那儿有多少只奶牛?
How many farms are there that house 10, 000 cows, the a large herd is only 200.
问题是能有多少农场可以容纳10000头奶牛?通常一个大的牧群也就200头。
Okay. Then you can look at how many things like cows are raised in the United States, and how many acres there are of carrots, or wheat, or corn, or whatever it is.
好了,然后就可以看看,比如,美国养了多少头牛,种植了多少英亩的胡萝卜,小麦,玉米,或其他东西
