Lesson 9 of 14

About this lesson

When someone makes a claim that something "affects us too," the supporting statement must show a direct path from the cause to people being harmed. This question is about ocean plastic pollution — and the correct answer is the one that completes the chain from "plastic in the ocean" all the way to "plastic reaching humans." It's a classic food-chain logic question dressed up as an environmental argument.
