Problem: Of the 80 torch-bearers in London, Sir Steve Redgrave, who started the relay, mentioned to the media that he had received e-mailed pleas to boycott the event and could "see why they would like to make an issue" of it. Francesca Martinez and Richard Vaughan refused to carry the torch, while Konnie Huq decided to carry it and also speak out against China. The pro-Tibetan Member of Parliament Norman Baker asked all bearers to reconsider. Amid pressure from both directions, Prime Minister Gordon Brown welcomed the torch outside 10 Downing Street without holding or touching it. The London relay saw the torch surrounded by what the BBC described as "a mobile protective ring." Protests began as soon as Redgrave started the event, leading to at least thirty-five arrests. In Ladbroke Grove a demonstrator attempted to snatch the torch from Konnie Huq in a momentary struggle, and in a separate incident, a fire extinguisher was set off near the torch. The Chinese ambassador carried the torch through Chinatown after an unpublicized change to the route amid security concerns. The torch made an unscheduled move onto a bus along Fleet Street amid security concerns and efforts to evade the protesters. In an effort to counter the pro-Tibet protesters and show their support for the 2008 Beijing Olympics, more than 2,000 Chinese also gathered on the torch route and demonstrated with signs, banners and Chinese flags. A large number of supporters were concentrated in Trafalgar Square, displaying the Olympic slogan "One World, One Dream".
How many torchbearers took part in the London route?
The answer is the following: 80

Problem: Please answer a question about the following article about Multiracial American:
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.
Why did muticultural Americans hid their heritage?
A:
many people hid their multiracial heritage because of racial discrimination against minorities
