Problem: Asphalt:

A number of technologies allow asphalt/bitumen to be mixed at much lower temperatures. These involve mixing with petroleum solvents to form "cutbacks" with reduced melting point, or mixtures with water to turn the asphalt/bitumen into an emulsion. Asphalt emulsions contain up to 70% asphalt/bitumen and typically less than 1.5% chemical additives. There are two main types of emulsions with different affinity for aggregates, cationic and anionic. Asphalt emulsions are used in a wide variety of applications. Chipseal involves spraying the road surface with asphalt emulsion followed by a layer of crushed rock, gravel or crushed slag. Slurry seal involves the creation of a mixture of asphalt emulsion and fine crushed aggregate that is spread on the surface of a road. Cold-mixed asphalt can also be made from asphalt emulsion to create pavements similar to hot-mixed asphalt, several inches in depth and asphalt emulsions are also blended into recycled hot-mix asphalt to create low-cost pavements.

Less than 5% of asphalt emulsions is comprised of what?

Problem: Indoors, neoclassicism made a discovery of the genuine classic interior, inspired by the rediscoveries at Pompeii and Herculaneum. These had begun in the late 1740s, but only achieved a wide audience in the 1760s, with the first luxurious volumes of tightly controlled distribution of Le Antichità di Ercolano (The Antiquities of Herculaneum). The antiquities of Herculaneum showed that even the most classicising interiors of the Baroque, or the most "Roman" rooms of William Kent were based on basilica and temple exterior architecture turned outside in, hence their often bombastic appearance to modern eyes: pedimented window frames turned into gilded mirrors, fireplaces topped with temple fronts.
What rediscoveries inspired interior designs of neoclassicism?

Answer: Pompeii and Herculaneum.


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The conflict in northern Mali began in January 2012 with radical Islamists (affiliated to al-Qaeda) advancing into northern Mali. The Malian government had a hard time maintaining full control over their country. The fledgling government requested support from the international community on combating the Islamic militants. In January 2013, France intervened on behalf of the Malian government's request and deployed troops into the region. They launched Operation Serval on 11 January 2013, with the hopes of dislodging the al-Qaeda affiliated groups from northern Mali.
On whose behalf did the Malian government intervene?
A: unanswerable


Context and question: Although some earlier unpublished studies had been prepared, not until the early 1970s was true textual criticism applied to the Book of Mormon. At that time BYU Professor Ellis Rasmussen and his associates were asked by the LDS Church to begin preparation for a new edition of the Holy Scriptures. One aspect of that effort entailed digitizing the text and preparing appropriate footnotes, another aspect required establishing the most dependable text. To that latter end, Stanley R. Larson (a Rasmussen graduate student) set about applying modern text critical standards to the manuscripts and early editions of the Book of Mormon as his thesis project – which he completed in 1974. To that end, Larson carefully examined the Original Manuscript (the one dictated by Joseph Smith to his scribes) and the Printer’s Manuscript (the copy Oliver Cowdery prepared for the Printer in 1829–1830), and compared them with the 1st, 2nd, and 3rd editions of the Book of Mormon to determine what sort of changes had occurred over time and to make judgments as to which readings were the most original. Larson proceeded to publish a useful set of well-argued articles on the phenomena which he had discovered. Many of his observations were included as improvements in the 1981 LDS edition of the Book of Mormon.
What church did not want a new edition of the holy scriptures? 
Answer: unanswerable


Question: While full-time work hinders schooling, empirical evidence is varied on the relationship between part-time work and school. Sometimes even part-time work may hinder school attendance or performance. On the other hand, many poor children work for resources to attend school. Children who are not doing well at school sometimes seek more satisfactory experience in work. Good relations with a supervisor at work can provide relief from tensions that children feel at school and home. In the modern world, school education has become so central to society that schoolwork has become the dominant work for most children, often replacing participation in productive work. If school curricula or quality do not provide children with appropriate skills for available jobs or if children do nor have the aptitude for schoolwork, school may impede the learning of skills, such as agriculture, which will become necessary for future livelihood.
Is there an answer to this question: What hinders schooling for child labourers?

Answer: full-time work


There are strict limits to how efficiently heat can be converted into work in a cyclic process, e.g. in a heat engine, as described by Carnot's theorem and the second law of thermodynamics. However, some energy transformations can be quite efficient. The direction of transformations in energy (what kind of energy is transformed to what other kind) is often determined by entropy (equal energy spread among all available degrees of freedom) considerations. In practice all energy transformations are permitted on a small scale, but certain larger transformations are not permitted because it is statistically unlikely that energy or matter will randomly move into more concentrated forms or smaller spaces.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): what is non-equal energy spread among all available degrees of freedom
Ah, so..
