Explanation:

Part A

To determine how the author supports the idea that Navajo men who volunteered to fight in WWII had isolated lives, we analyze each option:

• Option A: Stating messages were impossible to understand relates to the code, not isolation. Eliminate.
• Option B: "Most had never been off their reservation" directly shows limited exposure to the outside, supporting isolation. This is correct.
• Option C: Oral communication doesn't indicate isolation. Eliminate.
• Option D: Naming planes/boats after animals is about the code's terminology, not isolation. Eliminate.

We need to find the paragraph that supports the answer to Part A (about isolation from never being off the reservation). Typically, a paragraph discussing their limited exposure (like living on the reservation and not traveling) would support this. Assuming paragraph 3 (or the relevant one) contains this context, but based on common text structures, if Part A's answer is about never being off the reservation, the paragraph that introduces their background on the reservation (e.g., paragraph 3) would support it.

The word "skeptical" means having doubt or being doubtful. In the given paragraph, "Marine officers were skeptical at first" shows their doubt about the Navajo code proposal, matching the meaning of "doubtful".

Answer:

B. by stating that most had never been off their reservation

Part B
