Answer:
The correct answer is that there is evidence about what happened with Emily earlier on.
Explanation:
The people of the city spent their entire lives talking about Emily, and saying "poor Emily," instead of paying attention to what was really happening.
For example, when she went to buy poison from the pharmacy, and the pharmacist asked her what the poison would be for, Emily never said for what she was going to use it. However, the pharmacist sold him arsenic.
Other evidence is the foul smell that came from his home, and the disappearance of Homer Barron. If someone in the city had paid more attention, they could have realized what was actually happening.
