问题     The ability to move to find new work has long been a
cornerstone of the American Dream. There is growing concern that
being stuck in place contributes to higher levels of unemployment.
Our analysis, therefore, finds no correlation whatsoever between【M1】______
the percentage of residents who were born in a state and either the
overall rate of unemployment and its change over the past year.【M2】______
There is also no correlation between it and the level of income
inequality. States with higher percentages of home grown up【M3】______
residents do however have higher poverty rates. State mobility
appears to be related to residents’ perceptions of their future
economic conditions. The percentage of residents born in a state is
closely associated with the percentage of people in the state who
see the economy getting worse and negatively associated with the【M4】______
percentage who perceive the economy to be getting better. This
likely reflects a difference in the levels of income and skills what【M5】______
underlie these divergent perceptions about the economy.
    State-level mobility is also associated with key dimensions of
health and well-being. Low mobility states have higher levels of
obesity and smoking and higher levels of happiness and【M6】______
well-being. The percentage of residents born in a state is positively
correlated with smoking and obesity, as well as deaths from【M7】______
cardiovascular disease, heart disease, and cancer. Converse, the【M8】______
level of happiness or subjective well-being is negatively associated
with the percentage of residents born in a state. And many have【M9】______
focused on the economic effects of mobility, our analysis suggests
it play an important role in health and happiness as well.【M10】______
【M9】
选项
答案And一Whereas／While
解析 语篇错误。根据上下文语义判断，句间的逻辑关系应为对比关系，前半句指出很多研究关注的是人口流动性对经济的影响，后半句则说我们的研究表明人口流动性对人们的健康和幸福起着很重要的作用，二者形成对比，故应把And改为While或Whereas。
