Input: Read this: If the Spanish monarch ever refused in conscience to grant royal assent, a procedure similar to the Belgian handling of King Baudouin's objection would not be possible under the current constitution. If the sovereign were ever declared incapable of discharging royal authority, his or her powers would not be transferred to the Cabinet, pending the parliamentary appointment of a regency. Instead, the constitution mandates the next person of age in the line of succession would immediately become regent. Therefore, had Juan Carlos followed the Belgian example in 2005 or 2010, a declaration of incapacity would have transferred power to Felipe, then the heir apparent.
Question: Who is the current heir apparent to Juan Carlos?

Output: unanswerable


QUES: On the other hand, the crew on board the spaceship also perceives the observer as slowed down and flattened along the spaceship's direction of travel, because both are moving at very nearly the speed of light relative to each other. Because the outside universe appears flattened to the spaceship, the crew perceives themselves as quickly traveling between regions of space that (to the stationary observer) are many light years apart. This is reconciled by the fact that the crew's perception of time is different from the stationary observer's; what seems like seconds to the crew might be hundreds of years to the stationary observer. In either case, however, causality remains unchanged: the past is the set of events that can send light signals to an entity and the future is the set of events to which an entity can send light signals.

Where does the future appear flattened and slowed according to the crew?
What is the answer?
ANS: unanswerable


QUES: Nicholas Lezard described post-punk as "a fusion of art and music". The era saw the robust appropriation of ideas from literature, art, cinema, philosophy, politics and critical theory into musical and pop cultural contexts. Artists sought to refuse the common distinction between high and low culture and returned to the art school tradition found in the work of artists such as Captain Beefheart and David Bowie. Among major influences on a variety of post-punk artists were writers such as William S. Burroughs and J.G. Ballard, avant-garde political scenes such as Situationism and Dada, and intellectual movements such as postmodernism. Many artists viewed their work in explicitly political terms. Additionally, in some locations, the creation of post-punk music was closely linked to the development of efficacious subcultures, which played important roles in the production of art, multimedia performances, fanzines and independent labels related to the music. Many post-punk artists maintained an anti-corporatist approach to recording and instead seized on alternate means of producing and releasing music. Journalists also became an important element of the culture, and popular music magazines and critics became immersed in the movement.
How did Nicholas Lezard describe post-punk?

ANS: fusion of art and music


The city's population increased more than sixfold during the first half of the 20th century, fed largely by an influx of European, Middle Eastern (Lebanese, Assyrian/Chaldean), and Southern migrants to work in the burgeoning automobile industry. In 1940, Whites were 90.4% of the city's population. Since 1950 the city has seen a major shift in its population to the suburbs. In 1910, fewer than 6,000 blacks called the city home; in 1930 more than 120,000 blacks lived in Detroit. The thousands of African Americans who came to Detroit were part of the Great Migration of the 20th century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the movement of blacks to northern cities called?
Ah, so.. Great Migration


Question: The Houston area is a leading center for building oilfield equipment. Much of its success as a petrochemical complex is due to its busy ship channel, the Port of Houston. In the United States, the port ranks first in international commerce and tenth among the largest ports in the world. Unlike most places, high oil and gasoline prices are beneficial for Houston's economy, as many of its residents are employed in the energy industry. Houston is the beginning or end point of numerous oil, gas, and products pipelines:
Try to answer this question if possible: Where does Houston rate in the size ranking of world ports?
Answer: tenth


Problem: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinum–iridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 – the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems – it is known that over such a timescale the many similar Pt–Ir alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
What kind of alloy is never used to measure a kilogram?
