Question

in 2017, nzambi matee, a young woman from kenya, wanted to use her education in physics and materials engineering to promote environmental sustainability. she saw the possibility of utilizing kenyas extensive amount of discarded plastic as a resource. with time and persistence, matee built a machine to make bricks the size and shape of paving stones. in her efficient manufacturing process, bottles, bags, and other discarded plastic items are combined with sand, then melted and shaped. matees bricks are lighter but more durable and less expensive than concrete. they can be used for an array of building projects, including constructing walls, pathways, and structures. matees work gained international attention in 2020 when a united nations program honored her as a \young champion of the earth.\ this award acknowledges an advocates actions toward a greener planet. which is the best summary of the passage? as an engineer seeking to protect natural resources, kenyan nzambi matee designed a machine that helps in the disposal of plastic. by removing plastic trash from the environment, natural resources can be preserved. the bricks that kenyan nzambi matee makes are less expensive to produce than traditional construction materials. made of melted plastic and sand, they can be used for a variety of purposes. while the work of kenyan nzambi matee was an important step forward in addressing kenyas waste problem, the machine process she designed can

Explanation:

The passage mainly tells about Nzambi Matee, a Kenyan using her engineering - related knowledge to make bricks from discarded plastic for environmental sustainability and getting an international award. The second option focuses on the characteristics of the bricks she makes, which is a part of the story. The first option is too general about protecting natural resources and not specific enough about the brick - making. The best summary should cover her innovation of making bricks from plastic, their advantages, and her recognition. So the second option better summarizes the key aspects of the passage.

Answer:

The bricks that Kenyan Nzambi Matee makes are less expensive to produce than traditional construction materials. Made of melted plastic and sand, they can be used for a variety of purposes.
