To accurately determine how paragraphs 17 and 18 of the lecture develop the central idea, you should consider the theme or main argument presented in those paragraphs. Without the actual text from the paragraphs, I can suggest a general approach to answering similar questions:
-
Identify the Central Idea: Understand what the central idea of the lecture is. Is it about the importance of conservation, the uniqueness of Kenyan ecosystems, or something else?
-
Examine Key Points in the Paragraphs: Look for specific details in paragraphs 17 and 18 that directly relate to the central idea.
-
Match Responses to Content: Determine which response most accurately reflects the content of those paragraphs as it relates to the central idea.
If I had to make an educated guess based solely on common themes in discussions about Kenya's ecosystems and wilderness areas, I might lean toward:
- by suggesting new ways to save wilderness areas in Kenya
This option typically aligns with the drive to inspire action and solutions, which is often a focal point in discussions about environmental preservation. If the paragraphs indeed discuss strategies or initiatives for conservation, this would effectively strengthen the central idea regarding the importance of protecting Kenya's natural heritage. However, please check the specific content of those paragraphs for a definitive connection.
