Problem: Victoria visited mainland Europe regularly for holidays. In 1889, during a stay in Biarritz, she became the first reigning monarch from Britain to set foot in Spain when she crossed the border for a brief visit. By April 1900, the Boer War was so unpopular in mainland Europe that her annual trip to France seemed inadvisable. Instead, the Queen went to Ireland for the first time since 1861, in part to acknowledge the contribution of Irish regiments to the South African war. In July, her second son Alfred ("Affie") died; "Oh, God! My poor darling Affie gone too", she wrote in her journal. "It is a horrible year, nothing but sadness & horrors of one kind & another."
What year did Queen Victoria last set foot in Spain?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Noteworthy Irish mandolinists include Andy Irvine (who, like Johnny Moynihan, almost always tunes the top E down to D, to achieve an open tuning of GDAD), Paul Brady, Mick Moloney, Paul Kelly and Claudine Langille. John Sheahan and the late Barney McKenna, respectively fiddle player and tenor banjo player with The Dubliners, are also accomplished Irish mandolin players. The instruments used are either flat-backed, oval hole examples as described above (made by UK luthier Roger Bucknall of Fylde Guitars), or carved-top, oval hole instruments with arched back (made by Stefan Sobell in Northumberland). The Irish guitarist Rory Gallagher often played the mandolin on stage, and he most famously used it in the song "Going To My Hometown."
What Irish guitarist played the mandolin off stage?
A: unanswerable

Context and question: In 1943, at the age of 16, Elizabeth undertook her first solo public appearance on a visit to the Grenadier Guards, of which she had been appointed colonel the previous year. As she approached her 18th birthday, parliament changed the law so that she could act as one of five Counsellors of State in the event of her father's incapacity or absence abroad, such as his visit to Italy in July 1944. In February 1945, she joined the Women's Auxiliary Territorial Service as an honorary second subaltern with the service number of 230873. She trained as a driver and mechanic and was promoted to honorary junior commander five months later.
At what age was Elizabeth when she went on her first solo public appearance?
Answer: 16

Question: The U.S. Digital Millennium Copyright Act (1998) and the European E-Commerce Directive (2000) provide online intermediaries with limited statutory immunity from liability for copyright infringement. Online intermediaries hosting content that infringes copyright are not liable, so long as they do not know about it and take actions once the infringing content is brought to their attention. In U.S. law this is characterized as "safe harbor" provisions. Under European law, the governing principles for Internet Service Providers are "mere conduit", meaning that they are neutral 'pipes' with no knowledge of what they are carrying; and 'no obligation to monitor' meaning that they cannot be given a general mandate by governments to monitor content. These two principles are a barrier for certain forms of online copyright enforcement and they were the reason behind an attempt to amend the European Telecoms Package in 2009 to support new measures against copyright infringement.
Is there an answer to this question: In the E.U., what aren't the governing principles for ISP's?

Answer: unanswerable

Problem: Anti-aircraft warfare:

Anti-aircraft warfare or counter-air defence is defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action." They include ground-and air-based weapon systems, associated sensor systems, command and control arrangements and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries the main effort has tended to be 'homeland defence'. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence as are initiatives to adapt air defence to the task of intercepting any projectile in flight.

What is the primary effort been for most countries when it comes to anti-aircraft warfare?

A:
homeland defence
