Problem: Multiracial Americans are Americans who have mixed ancestry of "two or more races". The term may also include Americans of mixed-race ancestry who self-identify with just one group culturally and socially (cf. the one-drop rule). In the 2010 US census, approximately 9 million individuals, or 2.9% of the population, self-identified as multiracial. There is evidence that an accounting by genetic ancestry would produce a higher number, but people live according to social and cultural identities, not DNA. Historical reasons, including slavery creating a racial caste and the European-American suppression of Native Americans, often led people to identify or be classified by only one ethnicity, generally that of the culture in which they were raised. Prior to the mid-20th century, many people hid their multiracial heritage because of racial discrimination against minorities. While many Americans may be biologically multiracial, they often do not know it or do not identify so culturally, any more than they maintain all the differing traditions of a variety of national ancestries.
What are people most likely to identify themselves as?
The answer is the following: the culture in which they were raised


The professionals soon displaced the amateur ex-Public schoolboys. Bermuda's role as the primary Royal Navy base in the Western Hemisphere, with an army garrison to match, ensured that the naval and military officers quickly introduced the newly formalised sports to Bermuda, including cricket, football, Rugby football, and even tennis and rowing (rowing did not adapt well from British rivers to the stormy Atlantic. The officers soon switched to sail racing, founding the Royal Bermuda Yacht Club). Once these sports reached Bermuda, they were eagerly adopted by Bermudians.
What happened to the Public schoolboys in these sports?
professionals soon displaced the amateur ex-Public schoolboys


Input: Pacific War
From early 1944 until the days leading up to the invasion, Kuribayashi transformed the island into a massive network of bunkers, hidden guns, and 11 mi (18 km) of underground tunnels. The heavy American naval and air bombardment did little but drive the Japanese further underground, making their positions impervious to enemy fire. Their pillboxes and bunkers were all connected so that if one was knocked out, it could be reoccupied again. The network of bunkers and pillboxes greatly favored the defender.

What were the pillboxes and bunkers connected by?
Output: underground tunnels


Input: Article: After the American Revolutionary War, the number and proportion of free people of color increased markedly in the North and the South as slaves were freed. Most northern states abolished slavery, sometimes, like New York, in programs of gradual emancipation that took more than two decades to be completed. The last slaves in New York were not freed until 1827. In connection with the Second Great Awakening, Quaker and Methodist preachers in the South urged slaveholders to free their slaves. Revolutionary ideals led many men to free their slaves, some by deed and others by will, so that from 1782 to 1810, the percentage of free people of color rose from less than one percent to nearly 10 percent of blacks in the South.

Now answer this question: What is it called when it takes several years for slaves to be freed in a program?

Output: gradual emancipation


Problem: 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.
What caused the constant linear velocity?
The answer is the following:
