Location: western Pacific Ocean; Max depth: ~36,000 feet; Comparison: deeper than Mount Everest is tall; Exploration: 1960; Vessel: Trieste bathyscaphe; Explorers: Jacques Piccard and Don Walsh. ASVAB TIP: for detail questions, always find the specific line in the passage that contains the answer rather than relying on memory of the passage. The correct answer will match the passage exactly.
