To determine how the author develops the central idea in paragraph 3, you'll need to closely examine the content and focus of that specific paragraph. Let's break down the options based on common themes they address:
A. If paragraph 3 contrasts afforestation (the creation of new forests) with reforestation (the restoration of existing forests), then option A would be correct.
B. If paragraph 3 illustrates the broad impacts of deforestation on a country's ecology, economy, or social well-being, then option B would be accurate.
C. If paragraph 3 outlines specific steps or methods for combating deforestation within natural habitats, option C would apply.
D. If the paragraph provides a specific case study or example of successful reforestation efforts, then D would be the proper choice.
You will need to analyze paragraph 3 against these descriptions to accurately identify which option best represents how the author develops the central idea in that paragraph. If you provide the text of paragraph 3, I can help you determine the best answer.
