Which president served from 1977 to 1981 and created the Department of Energy and the Department of Education, while facing events such as the Iran hostage crisis and the Soviet invasion of Afghanistan?

• A. Ronald Reagan
• B. Richard Nixon
• C. Gerald Ford
• D. Jimmy Carter

Answer: (D)

Identifying the president who served during these years and oversaw major changes in the federal government. Jimmy Carter, who was in office from 1977 to 1981, launched a significant reorganization of federal agencies by creating two new departments: the Department of Energy in 1977 to handle energy policy and research in response to the energy crisis, and the Department of Education in 1979 to coordinate and support federal education programs. His tenure also included major international challenges that defined his presidency, notably the Iran hostage crisis beginning in 1979 and the Soviet invasion of Afghanistan in 1979, both shaping Cold War tensions and U.S. foreign policy decisions. Among the options, only Carter fits the exact timeframe and the specific departmental creations described.
