Solution
Option 1 -> The narrator blinked (showing surprise/panic, not evasion), and while he realized his job depended on his answer, the passage doesn't show him being dishonest - it says "Honestly, I didn't know."
Option 2 -> "I blinked" indicates he panicked/was caught off guard. His immediate realization that "my living depended upon my answer" shows practical, quick thinking and ability to assess situations rapidly.
Option 3 -> Blinking shows he was NOT confident. The text explicitly states "I didn't know there was any archaeology in our place" - showing lack of knowledge.
Option 4 -> Blinking shows he was NOT indifferent but concerned. Later, the passage says "I enjoyed the work immensely" - proving he was genuinely interested, not just motivated by money.
Hence, Option 2 -> The narrator's physical reaction (blinking) reveals panic when confronted with a question he couldn't answer. His instant realization about his livelihood shows he was practical and could quickly assess what was at stake, demonstrating adaptability in a high-pressure situation. -> correct
