Which searches trigger a direct fact in Google's new Q&A feature?

Q: Who is prime minister?

This returns a Wikipedia definition which would be more suited to the question "What is a prime minister?"

Maybe I was being a bit vague in my questioning...

Q: Who is Prime Minister of England?

Returns "England Prime Minister: Tony Blair" and gives a link to more sources:

http://www.google.co.uk/search?q=Who+is+Prime+Minister+of+England%3F&fsrc=1&oi=moresources

I tried locations, with some success:

http://www.google.com/search?q=where+is+the+eiffel+tower
Eiffel Tower Restaurant
Location: Inside the Mandalay Bay

http://www.google.com/search?q=where+is+the+statue+of+liberty
Statue of Liberty
Location: Liberty Island

http://www.google.com/search?q=where+is+cuba
Cuba
Location: Caribbean, island between the Caribbean Sea and the North Atlantic Ocean, 150 km south of Key West, ...

http://www.google.com/search?q=where+is+microsoft
Microsoft
Location: Redmond, Washington

This is a good game...

Q: When was Star Wars released?

Star Wars
Year: 1977

However, despite it telling me "The following words are very common and were not included in your search: When was" I actually get a different result for:

Q: Star Wars Released?

The Star Wars Trilogy Star Wars the Empire
Released: 25 October 1990

Hmm...

"Who is the queen of england?" gives "Queen Victoria", whereas the more correct "Who is the queen of the united kingdom?" gives "Elizabeth II". Abbreviating to "UK" doesn't work. "Who is the head of the commonwealth?" works (citing Wikipedia), though similar things I tried didn't.
