Answer to Question 1
Ans: A
Individuals who make up the U.S. homeless population are among the most marginalized and vulnerable to disabilities and disease.
Answer to Question 2
Ans: D
The National Center for Health Statistics (NCHS) reports that 34.4 million (11.8) of noninstitutionalize d individuals have a limitation in usual activities due to a chronic condition. The Centers for Disease Control and Prevention maintains information on diseases, not limitations of individuals. The U.S. Census Bureau has more specific disability information, not the general information. The World Health Organization does not have this type of disability information but is more involved in control and prevention on a more global basis.
