Problem: Red:

But early in the 16th century, a brilliant new red appeared in Europe. When the Spanish conquistador Hernán Cortés and his soldiers conquered the Aztec Empire in 1519-1521, they discovered slowly that the Aztecs had another treasure beside silver and gold; they had the tiny cochineal, a parasitic scale insect which lived on cactus plants, which, when dried and crushed, made a magnificent red. The cochineal in Mexico was closely related to the Kermes varieties of Europe, but unlike European Kermes, it could be harvested several times a year, and it was ten times stronger than the Kermes of Poland. It worked particularly well on silk, satin and other luxury textiles. In 1523 Cortes sent the first shipment to Spain. Soon cochineal began to arrive in European ports aboard convoys of Spanish galleons.

In what year did Cortes send the first cochineal to Spain?

A: 1523


Problem: For vertebrates, the early stages of neural development are similar across all species. As the embryo transforms from a round blob of cells into a wormlike structure, a narrow strip of ectoderm running along the midline of the back is induced to become the neural plate, the precursor of the nervous system. The neural plate folds inward to form the neural groove, and then the lips that line the groove merge to enclose the neural tube, a hollow cord of cells with a fluid-filled ventricle at the center. At the front end, the ventricles and cord swell to form three vesicles that are the precursors of the forebrain, midbrain, and hindbrain. At the next stage, the forebrain splits into two vesicles called the telencephalon (which will contain the cerebral cortex, basal ganglia, and related structures) and the diencephalon (which will contain the thalamus and hypothalamus). At about the same time, the hindbrain splits into the metencephalon (which will contain the cerebellum and pons) and the myelencephalon (which will contain the medulla oblongata). Each of these areas contains proliferative zones where neurons and glial cells are generated; the resulting cells then migrate, sometimes for long distances, to their final positions.
The thalamus and hypothalamus are contained in which vesicle?
---
Answer: the diencephalon


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Even during the war, Eritrea developed its transportation infrastructure by asphalting new roads, improving its ports, and repairing war-damaged roads and bridges as a part of the Warsay Yika'alo Program. The most significant of these projects was the construction of a coastal highway of more than 500 km connecting Massawa with Asseb, as well as the rehabilitation of the Eritrean Railway. The rail line has been restored between the port of Massawa and the capital Asmara, although services are sporadic. Steam locomotives are sometimes used for groups of enthusiasts.
What type of locomotives are sometimes used on the Eritrean Railway to cater to groups of enthusiasts?
A: Steam


Context and question: The High Middle Ages was the formative period in the history of the modern Western state. Kings in France, England, and Spain consolidated their power, and set up lasting governing institutions. New kingdoms such as Hungary and Poland, after their conversion to Christianity, became Central European powers. The Magyars settled Hungary around 900 under King Árpád (d. c. 907) after a series of invasions in the 9th century. The papacy, long attached to an ideology of independence from secular kings, first asserted its claim to temporal authority over the entire Christian world; the Papal Monarchy reached its apogee in the early 13th century under the pontificate of Innocent III (pope 1198–1216). Northern Crusades and the advance of Christian kingdoms and military orders into previously pagan regions in the Baltic and Finnic north-east brought the forced assimilation of numerous native peoples into European culture.
Who was king when the Magyars settled in Hungary?
Answer: Árpád


Question: After the Lisa's announcement, John Dvorak discussed rumors of a mysterious "MacIntosh" project at Apple in February 1983. The company announced the Macintosh 128K—manufactured at an Apple factory in Fremont, California—in October 1983, followed by an 18-page brochure included with various magazines in December. The Macintosh was introduced by a US$1.5 million Ridley Scott television commercial, "1984". It most notably aired during the third quarter of Super Bowl XVIII on January 22, 1984, and is now considered a "watershed event" and a "masterpiece." Regis McKenna called the ad "more successful than the Mac itself." "1984" used an unnamed heroine to represent the coming of the Macintosh (indicated by a Picasso-style picture of the computer on her white tank top) as a means of saving humanity from the "conformity" of IBM's attempts to dominate the computer industry. The ad alludes to George Orwell's novel, Nineteen Eighty-Four, which described a dystopian future ruled by a televised "Big Brother."
Is there an answer to this question: What did Regis McKenna call the "1984" ad that was aired during the Super Bowl?

Answer: "more successful than the Mac itself."


Washington University's sports teams are called the Bears. They are members of the National Collegiate Athletic Association and participate in the University Athletic Association at the Division III level. The Bears have won 19 NCAA Division III Championships— one in women's cross country (2011), one in men's tennis (2008), two in men's basketball (2008, 2009), five in women's basketball (1998–2001, 2010), and ten in women's volleyball (1989, 1991–1996, 2003, 2007, 2009) – and 144 UAA titles in 15 different sports. The Athletic Department is headed by John Schael who has served as director of athletics since 1978. The 2000 Division III Central Region winner of the National Association of Collegiate Directors of Athletics/Continental Airlines Athletics Director of the Year award, Schael has helped orchestrate the Bears athletics transformation into one of the top departments in Division III.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What sport did John Schael play when he was in college?
Ah, so..
unanswerable
