Input: Article: One early attempt at lengthening the playing time should be mentioned. At least one manufacturer in the early 1920s, World Records, produced records that played at a constant linear velocity, controlled by Noel Pemberton Billing's patented add-on governor device. As these were played from the outside to the inside, the rotational speed of the records increased as reproduction progressed. This action is similar (although in reverse) to that on the modern compact disc and the CLV version of its predecessor, the Philips Laser Disc.

Now answer this question: What caused the constant linear velocity?

Output: Noel Pemberton Billing's patented add-on governor device

Input: Article: From the 1930s through much of the 1960s, Florida was essentially a one-party state dominated by white conservative Democrats, who together with other Democrats of the Solid South, exercised considerable control in Congress. They gained federal money from national programs; like other southern states, Florida residents have received more federal monies than they pay in taxes: the state is a net beneficiary. Since the 1970s, the conservative white majority of voters in the state has largely shifted from the Democratic to the Republican Party. It has continued to support Republican presidential candidates through the 20th century, except in 1976 and 1996, when the Democratic nominee was from the South. They have had "the luxury of voting for presidential candidates who pledge to cut taxes and halt the expansion of government while knowing that their congressional delegations will continue to protect federal spending."

Now answer this question: What do these candidates that Florida supports pledge

Output: the luxury of voting for presidential candidates who pledge to cut taxes and halt the expansion of government

Input: Article: 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.

Now answer this question: How many inhabitants did Portugal have by 2007?

Output:
10,617,575
