TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: Universal's parent company purchased Universal from whom?, Context: Matsushita provided a cash infusion, but the clash of cultures was too great to overcome, and five years later Matsushita sold an 80% stake in MCA/Universal to Canadian drinks distributor Seagram for $5.7 billion. Seagram sold off its stake in DuPont to fund this expansion into the entertainment industry. Hoping to build an entertainment empire around Universal, Seagram bought PolyGram in 1999 and other entertainment properties, but the fluctuating profits characteristic of Hollywood were no substitute for the reliable income stream gained from the previously held shares in DuPont.

SOLUTION: Matsushita

PROBLEM: Which dance described is not synchronized?, Context: The Samoan word for dance is siva with unique gentle movements of the body in time to music and which tells a story, although the Samoan male dances can be more physical and snappy. The sasa is also a traditional dance where rows of dancers perform rapid synchronised movements in time to the rhythm of wooden drums (pate) or rolled mats. Another dance performed by males is called the fa'ataupati or the slap dance, creating rhythmic sounds by slapping different parts of the body. This is believed to have been derived from slapping insects on the body.

SOLUTION: fa'ataupati

PROBLEM: If we are not talking about zero average values, but different kind of values, what are we talking about?, Context: QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified.

SOLUTION:
variances
