Question

how do the details in paragraph 9 support the key idea that tourism to antarctica should be more carefully managed?
a by highlighting the need for essential care of people who visit or work there
b by summarizing the treaties that have addressed the issue
c by describing what has been happening to animal life on the continent
d by explaining the likely negative effects to the continent and ocean

Explanation:

To determine how paragraph 9 details support the key idea about managing Antarctic tourism, we analyze each option:

• Option A focuses on people's care, but the key idea is about tourism management for the region, not just people. Eliminate A.
• Option B mentions summarizing treaties, but the question is about details in the paragraph supporting the idea, not treaty summaries. Eliminate B.
• Option C focuses on animal life, but the key idea is about overall tourism management (not just animal - related). Eliminate C.
• Option D: Explaining negative effects on the continent and ocean shows why tourism needs careful management (to avoid those negative effects), which directly supports the key idea.

Answer:

D. By explaining the likely negative effects to the continent and ocean
