Question

which statement best expresses the central idea of the passage? a. rivers create dangerous conditions that make travel difficult in rural areas. b. bridges to prosperity demonstrates how design thinking can address connectivity challenges and reduce rural poverty. c. engineers often respond to global problems after witnessing unsafe conditions. d. funding and donations are essential to completing construction projects.

Explanation:

To find the central idea, we analyze each option:

• Option A focuses only on rivers' dangerous conditions for travel, which is likely a detail, not the main idea.
• Option B mentions "Bridges to Prosperity" using design thinking to tackle connectivity issues and reduce rural poverty. This sounds like a comprehensive main idea as it involves a project (Bridges to Prosperity) and its purpose (addressing challenges and reducing poverty) with design thinking.
• Option C is about engineers' response to global problems after seeing unsafe conditions, which is more about engineers' reaction rather than a central idea of a passage likely centered on a project like Bridges to Prosperity.
• Option D is about funding for construction projects, which is a detail, not the overarching central idea.

So the best option is B as it captures a project and its broader goals related to rural issues.

Answer:

B. Bridges to Prosperity demonstrates how design thinking can address connectivity challenges and reduce rural poverty.
