Problem: Southern Europe:

The Reconquista of Portugal and Spain led to a series of oceanic explorations resulting in the Age of Discovery that established direct links with Africa, the Americas, and Asia, while religious wars continued to be fought in Europe, which ended in 1648 with the Peace of Westphalia. The Spanish crown maintained its hegemony in Europe and was the leading power on the continent until the signing of the Treaty of the Pyrenees, which ended a conflict between Spain and France that had begun during the Thirty Years' War. An unprecedented series of major wars and political revolutions took place around Europe and indeed the world in the period between 1610 and 1700. Observers at the time, and many historians since, have argued that wars caused the revolutions. Galileo Galilei, invented the telescope and the thermometer which allowed him to observe and describe the solar system. Leonardo da Vinci painted the most famous work in the world. Guglielmo Marconi invented the radio.

Which scientist developed a means of viewing space?

A: Galileo Galilei

Problem: The Legend of Zelda: Twilight Princess:

In four months, Aonuma's team managed to present realistic horseback riding,[l] which Nintendo later revealed to the public with a trailer at Electronic Entertainment Expo 2004. The game was scheduled to be released the next year, and was no longer a follow-up to The Wind Waker; a true sequel to it was released for the Nintendo DS in 2007, in the form of Phantom Hourglass. Miyamoto explained in interviews that the graphical style was chosen to satisfy demand, and that it better fit the theme of an older incarnation of Link. The game runs on a modified The Wind Waker engine.

When did the company release a trailer of the horseback riding aspect?
---
A: 2004

Problem: Washington University in St. Louis:

Over 50% of undergraduate students live on campus. Most of the residence halls on campus are located on the South 40, named because of its adjacent location on the south side of the Danforth Campus and its size of 40 acres (160,000 m2). It is the location of all the freshman buildings as well as several upperclassman buildings, which are set up in the traditional residential college system. All of the residential halls are co-ed. The South 40 is organized as a pedestrian-friendly environment wherein residences surround a central recreational lawn known as the Swamp. Bear's Den (the largest dining hall on campus), the Habif Health and Wellness Center (Student Health Services), the Residential Life Office, University Police Headquarters, various student-owned businesses (e.g. the laundry service, Wash U Wash), and the baseball, softball, and intramural fields are also located on the South 40.

Where are all freshman residence buildings at Washington University located?
---
A: the South 40

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
