Final answer:
Arab immigrants have more social capital in Michigan than in other states, which could explain why Arab IMGs in Michigan are more likely to pass their licensing exams.
Step-by-step explanation:
The best explanation for why Arab IMGs in Michigan are more likely to pass their licensing exams than in any other state is that Arab immigrants have more social capital in Michigan than in other states. Social capital refers to the network of relationships and connections an individual or group has that provides resources and support. In Michigan, there is a high concentration of Arab immigrants, particularly in cities like Detroit, which creates a strong community and support system for Arab IMGs.
