Input: Article: 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.

Now answer this question: What must happen quickly for glass to form?

Output: cooling

Input: Article: During the three years following its inception, the university bore three different names. The board first approved "Eliot Seminary," but William Eliot was uncomfortable with naming a university after himself and objected to the establishment of a seminary, which would implicitly be charged with teaching a religious faith. He favored a nonsectarian university. In 1854, the Board of Trustees changed the name to "Washington Institute" in honor of George Washington. Naming the University after the nation's first president, only seven years before the American Civil War and during a time of bitter national division, was no coincidence. During this time of conflict, Americans universally admired George Washington as the father of the United States and a symbol of national unity. The Board of Trustees believed that the university should be a force of unity in a strongly divided Missouri. In 1856, the University amended its name to "Washington University." The university amended its name once more in 1976, when the Board of Trustees voted to add the suffix "in St. Louis" to distinguish the university from the nearly two dozen other universities bearing Washington's name.

Now answer this question: What name was selected by the Board of Trustees in 1854 for Washington University?

Output: Washington Institute

Input: Article: A party may claim that a treaty should be terminated, even absent an express provision, if there has been a fundamental change in circumstances. Such a change is sufficient if unforeseen, if it undermined the “essential basis” of consent by a party, if it radically transforms the extent of obligations between the parties, and if the obligations are still to be performed. A party cannot base this claim on change brought about by its own breach of the treaty. This claim also cannot be used to invalidate treaties that established or redrew political boundaries.[citation needed]

Now answer this question: In order to be considered a fundamental change, a change in circumstances must have been what at the time of the adoption of the treaty?

Output:
unforeseen
