Answers 

1. b

2. a

3. d

4. d but roasting chestnuts and grilling steaks at least smell awfully good.

5. a

6. c, and then, later, a North Pole, or Arctic, hole appeared.

7. c, fluorosis being a darkening of your teeth from excess fluorides.

8. c, at least that's the hope.

9. d, though it is good to wear sunscreen for protection against the sun's UV rays because of the damaged ozone shield.

10. c, you should also watch for air quality alerts, but these apply to ground-level ozone.
