单选题
Farming emerged as a survival strategy because man had been obliged ______.
A、
to give up his former way of life
B、
to leave the coastal areas
C、
to follow the ever-shifting vegetation
D、
to abandon his original settlement
【正确答案】
A
【答案解析】
[解析] 该题考查第一段最后两句的逻辑关系。第四句中的old way of life指人类最初以狩猎为生，后因气候变暖及猎物濒临灭绝，人类才不得不转而以耕作为生。由此可见农业的出现是人类放弃传统生活方式的结果。B、C、D三项的描述与本题无关。
