The first question relates to today, November 8th. The remainder are not date specific but follow a loose theme.

One
On this day in 1960, John F. Kennedy was elected President of the United States, as a result of defeating whom in the presidential election?
Two
John F. Kennedy’s term ended tragically when he was assassinated in Dallas. This makes him one of four US presidents killed while in office. Who is the only British prime minister to have been assassinated?
Three
President Kennedy’s 1,037 days in office are certainly not the shortest. Which US president served the shortest term? Secondly, how long (or short) was the shortest term: 31 days, 51 days or 71 days?
Four
Liz Truss’s 49 days in 2022 is by far the shortest term of any UK prime minister. Which prime minister from the first third of the 19th century served this shortest term? Secondly, how long was this second shortest premiership: 99 days, 119 days or 139 days?
Five
Albino Luciani served in which office for 33 days in the second half of the 20th century?
Good luck! I’ll post the answers later.
