Question 1(Multiple Choice Worth 3 points) (LC) Which sentence is correct? The scientist said there is only one thing to be done: to save our river "Stop polluting the groundwater with fertilizers." The scientist said there is only one thing to be done to save our river: "Stop polluting the groundwater with fertilizers." The scientist said: there is only one thing to be done to save our river "Stop polluting the groundwater with fertilizers." The scientist said there is only one thing: to be done to save our river, "Stop polluting the groundwater with fertilizers."

The second sentence:

The scientist said there is only one thing to be done to save our river: "Stop polluting the groundwater with fertilizers."

Explanation:

The other sentences do not make good use of the colons.

Colons are used between two independent clauses, e.g.

(He got what he worked for: he really earned that promotion.)

They are also used before a full sentence statement, like in this Question.

The other three sentences do not put the colons in the right places. Only the second one does so.
