The Correct Option is B

Solution and Explanation


Step 1: Understanding the Concept:

Finding the central idea requires capturing the broad theme that unifies every sentence in the passage rather than focusing on a single detail or an over-generalized claim.

Step 2: Key Formula or Approach:

Analyze the logical development of the short text:
• Sentence 1 establishes the main topic: "pressing challenges."
• Sentence 2 provides details on risks: "severe environmental consequences."
• Sentence 3 outlines the ongoing response: "governments attempting solutions."

Step 3: Detailed Explanation:

Option (a) is completely false because the text notes that implementation "remains uneven." Option (b) accurately sums up the primary points: it points out the problems (challenges) and acknowledges the ongoing effort to fix them (action). Option (c) is explicitly contradicted by the text, which lists biodiversity loss as a consequence of climate change. Option (d) is incorrect because the passage says "scientists warn" collectively, showing agreement rather than conflict.

Step 4: Final Answer:

The central idea of the passage is that climate change poses serious global challenges requiring action.
