I'm unable to view the passage directly, but I can help you with techniques on how to answer comprehension questions.

1. **Identify Key Ideas**: Look for main themes and important details in each paragraph.
2. **Understand Vocabulary**: Pay attention to the context in which specific words are used, especially nuanced terms like "deteriorate" or "sustain."
3. **Summarize**: Create brief summaries of paragraphs as you read.
4. **Refer Back**: Use the passage to find evidence for your answers; refer back to it often.
5. **Eliminate Wrong Answers**: Often, you can find the correct answer by ruling out ones that are clearly incorrect.

If you have specific questions about the text or its content, feel free to ask!
