Jason was explaining water pollution to his class. He said, "Fertilizers and pesticides in fields can pollute water. However, the fields need to be near a lake or ocean to pollute the water. Drinking water polluted with these chemicals can have serious effects on people's health." What is incorrect about Jason's statement? Fertilizers and pesticides can only pollute salt water, and not drinking water.
Fertilizers and pesticides cannot pollute the Earth's water supplies.
Fertilizers and pesticides can pollute ground water even far away from lakes and oceans.
Polluted drinking water does not have serious effects on people's health.

what is the question here?

- "a nonrestrictive clause functions as a modifier to a noun (that is an object, person or concept). these clauses can be described by the following three options: it is set off by comas, it contains a subject and a verbs and it adds nonessential information to the sentence.

for example, in "here is bill gates, who confounded microsoft software company" we can identify "who confounded microsoft software company" as a nonrestrictive clause modifying the noun bill gates. this clause can be describes as a nonrestrictive clause because it is separated by a comma, it adds nonessential information to identify who bill gates is and it must contain both a subject (who) and a verb (confounded)."
