Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

[Q]: The motion of an object can be represented by a position-time graph like Graph 1 in the Figure 1.1. In this type of graph, the y-axis represents position relative to the starting point, and the x-axis represents time. A position-time graph shows how far an object has traveled from its starting position at any given time since it started moving. Q: In the Figure 1.1, what distance has the object traveled from the starting point by the time 5 seconds have elapsed? A: The object has traveled a distance of 50 meters. In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure 1.2, then the slope is zero and so is the velocity. The position of the object is not changing. The steeper the line is, the greater the slope of the line is and the faster the objects motion is changing. Its easy to calculate the average velocity of a moving object from a position-time graph. Average velocity equals the change in position (represented by d) divided by the corresponding change in time (represented by t): velocity = d t For example, in Graph 2 in the Figure 1.2, the average velocity between 0 seconds and 5 seconds is: d t 25 m 0 m = 5 s0 s 25 m = 5s = 5 m/s velocity =
[A]: the slope of a position-time graph can be used to find the moving objects

[Q]: There is always a man who stands on different comers of the street in our city, holding a sign that reads "Will work for food for my family". Normally I don't have much money to help him. When my mother is with me and she sometimes makes me pull over and then she will hand him some money. Tonight, I was on my way to the store to get some milk when I saw the man. My daughter and her friend were in the car. We all felt awful that this man was standing out in the cold, wet weather. Many people had made comments that he should be able to work. I often wondered why he would stand out there rather than be in the warmth of a building, working. Well, he might not have an address, and he may need an address in order to apply for a job. Either way, I don't feel it is _ to judge. As I was sharing that feeling with my daughter and her friend, I decided that I needed to help this man. I wanted to show the girls the importance of helping others, not about worrying whether he was legitimately struggling or not. So, when we pulled over to give him some money, I said, "God bless you," and he said it back to us. But the girls and I were still concerned that he would be cold, standing out in the bad weather. So we got him a hot chocolate and a hamburger. My daughter handed them to him and l told the man that the girl wanted to help him because she was worried about him being cold. He was very sweet and appreciative. We all left with smiles, especially me, because, as we were pulling away, the girls were talking about ways they could raise money to help the man and others like him. It was the best trip I have ever made to get milk!!!
[A]:
Why did the author decide to help the man?
