# Brief Explanations:
- **Option A**: The horizontal axis (likely representing time, e.g., days) has a scale from 0 - 50, but the graph’s data seems to be within 0 - 25 or so, and the scale might not match the data’s context (e.g., if it’s days, the scale could be inappropriate as the data doesn’t use the full range, but more critically, the horizontal axis lacks a label (e.g., “Day” or “Time”), so the scale’s appropriateness is less clear than the labeling issue. Wait, no—actually, the horizontal axis ticks: looking at the graph, the horizontal axis has ticks at 0,10,20,30,40,50, but the data’s x - values (time) for the temperature graph—if it’s, say, days, but the graph’s curve is within 0 - 20 or so, but the main issue is **axis labeling**: the horizontal axis has no label (what does 0 - 50 represent? Days? Hours? Months?). So **E** is true. Also, let's analyze each option:
    - **A**: The horizontal axis scale (0 - 50) – if the data is about temperature over time (e.g., days), the scale itself (range) isn’t necessarily inappropriate unless we know the context, but the bigger issue is labeling. However, let's check the ticks. Wait, the horizontal axis ticks: the graph’s curve is plotted, but the horizontal axis (x - axis) – what is it? The problem is the axis labeling is incomplete (E): vertical axis is “Temperature (Fahrenheit)”, horizontal axis has no label (e.g., “Day of the month”, “Time (hours)”), so E is true.
    - **B**: Horizontal axis ticks: 0,10,20,30,40,50 – are they placed correctly? The spacing between 0 - 10, 10 - 20, etc., is equal, so ticks are placed correctly. So B is false.
    - **C**: Vertical axis scale (50 - 70, with 5 - degree intervals) – temperature in Fahrenheit, 50 - 70 is a reasonable range for a city’s average temperature, so scale is appropriate. C is false.
    - **D**: Vertical axis ticks: 50,55,60,65,70 – spaced at 5 - degree intervals, which is appropriate for temperature, so ticks are placed correctly. D is false.
    - **E**: Axis labeling: vertical axis is labeled “Temperature (Fahrenheit)”, but horizontal axis has no label (what does the x - axis represent? Time, days, etc.?). So labeling is incomplete. E is true.
    - **F**: Vertical axis (temperature) – a zero - break is used when the axis doesn’t start at 0 but we want to mislead, but here the vertical axis starts at 50, which is a reasonable minimum for city temperature (no need for a zero - break as 0°F is extremely cold and not relevant here). So F is false.
    - **G**: The graph has incomplete axis labeling (horizontal axis unlabeled), so it’s not designed appropriately. G is false.

Wait, also, let's re - check the horizontal axis scale. If the horizontal axis is, say, days, but the data is within 0 - 20 days, the scale (0 - 50) is too wide, but the main issue is labeling. However, the key points:

- **E**: Axis labeling is incomplete (horizontal axis has no label).
- Also, is there another? Wait, the original graph: the horizontal axis – what is it? The problem says “average temperature in a city” – so x - axis should be time (e.g., day, month, hour), but it’s unlabeled. So E is true.

Wait, maybe I missed A? Let's see: the horizontal axis scale – if the data is over a period (e.g., 20 days), and the scale is 0 - 50, the scale is not appropriate because it’s too wide and doesn’t match the data’s range. But the main issue is labeling. However, let's check the options again:

- **A**: “The horizontal axis scale is not appropriate.” – If the x - axis is time (e.g., days), and the data is within 0 - 20, a scale of 0 - 50 is too broad, so scale is inappropriate. But is that the case? Or is the x - axis something else? The graph’s x - axis has ticks at 0,10,20,30,40,50, and the curve is from ~0 to ~25 on the x - axis. So the scale (0 - 50) is wider than the data’s x - range, making the scale inappropriate (A). Also, E: axis labeling is incomplete (no label on x - axis).

Wait, let's re - evaluate:

- **A**: Horizontal axis scale (0 - 50) – if the data is within 0 - 25, the scale is not appropriate (too much empty space, not matching the data’s range). So A is true.
- **E**: Axis labeling – x - axis has no label (what is the x - variable? Time, days, etc.?), so labeling is incomplete. E is true.

Wait, maybe the correct answers are A and E? Let's check each option again:

- **A**: Horizontal axis scale: The x - axis has a scale from 0 to 50, but the data (the temperature curve) is concentrated in the 0 - 25 range (approx.). A scale that is too wide (0 - 50) when the data is in a smaller range is inappropriate. So A is true.
- **B**: Horizontal axis ticks: The ticks are at 0,10,20,30,40,50, with equal spacing. So ticks are placed correctly. B is false.
- **C**: Vertical axis scale: Temperature from 50 - 70°F is reasonable for a city’s average temperature, so scale is appropriate. C is false.
- **D**: Vertical axis ticks: Ticks at 50,55,60,65,70, spaced 5°F apart, which is appropriate. D is false.
- **E**: Axis labeling: Vertical axis is labeled “Temperature (Fahrenheit)”, but horizontal axis has no label (e.g., “Day”, “Time”). So labeling is incomplete. E is true.
- **F**: Vertical axis zero - break: The vertical axis starts at 50, which is a reasonable minimum for city temperature (no need for a zero - break as 0°F is not relevant here). F is false.
- **G**: The graph has an inappropriate horizontal scale (A) and incomplete labeling (E), so it’s not designed appropriately. G is false.

So the true statements are A and E.
