By the turn of the 20th century, fears had begun to grow in Britain that it would no longer be able to defend the metropole and the entirety of the empire while at the same time maintaining the policy of "splendid isolation". Germany was rapidly rising as a military and industrial power and was now seen as the most likely opponent in any future war. Recognising that it was overstretched in the Pacific and threatened at home by the Imperial German Navy, Britain formed an alliance with Japan in 1902 and with its old enemies France and Russia in 1904 and 1907, respectively.

Which country did Britain ally with in 1902?
Answer: Japan

On 1 July 1967, BBC Two became the first television channel in Europe to broadcast regularly in colour, using the West German PAL system that is still in use today although being gradually superseded by digital systems. (BBC One and ITV began 625-line colour broadcasts simultaneously on 15 November 1969). Unlike other terrestrial channels, BBC Two does not have soap opera or standard news programming, but a range of programmes intended to be eclectic and diverse (although if a programme has high audience ratings it is often eventually repositioned to BBC One). The different remit of BBC2 allowed its first controller, Sir David Attenborough to commission the first heavyweight documentaries and documentary series such as Civilisation, The Ascent of Man and Horizon.
What kinds of programs did Attenborough favor?
documentaries


Input: Gramophone record
A different format, CD-4 (not to be confused with compact disc), by RCA, encoded the front-rear difference information on an ultrasonic carrier, which required a special wideband cartridge to capture it on carefully calibrated pickup arm/turntable combinations. CD-4 was even less successful than the two matrixed formats. (A further problem was that no cutting heads were available that could handle the HF information. That was remedied by cutting at half the speed. Later, the special half-speed cutting heads and equalization techniques were employed to get a wider frequency response in stereo with reduced distortion and greater headroom.)

How widespread was the success of CD-4 format? 
Output: even less successful than the two matrixed formats


Problem: Please answer a question about the following article about Multiracial American:
After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.
What is the effect of there no longer being a stigma on interracial marriage?
A:
more people are openly forming interracial unions
