Final answer:
Option 1 best explains FreshPaper's public effect by extending food freshness, reducing waste, and providing regular access to essential nutrients, highlighting the importance of inventions that serve public needs.
Step-by-step explanation:
The choice that best explains how FreshPaper affects the public is Option 1: Kavita's invention helps many people keep food fresh longer. This innovation has a significant impact on public well-being by prolonging the lifespan of food, thus reducing waste and enhancing food security. Food preparation inventions, like FreshPaper, are crucial because they provide continuous access to essential vitamins, minerals, fats, and carbohydrates, especially when natural food sources are scarce or out of season. Additionally, they support the global transportation of food, aiding in dietary variety.
While Kavita's business operations (Option 2), international reach (Option 3), and patent (Option 4) may be relevant to her venture's success, they do not directly explain the invention's effect on the general public. Indeed, patents encourage innovation by allowing inventors to profit from their creations and thus incentivize further research and development. However, the ultimate benefit to the public comes from the invention's application—keeping food fresh longer—underscoring the importance of not only innovation but also of inventions that serve a public good.
