I'm going to read you a short statement about hypoxia. I want you to listen carefully, and then I'll ask you some questions. This is not a test. Hypoxia is an extremely toxic condition for animal life and means that not enough oxygen is available to allow them to live. This may occur in lakes, river, streams, seas, gulfs, oceans, and estuaries when oxygen is used by decaying plants and other material.
Hypoxia is a condition that is present in the Gulf of Mexico off the coast of Louisiana.
For each, tell me whether you think this is an effective solution or not an effective solution.
