Question

what solution is proposed for the issue of food shortages and contamination?
○ increased farming
○ research on sources of contamination
○ genetically engineered foods
○ more efficient trading
done ✔

Explanation:

Genetically - engineered foods can potentially address food shortages by increasing crop yields (through traits like pest resistance, drought tolerance). They can also be designed to be more resistant to contamination - related issues (e.g., by engineering plants to be less susceptible to fungal or bacterial infections that cause contamination). Increased farming may not directly address contamination. Research on sources of contamination is more of a diagnostic step rather than a comprehensive solution for both shortages and contamination. More efficient trading helps with distribution but not with the core issues of production (shortages) and contamination prevention at the production level.

Answer:

genetically engineered foods
