For this chain-of-thought reasoning and answer, what was the question?
The hunting season last 12 / 4 = 3 months. So he goes hunting 3 * 6 = 18 times a year. That means he gets 18 * 2 = 36 deers per year. So he catches 36 * 600 = 21,600 pounds of deer a year. That means he keeps 21600 / 2 = 10,800 pounds of deer a year.
 A: 10800
Q: Jack goes hunting 6 times a month. The hunting season lasts for 1 quarter of the year. He catches 2 deers each time he goes hunting and they weigh 600 pounds each. He keeps half the weight of deer a year. How much deer does he keep in pounds?
