Problem: Middle Ages:

By the end of the 5th century the western section of the empire was divided into smaller political units, ruled by the tribes that had invaded in the early part of the century. The deposition of the last emperor of the west, Romulus Augustus, in 476 has traditionally marked the end of the Western Roman Empire.[E] The Eastern Roman Empire, often referred to as the Byzantine Empire after the fall of its western counterpart, had little ability to assert control over the lost western territories. The Byzantine emperors maintained a claim over the territory, but none of the new kings in the west dared to elevate himself to the position of emperor of the west, Byzantine control of most of the Western Empire could not be sustained; the reconquest of the Italian peninsula and Mediterranean periphery by Justinian (r. 527565) was the sole, and temporary, exception.

What is another name for the Eastern Roman Empire?

A: Byzantine Empire

Problem: In January 1964, Nasser called for an Arab League summit in Cairo to establish a unified Arab response against Israel's plans to divert the Jordan River's waters for economic purposes, which Syria and Jordan deemed an act of war. Nasser blamed Arab divisions for what he deemed "the disastrous situation". He discouraged Syria and Palestinian guerrillas from provoking the Israelis, conceding that he had no plans for war with Israel. During the summit, Nasser developed cordial relations with King Hussein, and ties were mended with the rulers of Saudi Arabia, Syria, and Morocco. In May, Nasser moved to formally share his leadership position over the Palestine issue by initiating the creation of the Palestine Liberation Organization (PLO). In practice, Nasser used the PLO to wield control over the Palestinian fedayeen. Its head was to be Ahmad Shukeiri, Nasser's personal nominee.
What organization was formed as a result of the talks?

Answer: Palestine Liberation Organization

In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.
Which company distributed the NES to the UK, Italy, and Australia?
A: Mattel

Context and question: Mahayana schools recognize all or part of the Mahayana Sutras.

A few of the sutras for Mahayanists became a manifestation of who?
Answer: the Buddha

Question: Albert assumed the regnal name "George VI" to emphasise continuity with his father and restore confidence in the monarchy. The beginning of George VI's reign was taken up by questions surrounding his predecessor and brother, whose titles, style and position were uncertain. He had been introduced as "His Royal Highness Prince Edward" for the abdication broadcast, but George VI felt that by abdicating and renouncing the succession Edward had lost the right to bear royal titles, including "Royal Highness". In settling the issue, George's first act as king was to confer upon his brother the title and style "His Royal Highness The Duke of Windsor", but the Letters Patent creating the dukedom prevented any wife or children from bearing royal styles. George VI was also forced to buy from Edward the royal residences of Balmoral Castle and Sandringham House, as these were private properties and did not pass to George VI automatically. Three days after his accession, on his 41st birthday, he invested his wife, the new queen consort, with the Order of the Garter.
Is there an answer to this question: What regnal name did Albert adopt?

Answer: George VI
