Read the following passage about nanotechnology and mark the letter A, B, C or D to indicate the best answer to each of the following questions from 13 to 22.

The zero-waste lifestyle, which promotes eliminating all personal waste, has become a symbol of environmental responsibility in recent years. From reusable containers to bulk shopping and composting,  the movement encourages individuals to radically change their consumption habits. While the intention behind it is commendable, the practicality of achieving a truly zero-waste lifestyle remains questionable for most people.

Waste is part and parcel of today's consumer society. Supermarkets package goods in layers of plastic; online shopping generates cardboard, tape, and protective fillers; even medical care often involves single-use items for hygiene. Expecting individuals to entirely avoid these realities requires a level of privilege, time, and access that many do not have. For example, not every city offers bulk stores or composting services, and not everyone can afford the often higher costs of sustainable products.

Moreover, the pressure to be “zero-waste” can lead to guilt rather than change. When a person who tries their best still ends up discarding a food wrapper or a broken appliance, they may feel that their efforts are meaningless. This absolute mindset can be counterproductive, discouraging broader participation in sustainable practices.

[I] Rather than total elimination, choosing to reuse whenever possible, refusing unnecessary packaging, and supporting circular economy initiatives can collectively shift demand away from disposability. [II] Even small, consistent efforts across a population can significantly reduce environmental harm. [III] Rather than viewing zero-waste as an endpoint, it may be more useful to treat it as an aspiration, a guiding principle rather than a strict rule. [IV] Progress lies not in perfection, but in the widespread willingness to reduce where we can and when we can.

Question 13. Which of the following can be inferred from the passage?

        A. Partial efforts to reduce waste are more achievable than total waste elimination.

        B. Achieving zero waste is a realistic and necessary goal for everyone, regardless of income.

        C. Waste reduction requires individuals to sacrifice convenience without gaining any benefits.

        D. People who fail to live a completely zero-waste lifestyle stop protecting the environment.
