Correct! The official European Union's website does not have a specific term for the withdrawal of a nation from the Union.I enjoy this trivia however it is also the most inaccurate trivia around. An example is Brexit which relates only to Britain leaving the EU and does not apply to any state leaving.
According to Google….
Natalie Portman 9th June 1981
Scarlett Johansson 22nd November 1984
Jennifer Lawrence 15th August 1990
Emma Stone 6th November 1988
So the answers given for #7 do not reflect to the question asked!!!
