Interpreting Graph Peaks in Mosquito Activity

Steps:

• Identify the y-axis as number of mosquito bites and x-axis as time of night.
• Locate the highest point on the graph line for average bites.
• Note the time interval corresponding to that peak value.
• Confirm no higher points exist elsewhere on the timeline.

Why C is correct:

• Graphs of periodic data like bites follow visual peak identification, where the maximum value directly indicates the interval of highest activity (01:00–02:00).

Why the others are wrong:

• A: Graph shows bites, not net usage patterns by time.
• B: Data compares overall effects, not greater impact post-midnight.
• D: Option is incomplete and unsupported; nets reduce bites generally, not specified by evening vs. after.

Final answer: C
