I want to know the answer to the following question:
Along with Eisenhower, Macmillan and de Gaulle, what leader attended the Four Powers Paris Summit?
All the background I'm provided with is that "The 1960 Four Power Paris Summit between President Dwight Eisenhower, Nikita Khrushchev, Harold Macmillan and Charles de Gaulle collapsed because of the incident.". Is that enough to answer the question?
Answer: yes
