Question

BlackTom AI · Accepted Answer

Aquaculture provides an alternative source of seafood that can relieve pressure on wild fisheries while introducing environmental concerns, so the main idea balances benefits and the need for sustainable practice.

1) Relevant knowledge points and concepts
- Aquaculture (fish farming) can increase food supply and reduce pressure on wild fish stocks, addressing overfishing and food security concerns.
- Aquaculture can cause environmental impacts (pollution, habitat change, disease, feed demands) if not managed sustainably.
- A paragraph’s main idea typically synthesizes the topic (aquaculture) with the author’s central claim (it helps but must be managed sustainably).

2) Step-by-step reasoning
- Identify the topic: the paragraph discusses aquaculture/fish farming.
- Identify the claims: it presents positive roles (addressing overfishing and food security) and also emphasizes environmental risks or conditions.
- Combine topic and central claim: the most comprehensive summary will state both the potential benefits and the requirement for sustainable practice to mitigate environmental impacts.

3) Calculations/Intermediate steps
- Not applicable (no numerical calculations required).

4) Why the correct answer is correct
- Option (a) explicitly states both sides: aquaculture can help with overfishing and food security (the benefit) and must be done sustainably to reduce environmental impact (the caveat). This captures the balanced thesis that the paragraph conveys: supportive of aquaculture’s role but conditional on sustainability.

5) Why the other options are incorrect
- (b) Claims fish farming is the most cost-effective way to produce high-quality seafood for vulnerable communities — too specific and value-laden; it omits environmental caveats and frames a narrower economic claim.
- (c) Focuses only on causes of wild fish stock decline (environmental degradation and overfishing) and does not summarize aquaculture’s role or sustainability concerns.
- (d) Emphasizes controversy due to antibiotics/chemicals — too narrow and negative, ignoring the paragraph’s mention of benefits and broader sustainability requirement.

6) Conclusion
- Therefore, option (a) best summarizes the paragraph’s main idea. This confirms the provided correct answer: a.
