Problem: Please answer a question about the following article about Glass:
Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilizations seem to have brought glass-making to a halt. Indigenous development of glass technology in South Asia may have begun in 1730 BCE. In ancient China, though, glassmaking seems to have a late start, compared to ceramics and metal work. The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, now in modern Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance. Glass objects have been recovered across the Roman empire in domestic, industrial and funerary contexts.[citation needed]
In what current country is Trier located?
A: Germany
Problem: Please answer a question about the following article about Nintendo Entertainment System:
Video output connections varied from one model of the console to the next. The original HVC-001 model of the Family Computer featured only radio frequency (RF) modulator output. When the console was released in North America and Europe, support for composite video through RCA connectors was added in addition to the RF modulator. The HVC-101 model of the Famicom dropped the RF modulator entirely and adopted composite video output via a proprietary 12-pin "multi-out" connector first introduced for the Super Famicom/Super Nintendo Entertainment System. Conversely, the North American re-released NES-101 model most closely resembled the original HVC-001 model Famicom, in that it featured RF modulator output only. Finally, the PlayChoice-10 utilized an inverted RGB video output.
The HVC-101 lost the RF and adopted which output for use in North America and Europe?
A: composite video
Problem: Please answer a question about the following article about Gamal Abdel Nasser:
The nationalization announcement was greeted very emotionally by the audience and, throughout the Arab world, thousands entered the streets shouting slogans of support. US ambassador Henry A. Byroade stated, "I cannot overemphasize [the] popularity of the Canal Company nationalization within Egypt, even among Nasser's enemies." Egyptian political scientist Mahmoud Hamad wrote that, prior to 1956, Nasser had consolidated control over Egypt's military and civilian bureaucracies, but it was only after the canal's nationalization that he gained near-total popular legitimacy and firmly established himself as the "charismatic leader" and "spokesman for the masses not only in Egypt, but all over the Third World". According to Aburish, this was Nasser's largest pan-Arab triumph at the time and "soon his pictures were to be found in the tents of Yemen, the souks of Marrakesh, and the posh villas of Syria". The official reason given for the nationalization was that funds from the canal would be used for the construction of the dam in Aswan. That same day, Egypt closed the canal to Israeli shipping.
What US ambassador spoke about the widespread support for Nasser's nationalization of the canal?
A: Henry A. Byroade
Problem: Please answer a question about the following article about Brain:
The first real progress toward a modern understanding of nervous function, though, came from the investigations of Luigi Galvani, who discovered that a shock of static electricity applied to an exposed nerve of a dead frog could cause its leg to contract. Since that time, each major advance in understanding has followed more or less directly from the development of a new technique of investigation. Until the early years of the 20th century, the most important advances were derived from new methods for staining cells. Particularly critical was the invention of the Golgi stain, which (when correctly used) stains only a small fraction of neurons, but stains them in their entirety, including cell body, dendrites, and axon. Without such a stain, brain tissue under a microscope appears as an impenetrable tangle of protoplasmic fibers, in which it is impossible to determine any structure. In the hands of Camillo Golgi, and especially of the Spanish neuroanatomist Santiago Ramon y Cajal, the new stain revealed hundreds of distinct types of neurons, each with its own unique dendritic structure and pattern of connectivity.
The tool that was invented to stain only a small fractions of neurons was called what?
A:
the Golgi stain
