Correct Option:
Assumption 1 is valid. The passage explicitly states that food is lost or wasted "throughout the supply chain, from initial agricultural production to final household consumption." The distribution mechanism constitutes a critical component of this supply chain. Therefore, reimagining and enhancing the effectiveness of the food distribution mechanism is a logical and necessary step to mitigate the reported loss and wastage of food.
Incorrect Options:
Assumption 2 is not supported by the passage. While the passage details the significant environmental and sustainability impacts of food wastage, such as land degradation and 3.5 billion tonnes of carbon dioxide (CO₂) production, it does not assert that reducing food wastage is a "social and moral responsibility of all citizens." This statement introduces a value-based judgment that cannot be directly inferred or assumed from the factual information presented in the passage. The passage focuses on the scale and consequences of the problem, not on assigning specific moral obligations to individuals.
Therefore:
- Option 2 is incorrect because Assumption 2 is not valid.
- Option 3 is incorrect because Assumption 2 is not valid.
- Option 4 is incorrect because Assumption 1 is valid.
