Problem: Glass:

Some people consider glass to be a liquid due to its lack of a first-order phase transition where certain thermodynamic variables such as volume, entropy and enthalpy are discontinuous through the glass transition range. The glass transition may be described as analogous to a second-order phase transition where the intensive thermodynamic variables such as the thermal expansivity and heat capacity are discontinuous. Nonetheless, the equilibrium theory of phase transformations does not entirely hold for glass, and hence the glass transition cannot be classed as one of the classical equilibrium phase transformations in solids.

Transition in heat is comparable to what?

Problem: By total area (water as well as land), the United States is either slightly larger or smaller than the People's Republic of China, making it the world's third or fourth largest country. China and the United States are smaller than Russia and Canada in total area, but are larger than Brazil. By land area only (exclusive of waters), the United States is the world's third largest country, after Russia and China, with Canada in fourth. Whether the US or China is the third largest country by total area depends on two factors: (1) The validity of China's claim on Aksai Chin and Trans-Karakoram Tract. Both these territories are also claimed by India, so are not counted; and (2) How US calculates its own surface area. Since the initial publishing of the World Factbook, the CIA has updated the total area of United States a number of times.
Which country is the worlds fourth largest?

General George Washington (173299) proved an excellent organizer and administrator, who worked successfully with Congress and the state governors, selecting and mentoring his senior officers, supporting and training his troops, and maintaining an idealistic Republican Army. His biggest challenge was logistics, since neither Congress nor the states had the funding to provide adequately for the equipment, munitions, clothing, paychecks, or even the food supply of the soldiers. As a battlefield tactician Washington was often outmaneuvered by his British counterparts. As a strategist, however, he had a better idea of how to win the war than they did. The British sent four invasion armies. Washington's strategy forced the first army out of Boston in 1776, and was responsible for the surrender of the second and third armies at Saratoga (1777) and Yorktown (1781). He limited the British control to New York and a few places while keeping Patriot control of the great majority of the population. The Loyalists, on whom the British had relied too heavily, comprised about 20% of the population but never were well organized. As the war ended, Washington watched proudly as the final British army quietly sailed out of New York City in November 1783, taking the Loyalist leadership with them. Washington astonished the world when, instead of seizing power, he retired quietly to his farm in Virginia.
What did Washington not do after defeating the British Army?
A: unanswerable

Context and question: The Latin alphabet of the time still lacked the letters j and w, and there was no v as distinct from u; moreover native Old English spellings did not use k, q or z. The remaining 20 Latin letters were supplemented by four more: (sc, modern ash) and (t, now called eth or edh), which were modified Latin letters, and thorn and wynn , which are borrowings from the futhorc. A few letter pairs were used as digraphs, representing a single sound. Also used was the Tironian note (a character similar to the digit 7) for the conjunction and, and a thorn with a crossbar through the ascender for the pronoun t. Macrons over vowels were originally used not to mark long vowels (as in modern editions), but to indicate stress, or as abbreviations for a following m or n.
What number was the Tironian note visually similar to?
Answer:

Question: The modern domesticated turkey is descended from one of six subspecies of wild turkey (Meleagris gallopavo) found in the present Mexican states of Jalisco, Guerrero and Veracruz. Pre-Aztec tribes in south-central Mexico first domesticated the bird around 800 BC, and Pueblo Indians inhabiting the Colorado Plateau in the United States did likewise around 200 BC. They used the feathers for robes, blankets, and ceremonial purposes. More than 1,000 years later, they became an important food source. The first Europeans to encounter the bird misidentified it as a guineafowl, a bird known as a "turkey fowl" at that time because it had been introduced into Europe via Turkey.
Is there an answer to this question: What other purposes have the domesticated turkey been used for aside from food?

Answer: feathers for robes, blankets, and ceremonial purposes

In the Islamic tradition, Mary and Jesus were the only children who could not be touched by Satan at the moment of their birth, for God imposed a veil between them and Satan. According to author Shabbir Akhtar, the Islamic perspective on Mary's Immaculate Conception is compatible with the Catholic doctrine of the same topic. "O People of the Book! Do not go beyond the bounds in your religion, and do not say anything of Allah but the truth. The Messiah, Jesus son of Mary, was but a Messenger of God, and a Word of His (Power) which He conveyed to Mary, and a spirit from Him. So believe in Allah (as the One, Unique God), and His Messengers (including Jesus, as Messenger); and do not say: (Allah is one of) a trinity. Give up (this assertion) a" (it is) for your own good (to do so). Allah is but One Allah ; All-Glorified He is in that He is absolutely above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And Allah suffices as the One to be relied on, to Whom affairs should be referred." Quran 4/171
