If a graph has no title, which part is missing?

• A. Labels
• B. Title
• C. Axis lines
• D. Scale

Answer: (B)

Graphs communicate data best when they have a clear title that states what is being shown. The title sets the scene, telling you the subject and often the time frame or condition of the data. Without a title, the graph loses immediate context, making it harder to understand at a glance. You can still read axis labels to identify what each axis represents and their units, but the title ties everything together and clarifies the overall message. The axis lines provide the reference frame, and the scale shows the range and spacing of values. So, when a graph has no title, the missing piece is the title itself.
