Question

read the passage.

one way that campers can show their concern for the environment is by caring for the waterways around their campsites. at cleanup time, soaps and disinfectants with natural ingredients should be used since those with chemicals can harm water ecosystems. after campware is washed, dishwater should be emptied two hundred feet or more from streams or rivers. natural filters like ground soil help to clean runoff before it enters waterways.

some environmental experts claim that all forms of camping cause harmful water pollution. but when campers are thoughtful about their water use and cleaning processes, they can enjoy visiting delicate ecosystems without harming the plants and animals that are sensitive to changes in water quality.

which statement best summarizes the author’s point of view about camping?

the author agrees with environmental experts that campers can protect waterways but thinks that it is best to avoid camping altogether.

the author agrees with environmental experts that camping is a valuable activity but questions whether it can be done responsibly.

the author agrees with environmental experts about the harms caused by soaps and disinfectants but disagrees about the best alternative products.

the author agrees with environmental experts that water pollution is a concern but disagrees that camping always causes harmful pollution.

Explanation:

1. Analyze the first option: The passage says campers can enjoy camping without harming ecosystems, so the author doesn't think camping should be avoided. Eliminate this.
2. Analyze the second option: The author shows that camping can be done responsibly (e.g., using natural soaps, proper dishwater disposal), so they don't question if it can be done responsibly. Eliminate this.
3. Analyze the third option: The passage doesn't discuss a disagreement about alternative products. The author just recommends natural ingredients, not a disagreement on alternatives. Eliminate this.
4. Analyze the fourth option: Environmental experts say all camping causes harmful pollution, but the author says when campers are thoughtful, they can camp without harm. So the author agrees pollution is a concern but disagrees that camping always causes harm. This matches.

Answer:

The author agrees with environmental experts that water pollution is a concern but disagrees that camping always causes harmful pollution.
