Problem: Assure/Dissuade/Deter is a mission set derived from the Air Force's readiness to carry out the nuclear strike operations mission as well as from specific actions taken to assure allies as a part of extended deterrence. Dissuading others from acquiring or proliferating WMD, and the means to deliver them, contributes to promoting security and is also an integral part of this mission. Moreover, different deterrence strategies are required to deter various adversaries, whether they are a nation state, or non-state/transnational actor. The Air Force maintains and presents credible deterrent capabilities through successful visible demonstrations and exercises which assure allies, dissuade proliferation, deter potential adversaries from actions that threaten US national security or the populations and deployed military forces of the US, its allies and friends.
What is the US Air Force prepared to do to support its allies?

Answer: carry out the nuclear strike operations mission

Charleston is known for its unique culture, which blends traditional Southern U.S., English, French, and West African elements. The downtown peninsula has gained a reputation for its art, music, local cuisine, and fashion. Spoleto Festival USA, held annually in late spring, has become one of the world's major performing arts festivals. It was founded in 1977 by Pulitzer Prize-winning composer Gian Carlo Menotti, who sought to establish a counterpart to the Festival dei Due Mondi (the Festival of Two Worlds) in Spoleto, Italy.
What  the profession of Gian Carlo Menotti?
A: composer


Context and question: The 18th century saw a huge growth in the number of drinking establishments, primarily due to the introduction of gin. Gin was brought to England by the Dutch after the Glorious Revolution of 1688 and became very popular after the government created a market for "cuckoo grain" or "cuckoo malt" that was unfit to be used in brewing and distilling by allowing unlicensed gin and beer production, while imposing a heavy duty on all imported spirits. As thousands of gin-shops sprang up all over England, brewers fought back by increasing the number of alehouses. By 1740 the production of gin had increased to six times that of beer and because of its cheapness it became popular with the poor, leading to the so-called Gin Craze. Over half of the 15,000 drinking establishments in London were gin shops.
In what year did the Glorious Revolution occur?
Answer: 1688


Question: Uranium-238 is the most stable isotope of uranium, with a half-life of about 4.468×109 years, roughly the age of the Earth. Uranium-235 has a half-life of about 7.13×108 years, and uranium-234 has a half-life of about 2.48×105 years. For natural uranium, about 49% of its alpha rays are emitted by each of 238U atom, and also 49% by 234U (since the latter is formed from the former) and about 2.0% of them by the 235U. When the Earth was young, probably about one-fifth of its uranium was uranium-235, but the percentage of 234U was probably much lower than this.
Is there an answer to this question: What isotope of uranium has the most stability?

Answer: Uranium-238


Symmetry groups are groups consisting of symmetries of given mathematical objects—be they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions. Conceptually, group theory can be thought of as the study of symmetry.t[›] Symmetries in mathematics greatly simplify the study of geometrical or analytical objects. A group is said to act on another mathematical object X if every group element performs some operation on X compatibly to the group law. In the rightmost example below, an element of order 7 of the (2,3,7) triangle group acts on the tiling by permuting the highlighted warped triangles (and the other ones, too). By a group action, the group pattern is connected to the structure of the object being acted on.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can regarded as the study of symmetry?
Ah, so..
group theory
