Answer: e. Exposed US for spying on the USSR & lying about it at the highest levels of our government
Explanation:
The U-2 Spy Plane Incident happened in May 1960 when the Soviet Union captured American pilot Francis Gary Powers after shooting down his U-2 spy plane which was being used by the US to gather information about the Soviet Union's nuclear programme.
The Soviets did not initially say that they had captured the pilot so the US lied about the incident and said it was a weather plane that had flown off-course. The Soviets then revealed that they had Powers in custody at which point the US relented and took responsibility.
