Question: Tucson is located 118 mi (190 km) southeast of Phoenix and 60 mi (97 km) north of the United States - Mexico border. The 2010 United States Census puts the city's population at 520,116 with a metropolitan area population at 980,263. In 2009, Tucson ranked as the 32nd largest city and 52nd largest metropolitan area in the United States. A major city in the Arizona Sun Corridor, Tucson is the largest city in southern Arizona, the second largest in the state after Phoenix. It is also the largest city in the area of the Gadsden Purchase. As of 2015, The Greater Tucson Metro area has exceeded a population of 1 million.
Is there an answer to this question: What is Tucson's metro area population in 2010?

Question: The Federal War ended in 1863 with the signing of the Treaty of Coche by both the centralist government of the time and the Federal Forces. The United States of Venezuela were subsequently incorporated under a "Federation of Sovereign States" upon principles borrowed from the Articles of Confederation of the United States of America. In this Federation, each State had a "President" of its own that controlled almost every issue, even the creation of "State Armies," while the Federal Army was required to obtain presidential permission to enter any given state.
Is there an answer to this question: When did the federal war end?

Answer: 1863

Question: There do exist orbits within these empty regions where objects can survive for the age of the Solar System. These resonances occur when Neptune's orbital period is a precise fraction of that of the object, such as 1:2, or 3:4. If, say, an object orbits the Sun once for every two Neptune orbits, it will only complete half an orbit by the time Neptune returns to its original position. The most heavily populated resonance in the Kuiper belt, with over 200 known objects, is the 2:3 resonance. Objects in this resonance complete 2 orbits for every 3 of Neptune, and are known as plutinos because the largest of the known Kuiper belt objects, Pluto, is among them. Although Pluto crosses Neptune's orbit regularly, the 2:3 resonance ensures they can never collide. The 3:4, 3:5, 4:7 and 2:5 resonances are less populated.
Is there an answer to this question: What is the best known, and largest, object in the Kuiper belt?

Answer: Pluto

Question: The starch source in a beer provides the fermentable material and is a key determinant of the strength and flavour of the beer. The most common starch source used in beer is malted grain. Grain is malted by soaking it in water, allowing it to begin germination, and then drying the partially germinated grain in a kiln. Malting grain produces enzymes that convert starches in the grain into fermentable sugars. Different roasting times and temperatures are used to produce different colours of malt from the same grain. Darker malts will produce darker beers.
Is there an answer to this question: What material does the flavour source in beer provide?

Answer:
unanswerable
