Using a map key to answer questions about Peter's neighborhood.

Let me carefully analyze the map to answer each question.

Question 1: Which road has the most houses where Peter lives?

Looking at the map, I need to count the red house icons along each road:
- Pinto Road: I can see houses in the upper left area near "Pinto Road" label - there appear to be about 4 houses clustered there.
- Hope Road: This road runs through the middle and bottom of the map. I can see houses along Hope Road - there's one near the center (above Forest Park), and two on the right side labeled "Hope Road". That's about 3 houses.
- Smart Road: Near the top right, by the school. I don't see clear houses directly on Smart Road.

Wait, let me recount more carefully:
- Upper left cluster near Pinto Road: I see approximately 4 red house icons
- Center area above Forest Park on Hope Road: 1 house
- Right side on Hope Road: 2 houses

So Pinto Road appears to have the most houses (about 4).

Actually, looking again at the map description - the houses in the upper left are near "Pinto Road" label. There seem to be 4 houses there. On Hope Road, there's 1 in the middle and 2 on the right = 3 houses.

Answer to Q1: Pinto Road

Question 2: Which building is closest to Peter's home?

Peter's home is the black house icon. Looking at what's near it:
- There's a church (with steeple) very close to Peter's home, just to the left/below it.
- The school is further away on the right side.

The church appears to be the closest building to Peter's home.

Answer to Q2: Church

Question 3: What is the name of the longest road where Peter lives?

Looking at the roads:
- Hope Road: This road appears to run from the bottom left, through the middle, and to the bottom right - it seems to be the longest road on the map, spanning across most of it.
- Pinto Road: A shorter road in the upper left area.
- Smart Road: A short road at the top right.

Hope Road clearly appears to be the longest road as it stretches across the entire map from left to right.

Answer to Q3: Hope Road

Final Answer:
1. Pinto Road
2. Church
3. Hope Road
