What does the paragraph say about kelp fibers?

(4) Since these fibers are usually made from natural materials, they take less energy to produce. Kelp, for instance, grows with sunlight. It is one of the fastest-growing living things on Earth. Kelp grows up to two feet in a single day. Humans do not need a factory to create this resource, so it does not pollute the air. Nature does the work for us.

Argumentative texts might ask about the intended audience. Who is the author writing the article for? Who would be interested or who would need convincing?

​Discuss who you think the intended audience would be.

Answer choice C can't be correct because there is no mention of changing the plastic.

To prove answer B, you would say that the author focuses on future research to improve the quality of these fabrics.
