In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

[Q]: Question: In which country is the seaport city of Porto located where the wine received its name "port"? Passage:Port is produced from grapes grown and processed in the demarcated Douro region. The wine produced is then fortified by the addition of a neutral grape spirit known as aguardente to stop the fermentation, leaving residual sugar in the wine, and to boost the alcohol content. The fortification spirit is sometimes referred to as brandy but it bears little resemblance to commercial brandies. The wine is then stored and aged, often in barrels stored in a Lodge (meaning "cellar") as is the case in Vila Nova de Gaia, before being bottled. The wine received its name, "port", in the later half of the 17th century from the seaport city of Porto at the mouth of the Douro River, where much of the product was brought to market or for export to other countries in Europe. The Douro valley where port wine is produced was defined and established as a protected region, and the name Douro thus an official appellation, in 1756, making it the third oldest, after Chianti (1716) and Tokaj (1730).

[Q]: Question: On what day was the inauguration of the president who held a ceremony on the banks of the scenic New River to designate it as an American Heritage River? Passage:Ashe County has been home to, produced, or been visited by, several prominent people. It is the hometown of Monte Weaver from Helton who pitched for the Washington Senators and pitched a World Series game in 1933. After being traded from the Senators, he pitched for the Boston Red Sox, before being called into service in World War II. Weaver died in 1994. Albert Hash a well-known and beloved fiddler and instrument maker at one time resided in Lansing. Helen Keller visited an Ashe County native, Marvin Osborne, in 1944 when he was wounded in France in World War II. Loretta Lynn sang at the Central Food Market in West Jefferson in the late 1960s (the Central Food building formally housed a locally owned auto parts store and is now the location of a local restaurant). Roni Stoneman was a visitor to Ashe Park in the 1980s. In 1998, then-President Bill Clinton and his Vice-President, Al Gore, held a ceremony on the banks of the scenic New River to designate it as an American Heritage River. After the ceremony, both men had lunch at the historic Glendale Springs Inn, also located in Ashe County. Fiddle player G. B. Grayson was born in Ashe County in 1887.

[Q]: Question: What country is the Platine region found within? Passage:The consumption of yerba mate became widespread in the Spanish colony of Paraguay in the late 16th century both among Spanish settlers and indigenous Guaraní people, who had to some extent consumed it before the Spanish arrival. Mate consumption spread in the 17th century to the Platine region and from there to Chile and Peru. This widespread consumption turned it into Paraguay’s main commodity above other wares like tobacco, and Indian labour was used to harvest wild stands. In the mid 17th century Jesuits managed to domesticate the plant and establish plantations in their Indian reductions in Misiones, sparking severe competition with the Paraguayan harvesters of wild stands. After the expulsion of the Jesuits in the 1770s their plantations fell into decay as did their domestication secrets. The industry continued to be of prime importance for the Paraguayan economy after independence, but development in benefit of the Paraguayan state halted after the Paraguayan War (1864–1870) which devastated the country both economically and demographically. Brazil then became the prime producer of yerba mate. In Brazilian and Argentine projects in late 19th and early 20th century the plant was domesticated once again opening the way for modern plantation systems. When Brazilian entrepreneurs turned their attention to coffee in the 1930s Argentina, which had long been the prime consumer, took over as the largest producer, resurrecting Misiones Province where the Jesuits had once had most of their plantations. However, the coffee production regions in Brazil are distinct from the mate plantations. According to FAO in 2012, Brazil is the biggest producer of mate in the world with 513,256 MT (58%), followed by Argentina with 290,000 MT (32%) and Paraguay with 85,490 MT (10%).
