Problem: Portugal:

In 1348 and 1349 Portugal, like the rest of Europe, was devastated by the Black Death. In 1373, Portugal made an alliance with England, which is the longest-standing alliance in the world. This alliance served both nations' interests throughout history and is regarded by many as the predecessor to NATO. Over time this went way beyond geo-political and military cooperation (protecting both nations' interests in Africa, the Americas and Asia against French, Spanish and Dutch rivals) and maintained strong trade and cultural ties between the two old European allies. Particularly in the Oporto region, there is visible English influence to this day.

In 1373, Portugal made an alliance with which country?

A: England

Problem: Despite Laemmle's role as an innovator, he was an extremely cautious studio chief. Unlike rivals Adolph Zukor, William Fox, and Marcus Loew, Laemmle chose not to develop a theater chain. He also financed all of his own films, refusing to take on debt. This policy nearly bankrupted the studio when actor-director Erich von Stroheim insisted on excessively lavish production values for his films Blind Husbands (1919) and Foolish Wives (1922), but Universal shrewdly gained a return on some of the expenditure by launching a sensational ad campaign that attracted moviegoers. Character actor Lon Chaney became a drawing card for Universal in the 1920s, appearing steadily in dramas. His two biggest hits for Universal were The Hunchback of Notre Dame (1923) and The Phantom of the Opera (1925). During this period Laemmle entrusted most of the production policy decisions to Irving Thalberg. Thalberg had been Laemmle's personal secretary, and Laemmle was impressed by his cogent observations of how efficiently the studio could be operated. Promoted to studio chief, Thalberg was giving Universal's product a touch of class, but MGM's head of production Louis B. Mayer lured Thalberg away from Universal with a promise of better pay. Without his guidance Universal became a second-tier studio, and would remain so for several decades.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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.
What is the direction of transformations in energy?
A: what kind of energy is transformed to what other kind

Context and question: Larger SAMs may be deployed in fixed launchers, but can be towed/re-deployed at will. The SAMs launched by individuals are known in the United States as the Man-Portable Air Defence Systems (MANPADS). MANPADS of the former Soviet Union have been exported around the World, and can be found in use by many armed forces. Targets for non-ManPAD SAMs will usually be acquired by air-search radar, then tracked before/while a SAM is "locked-on" and then fired. Potential targets, if they are military aircraft, will be identified as friend or foe before being engaged. The developments in the latest and relatively cheap short-range missiles have begun to replace autocannons in this role.
What can be deployed in fixed launchers but re-deploy at will?
Answer: Larger SAMs

Question: According to the latest nationwide census, Roman Catholics constituted 30.8% of the total population of Germany, followed by the Evangelical Protestants at 30.3%. Other religions, atheists or not specified constituted 38.8% of the population at the time. Among "others" are Protestants not included in Evangelical Church of Germany, and other Christians such as the Restorationist New Apostolic Church. Protestantism was more common among the citizens of Germany. The North and East Germany is predominantly Protestant, the South and West rather Catholic. Nowadays there is a non-religious majority in Hamburg and the East German states.
Is there an answer to this question: What religion makes up 30.8% of Europe's population?

Answer: unanswerable

Problem: Han dynasty:

Women were expected to obey the will of their father, then their husband, and then their adult son in old age. However, it is known from contemporary sources that there were many deviations to this rule, especially in regard to mothers over their sons, and empresses who ordered around and openly humiliated their fathers and brothers. Women were exempt from the annual corvee labor duties, but often engaged in a range of income-earning occupations aside from their domestic chores of cooking and cleaning.

Which parental figures often avoided the common familial rules?
---
A:
mothers
