Question

Ocean Plastics

Answer 1

Answer: C

to inform people about the negative impacts of plastic pollution

Explanation:

There are a few pieces of evidence in the article that show that the author is writing to inform the reader of plastic pollution. For instance,

• "Risks to human health from microplastics in seafood are currently being assessed," tells the reader that microplastics that reach the ocean could be potentially be a negative impact to humans and seafood alike.

• "Every year, hundreds of thousands of sea creatures, both large and small, die from complications relating to plastic debris," informs the reader of the dangers of plastics to marine life.
• "Birds, turtles, fish, and other marine life ingest the plastic pieces," summarizes the animals that accidentally ingest the plastic, harming them in the process.
• "Since plastic never completely biodegrades, almost every piece of plastic ever produced is still in the environment in some form," claims that plastic never biodegrades and heavily implies the danger of continuing to use plastic and polluting with it.

These four points summarize the author's informative argument about the dangers of plastics.

Answer 2

Answer:

C.  to inform people about the negative impacts of plastic pollution

Explanation:

The author throughout the passage describes the negative impact of plastic and the types of plastic that pollute the environment. It's a descriptive report of the effects of plastic.

Why not A: The author never discusses good types of plastic, so we can rule this answer out.

Why not B: The author never goes so far as to say that it's the most harmful, or even to compare it to other pollutants (as the word "most" implies).

Why not D: The author is very informative. This isn't a persuasive essay appealing to emotions or logic, just a factual (if somewhat one-sided) description of the problem.
