We can infer from paragraph 4 that_________.A、a high unemployment rate may lead to violence
B、world recession may sometimes result in youth quake
C、the unemployment rate in Europe and the US is not high
D、unemployment may cause young people to emigrate to other countries
【正确答案】：A
【题目解析】：判断推理题。题干要求根据第四段的内容进行推断。原文第四段讲述年轻人失业的后果，提到了中东的无业青年愤怒地走上街头，西班牙、意大利、葡萄牙等年轻人失业率高的国家violent crimes（暴力犯罪）数量上升。因此可以推断出失业可能导致暴力。故而A为正确答案。
