6. Parent: “Students these days do not study nearly as hard as they did when I was young. When I was 15, I spent five hours a day just completing my homework. Now all the kids can finish it in three hours or less. This generation is lazier than my generation.”
Student: “It’s true that we spend less time on homework. But we study more subjects in school and are actually required to learn more. We’re not lazy, but we spend less time on homework because we have more technology, like graphing calculators and the Internet to make our work faster.”
In responding to the parent, the student does which of the following?
7. Two scientists designed a study to investigate the impact of a recent sewage spill in a local river. They compared species diversity in the affected river to species diversity in a nearby river not affected by the spill, and found that the species diversity in the two rivers was roughly the same. The researchers concluded that the sewage spill had little to no effect on the health of the affected river.
Each of the following, if true, would undermine the researchers’ conclusion EXCEPT:
8. Nutritionist: “The vitamin content in organic foods and non-organic foods is the same. Therefore, it is a waste of money to pay for organic food products. Organic products are usually more expensive, and so a consumer will pay more for the same nutritional content.”

9. Museum Director: “The City Council’s vote to close the Natural History Museum on January 1st was foolish and will harm the city.

Which of the following is the main point of the Museum Director's argument?
