Problem: In physics, the standard definition of a glass (or vitreous solid) is a solid formed by rapid melt quenching. The term glass is often used to describe any amorphous solid that exhibits a glass transition temperature Tg. If the cooling is sufficiently rapid (relative to the characteristic crystallization time) then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at Tg. The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory. Generally, the structure of a glass exists in a metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline analogue of the amorphous phase.
What predicts glass-forming ability?
The answer is the following: rigidity theory

Problem: In 1975, a group of Chicago Cubs fans based in Washington, D.C. formed the Emil Verban Society. The society is a select club of high profile Cub fans, currently headed by Illinois Senator Dick Durbin which is named for Emil Verban, who in three seasons with the Cubs in the 1940s batted .280 with 39 runs batted in and one home run. Verban was picked as the epitome of a Cub player, explains columnist George Will, because "He exemplified mediocrity under pressure, he was competent but obscure and typifying of the work ethics." Verban initially believed he was being ridiculed, but his ill feeling disappeared several years later when he was flown to Washington to meet President Ronald Reagan, also a society member, at the White House. Hillary Clinton, Jim Belushi, Joe Mantegna, Rahm Emanuel, Dick Cheney and many others have been included among its membership.
What year did a group of Chicago Cubs fans form the Emil Verban Society?
The answer is the following: 1975

Problem: Victoria married her first cousin, Prince Albert of Saxe-Coburg and Gotha, in 1840. Their nine children married into royal and noble families across the continent, tying them together and earning her the sobriquet "the grandmother of Europe". After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, republicanism temporarily gained strength, but in the latter half of her reign her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration.
What was the name of Victoria's husband?
The answer is the following: Prince Albert

Problem: Uranium metal reacts with almost all non-metal elements (with an exception of the noble gases) and their compounds, with reactivity increasing with temperature. Hydrochloric and nitric acids dissolve uranium, but non-oxidizing acids other than hydrochloric acid attack the element very slowly. When finely divided, it can react with cold water; in air, uranium metal becomes coated with a dark layer of uranium oxide. Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.
What reacts with finely divided uranium?
The answer is the following:
cold water
