Answer 1

First of all, what is "precise?"

"Precise" means that you want to find a sentence that has more details, but not paraphrasing.

Here we have four sentences.

But if you look, only sentence A has more details about the traffic light system.

Answer 2

A: I believe small changes to the timing would improve this traffic light system.

Step-by-step explanation:

The revision in the option A makes the sentence more precise because it is objective and clear. Someone saying that he or she has 'many beliefs' is only a vague statement if they want to call attention of the responsible for the traffic light system. Therefore, a more specific and objective suggestion can obtain better response.
