Answer 1
The text gives Carter more credit than his successor. The problems with the energy crisis and inflation were not of Carter's own making. But like Ford, Carter had a difficult time working with Congress, even though it was controlled by members of his party. Carter's successes in foreign policy, such as the Camp David Accords and Panama Canal Treaty, were undercut by the disaster in Iran. A strong essay might point out that any president would have been hard pressed to come up with solutions to these problems.
Answer 2
The text notes that the 1965 Immigration Act ended the national quota system for immigration and opened access to the United States from areas other than Europe. Increasingly, large numbers arrived from Mexico, Latin America, the Caribbean, and Asia. Within two decades, more than half of all immigrants arrived from Latin America, and nearly a fourth from Asia. Because immigration laws favored professionals with education and skills and the service sector attracted large numbers of workers with low skill levels and education, many immigrants, especially those from Mexico and Latin America, entered the United States illegally. Attempting to stem the tide of this illegal immigration, the Immigration Reform and Control Act was passed in 1986 . Despite providing amnesty and eligibility for citizenship for many illegal aliens, the flow of immigrants entering the country was unaffected and continued to expand due to growing demands in the labor markets for unskilled workers.
