Problem: Please answer a question about the following article about High-definition television:
These first European HDTV broadcasts used the 1080i format with MPEG-2 compression on a DVB-S signal from SES's Astra 1H satellite. Euro1080 transmissions later changed to MPEG-4/AVC compression on a DVB-S2 signal in line with subsequent broadcast channels in Europe.
What signal did Euro1080 later change to?
A: DVB-S2
Problem: Please answer a question about the following article about Florida:
From 1952 to 1964, most voters were registered Democrats, but the state voted for the Republican presidential candidate in every election except for 1964. The following year, Congress passed and President Lyndon B. Johnson signed the Voting Rights Act of 1965, providing for oversight of state practices and enforcement of constitutional voting rights for African Americans and other minorities in order to prevent the discrimination and disenfranchisement that had excluded most of them for decades from the political process.
what president signed the voting right act
A: President Lyndon B. Johnson signed the Voting Rights Act of 1965
Problem: Please answer a question about the following article about Nutrition:
The list of nutrients that people are known to require is, in the words of Marion Nestle, "almost certainly incomplete". As of 2014, nutrients are thought to be of two types: macro-nutrients which are needed in relatively large amounts, and micronutrients which are needed in smaller quantities. A type of carbohydrate, dietary fiber, i.e. non-digestible material such as cellulose, is required, for both mechanical and biochemical reasons, although the exact reasons remain unclear. Other micronutrients include antioxidants and phytochemicals, which are said to influence (or protect) some body systems. Their necessity is not as well established as in the case of, for instance, vitamins.
What is notable about cellulose in humans?
A: non-digestible
Problem: Please answer a question about the following article about Geological history of Earth:
The Jurassic Period extends from about 201.3 0.2 to 145.0 Ma. During the early Jurassic, the supercontinent Pangaea broke up into the northern supercontinent Laurasia and the southern supercontinent Gondwana; the Gulf of Mexico opened in the new rift between North America and what is now Mexico's Yucatan Peninsula. The Jurassic North Atlantic Ocean was relatively narrow, while the South Atlantic did not open until the following Cretaceous Period, when Gondwana itself rifted apart. The Tethys Sea closed, and the Neotethys basin appeared. Climates were warm, with no evidence of glaciation. As in the Triassic, there was apparently no land near either pole, and no extensive ice caps existed. The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of the continent was submerged under shallow tropical seas; famous locales include the Jurassic Coast World Heritage Site and the renowned late Jurassic lagerstatten of Holzmaden and Solnhofen. In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface. Though the epicontinental Sundance Sea left marine deposits in parts of the northern plains of the United States and Canada during the late Jurassic, most exposed sediments from this period are continental, such as the alluvial deposits of the Morrison Formation. The first of several massive batholiths were emplaced in the northern Cordillera beginning in the mid-Jurassic, marking the Nevadan orogeny. Important Jurassic exposures are also found in Russia, India, South America, Japan, Australasia and the United Kingdom.
The Gulf of Mexico formed in the rift between North America and what other land mass?
A:
Mexico's Yucatan Peninsula
