Essay

Refer to the figures.

- You are one of a team of scientists studying a newly-discovered planet. You are receiving data from a probe that was landed on the planet by an unmanned mission. Your team is working with the little data you have from the probe to learn as much as you can about the planet's basic characteristics. The figure illustrates data collected by the probe at the same location on the planet during what you suspect are two different seasons (season A and season B). Based on your sketch of the planet at four different positions during its orbit around its sun (the second figure) and the data sent back by the probe, how many growing seasons would the planet have during one complete orbit of its sun?
