6. Which of the four sentences is not neutral?

My answer is #3. Is that right?

I agree.

Yes, you are correct. Sentence 3 ("Netta and Jim were sharply split over the issue of free trade") is not a neutral statement. This sentence implies that there was a strong division between Netta and Jim on the issue of free trade. The word choice "sharply split" suggests a significant disagreement, which indicates a bias towards a specific viewpoint. In contrast, the other sentences (1, 2, and 4) simply state the existence of a difference in opinions without introducing any judgment or partiality.
