Question: Extract the answer to the question from the following context. Question: Who gave up Angola? Context: Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and/or personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975. By 2007, Portugal had 10,617,575 inhabitants of whom about 332,137 were legal immigrants.
Answer: Portugal

[Q]: Extract the answer to the question from the following context. Question: What can fire do to a sapwood? Context: It is remarkable that the inner heartwood of old trees remains as sound as it usually does, since in many cases it is hundreds, and in a few instances thousands, of years old. Every broken limb or root, or deep wound from fire, insects, or falling timber, may afford an entrance for decay, which, once started, may penetrate to all parts of the trunk. The larvae of many insects bore into the trees and their tunnels remain indefinitely as sources of weakness. Whatever advantages, however, that sapwood may have in this connection are due solely to its relative age and position.

[A]: afford an entrance for decay

input: Please answer the following: Extract the answer to the question from the following context. Question: Which happened first: the downtown skyscraper closed, or the Northland Center opened? Context: After World War II Hudson's realized that the limited parking space at its downtown skyscraper would increasingly be a problem for its customers. The solution in 1954 was to open the Northland Center in nearby Southfield, just beyond the city limits. It was the largest suburban shopping center in the world, and quickly became the main shopping destination for northern and western Detroit, and for much of the suburbs. By 1961 the downtown skyscraper accounted for only half of Hudson's sales; it closed in 1986. The Northland Center Hudson's, rebranded Macy's in 2006 following acquisition by Federated Department Stores, was closed along with the remaining stores in the center in March 2015 due to the mall's high storefront vacancy, decaying infrastructure, and financial mismanagement.

Context: The modern Greek theatre was born after the Greek independence, in the early 19th century, and initially was influenced by the Heptanesean theatre and melodrama, such as the Italian opera. The Nobile Teatro di San Giacomo di Corfu was the first theatre and opera house of modern Greece and the place where the first Greek opera, Spyridon Xyndas' The Parliamentary Candidate (based on an exclusively Greek libretto) was performed. During the late 19th and early 20th century, the Athenian theatre scene was dominated by revues, musical comedies, operettas and nocturnes and notable playwrights included Spyridon Samaras, Dionysios Lavrangas, Theophrastos Sakellaridis and others.

Problem: Extract the answer to the question from the following context. Question: Why was the Macintosh's memory problem a serious issue? Context: The Macintosh's minimal memory became apparent, even compared with other personal computers in 1984, and could not be expanded easily. It also lacked a hard disk drive or the means to easily attach one. Many small companies sprang up to address the memory issue. Suggestions revolved around either upgrading the memory to 512 KB or removing the computer's 16 memory chips and replacing them with larger-capacity chips, a tedious and difficult operation. In October 1984, Apple introduced the Macintosh 512K, with quadruple the memory of the original, at a price of US$3,195. It also offered an upgrade for 128k Macs that involved replacing the logic board.

A: could not be expanded easily

Context: The College Dropout was eventually issued by Roc-A-Fella in February 2004, shooting to number two on the Billboard 200 as his debut single, "Through the Wire" peaked at number fifteen on the Billboard Hot 100 chart for five weeks. "Slow Jamz", his second single featuring Twista and Jamie Foxx, became an even bigger success: it became the three musicians' first number one hit. The College Dropout received near-universal critical acclaim from contemporary music critics, was voted the top album of the year by two major music publications, and has consistently been ranked among the great hip-hop works and debut albums by artists. "Jesus Walks", the album's fourth single, perhaps exposed West to a wider audience; the song's subject matter concerns faith and Christianity. The song nevertheless reached the top 20 of the Billboard pop charts, despite industry executives' predictions that a song containing such blatant declarations of faith would never make it to radio. The College Dropout would eventually be certified triple platinum in the US, and garnered West 10 Grammy nominations, including Album of the Year, and Best Rap Album (which it received). During this period, West also founded GOOD Music, a record label and management company that would go on to house affiliate artists and producers, such as No I.D. and John Legend. At the time, the focal point of West's production style was the use of sped-up vocal samples from soul records. However, partly because of the acclaim of The College Dropout, such sampling had been much copied by others; with that overuse, and also because West felt he had become too dependent on the technique, he decided to find a new sound.

output:
triple platinum
