Answer 1

From June to December, the rainfall data points are as follows:

• June: 0.2 inches
• July: 0.45 inches
• August: 0.55 inches
• September: 0.7 inches
• October: 1.6 inches
• November: 2.4 inches
• December: 3.2 inches

Analyzing these values, we see that the average rainfall starts to increase from June (0.2 inches) to July (0.45 inches), and continues to rise through August (0.55 inches), September (0.7 inches), October (1.6 inches), November (2.4 inches), and December (3.2 inches).

Therefore, during the months from June to December, the average rainfall consistently increases.

The correct response is: the average rainfall increases.
