What is the main purpose of the authors in writing this text?

Question

BlackTom AI · Accepted Answer

The authors focus on the private sector’s contributions to sustainability, arguing that businesses have roles, responsibilities, and levers to help achieve sustainable development.

1) Relevant knowledge points and concepts
- Main idea identification: an author’s primary purpose is found in the topic emphasized and the actions or audience targeted. 
- Key concepts here are: “sustainable development,” “role of businesses,” “private sector engagement,” versus alternative emphases such as “population growth” or “government progress on SDGs.”

2) Step-by-step reasoning
- Step 1: Look for repeated subject and verbs. If the text repeatedly mentions companies, corporate practices, investment, partnerships with business, or private-sector solutions, that signals a business-focused purpose.
- Step 2: Identify the audience and call to action. If recommendations are directed at firms or investors (e.g., adopt sustainable practices, measure impact), the authors aim to discuss business roles.
- Step 3: Contrast with other options: if the text does not center on demographic pressure or resource limits, it’s not about population growth; if it does not primarily evaluate government progress or SDG statistics, it’s not option B.

3) Calculations / intermediate steps
- No numerical calculations apply; the “intermediate steps” are the textual checks above (topic repetition, targeted audience, recommended actions).

4) Why the correct answer is correct
- The correct answer (C) matches a text that highlights business responsibilities, examples of corporate initiatives, and how firms can advance sustainability. This focus on private-sector mechanisms and recommendations directly supports the claim that the authors’ main purpose is to discuss the role of businesses in achieving sustainable development.

5) Why the other options are incorrect
- A is incorrect because analysing population growth would emphasize demographics, resource depletion, birth rates, or carrying capacity—topics not central if the text targets businesses.
- B is incorrect because examining government progress on SDGs would center on policy performance, national statistics, and governmental accountability rather than corporate action.

6) Conclusion
This reasoning confirms the correct answer: C. Discussing the role of businesses in achieving sustainable development.
