　　托福阅读句子简化题：The Origins of Agriculture

　　【Paragraph 3】Climatic changes at the end of the glacial period 13,000 years ago have been proposed to account　　for the emergence of farming. The temperature increased dramatically in a short period of time (years rather than　centuries), allowing for a growth of the hunting-gathering population due to the abundance of resources. There were,　however, fluctuations in the climatic conditions, with the consequences that wet conditions were followed by dry ones, so　that the availability of plants and animals oscillated brusquely.(The Origins of Agriculture)
