Input: Tucson, Arizona
Tucson's largest park, Reid Park, is located in midtown and includes Reid Park Zoo and Hi Corbett Field. Speedway Boulevard, a major east-west arterial road in central Tucson, was named the "ugliest street in America" by Life magazine in the early 1970s, quoting Tucson Mayor James Corbett. Despite this, Speedway Boulevard was awarded "Street of the Year" by Arizona Highways in the late 1990s. According to David Leighton, historical writer for the Arizona Daily Star newspaper, Speedway Boulevard derives its name from an old horse racetrack, known as "The Harlem River Speedway," more commonly called "The Speedway," in New York City. The street was called "The Speedway," from 1904 to about 1906 before the word "The" was taken out.

Article: The first Europeans to disembark and explore the region were the Portuguese navigators Diogo Cao in 1485 and Bartolomeu Dias in 1486; still the region was not claimed by the Portuguese crown. However, like most of Sub-Saharan Africa, Namibia was not extensively explored by Europeans until the 19th century, when traders and settlers arrived, principally from Germany and Sweden. In the late 19th century Dorsland trekkers crossed the area on their way from the Transvaal to Angola. Some of them settled in Namibia instead of continuing their journey.

Question: What nationality were the first navigators to explore Namibia come from?
Ans: Portuguese

Here is a question about this article: The essence of air defence is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account speed and direction of both the target and the projectile.
What is the answer to this question: What two things must be considered in regards to the projectile and target?
****
So... speed and direction

Nuclear surety ensures the safety, security and effectiveness of nuclear operations. Because of their political and military importance, destructive power, and the potential consequences of an accident or unauthorized act, nuclear weapons and nuclear weapon systems require special consideration and protection against risks and threats inherent in their peacetime and wartime environments. The Air Force, in conjunction with other entities within the Departments of Defense or Energy, achieves a high standard of protection through a stringent nuclear surety program. This program applies to materiel, personnel, and procedures that contribute to the safety, security, and control of nuclear weapons, thus assuring no nuclear accidents, incidents, loss, or unauthorized or accidental use (a Broken Arrow incident). The Air Force continues to pursue safe, secure and effective nuclear weapons consistent with operational requirements. Adversaries, allies, and the American people must be highly confident of the Air Force's ability to secure nuclear weapons from accidents, theft, loss, and accidental or unauthorized use. This day-to-day commitment to precise and reliable nuclear operations is the cornerstone of the credibility of the NDO mission. Positive nuclear command, control, communications; effective nuclear weapons security; and robust combat support are essential to the overall NDO function.
What other US departments does the Air Force coordinate with for nuclear security?
****
The answer: Departments of Defense or Energy

The economist F. A. Hayek analyzed how the Rule of Law might be beneficial to the free market. Hayek proposed that under the Rule of Law individuals would be able to make wise investments and future plans with some confidence in a successful return on investment when he stated: "under the Rule of Law the government is prevented from stultifying individual efforts by ad hoc action. Within the known rules of the game the individual is free to pursue his personal ends and desires, certain that the powers of government will not be used deliberately to frustrate his efforts."
