Early Asian immigrants experienced prejudice and discrimination in the forms of not having the ability to become naturalized citizens. They also struggled with many of the same school segregation laws that African Americans faced. Particularly, during World War II, Japanese Americans were interned in camps and lost their property, homes, and businesses. Discrimination against Asians began with the Chinese Exclusion Act of 1882 and then continued with the Scott Act of 1888 and the Geary Act of 1892. At the beginning of the 20th century, the United States passed the Immigration Act of 1924 to prevent Asian immigration out of fear that Asians were stealing white jobs and lowering the standard for wages. In addition, whites and non-Asians do not differentiate among the different Asian groups and perpetuate the "model minority" stereotype. According to a 2010 article by Professor Qin Zhang of Fairfield University, Asians are characterized as one dimensional in having great work ethic and valuing education, but lacking in communication skills and personality. A negative outcome of this stereotype is that Asians have been portrayed as having poor leadership and interpersonal skills. This has contributing to the "glass ceiling" phenomenon in which although there are many qualified Asian Americans, they occupy a disproportionately small number of executive positions in businesses. Furthermore, the model minority stereotype has led to resentment of Asian success and several universities and colleges have limited or have been accused of limiting Asian matriculation.
Which bill was passed in an attempt to provide for Asian immigration?
A: unanswerable

Question: Lemi Ponifasio is a director and choreographer who is prominent internationally with his dance Company MAU. Neil Ieremia's company Black Grace has also received international acclaim with tours to Europe and New York. Hip hop has had a significant impact on Samoan culture. According to Katerina Martina Teaiwa, PhD from the University of Hawaii at Manoa, "Hip hop culture in particular is popular amongst Samoan youth." Like very many other countries, hip hop music is popular. In addition, the integration of hip hop elements into Samoan tradition also "testifies to the transferability of the dance forms themselves," and to the "circuits through which people and all their embodied knowledge travel." Dance both in its traditional form and its more modern forms has remained a central cultural currency to Samoans, especially youths.
Is there an answer to this question: What has Neil Leremia's company MAU recieved when touring in Europe and NY?

Answer: unanswerable

The opening years of the 1980s saw a number of changes in personnel and direction of established hard rock acts, including the deaths of Bon Scott, the lead singer of AC/DC, and John Bonham, drummer with Led Zeppelin. Whereas Zeppelin broke up almost immediately afterwards, AC/DC pressed on, recording the album Back in Black (1980) with their new lead singer, Brian Johnson. It became the fifth-highest-selling album of all time in the US and the second-highest-selling album in the world. Black Sabbath had split with original singer Ozzy Osbourne in 1979 and replaced him with Ronnie James Dio, formerly of Rainbow, giving the band a new sound and a period of creativity and popularity beginning with Heaven and Hell (1980). Osbourne embarked on a solo career with Blizzard of Ozz (1980), featuring American guitarist Randy Rhoads. Some bands, such as Queen, moved away from their hard rock roots and more towards pop rock, while others, including Rush with Moving Pictures (1981), began to return to a hard rock sound. The creation of thrash metal, which mixed heavy metal with elements of hardcore punk from about 1982, particularly by Metallica, Anthrax, Megadeth and Slayer, helped to create extreme metal and further remove the style from hard rock, although a number of these bands or their members would continue to record some songs closer to a hard rock sound. Kiss moved away from their hard rock roots toward pop metal: firstly removing their makeup in 1983 for their Lick It Up album, and then adopting the visual and sound of glam metal for their 1984 release, Animalize, both of which marked a return to commercial success. Pat Benatar was one of the first women to achieve commercial success in hard rock, with three successive Top 5 albums between 1980 and 1982.
What singer replaced Ozzy Osbourne in Black Sabbath?
A:
Ronnie James Dio
