Getting to the Answer: Reread paragraph 4 for information that will help you understand how to read the graphic. Use that information to calculate the precise start and end time for the solar flare as indicated in the graphic. The passage states that a solar flare is represented by any Kp-Index of 5 or higher. While there is one three-hour period where the Kp-Index reached 6, there is a consistent period where the chart shows readings of level 5 or higher. Choice (D) is the correct answer. This choice gives the complete time period showing a reading of level 5 or higher, according to the chart.
