Problem: Compact disc:

Replicated CDs are mass-produced initially using a hydraulic press. Small granules of heated raw polycarbonate plastic are fed into the press. A screw forces the liquefied plastic into the mold cavity. The mold closes with a metal stamper in contact with the disc surface. The plastic is allowed to cool and harden. Once opened, the disc substrate is removed from the mold by a robotic arm, and a 15 mm diameter center hole (called a stacking ring) is created. The time it takes to "stamp" one CD is usually two to three seconds.

What is the term for the center hole in a CD?

A: stacking ring

Problem: The Pocitos district, near the beach of the same name, has many homes built by Bello and Reboratti between 1920 and 1940, with a mixture of styles. Other landmarks in Pocitos are the "Edificio Panamericano" designed by Raul Sichero, and the "Positano" and "El Pilar" designed by Adolfo Sommer Smith and Luis Garcia Pardo in the 1950s and 1960s. However, the construction boom of the 1970s and 1980s transformed the face of this neighbourhood, with a cluster of modern apartment buildings for upper and upper middle class residents.[citation needed]
Who designed the Edificio Panamericano?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In Johannine "agent Christology" the submission of Jesus to crucifixion is a sacrifice made as an agent of God or servant of God, for the sake of eventual victory. This builds on the salvific theme of the Gospel of John which begins in John 1:29 with John the Baptist's proclamation: "The Lamb of God who takes away the sins of the world". Further reinforcement of the concept is provided in Revelation 21:14 where the "lamb slain but standing" is the only one worthy of handling the scroll (i.e. the book) containing the names of those who are to be saved.
How is Resurrection detailed in the book of Revelations?
A: lamb slain but standing

Context and question: Even non-theist views about gods vary. Some non-theists avoid the concept of God, whilst accepting that it is significant to many; other non-theists understand God as a symbol of human values and aspirations. The nineteenth-century English atheist Charles Bradlaugh declared that he refused to say "There is no God", because "the word 'God' is to me a sound conveying no clear or distinct affirmation"; he said more specifically that he disbelieved in the Christian god. Stephen Jay Gould proposed an approach dividing the world of philosophy into what he called "non-overlapping magisteria" (NOMA). In this view, questions of the supernatural, such as those relating to the existence and nature of God, are non-empirical and are the proper domain of theology. The methods of science should then be used to answer any empirical question about the natural world, and theology should be used to answer questions about ultimate meaning and moral value. In this view, the perceived lack of any empirical footprint from the magisterium of the supernatural onto natural events makes science the sole player in the natural world.
Name the nineteenth century English atheist?
Answer: Charles Bradlaugh

Question: UCLA professor Richard H. Sander published an article in the November 2004 issue of the Stanford Law Review that questioned the effectiveness of racial preferences in law schools. He noted that, prior to his article, there had been no comprehensive study on the effects of affirmative action. The article presents a study that shows that half of all black law students rank near the bottom of their class after the first year of law school and that black law students are more likely to drop out of law school and to fail the bar exam. The article offers a tentative estimate that the production of new black lawyers in the United States would grow by eight percent if affirmative action programs at all law schools were ended. Less qualified black students would attend less prestigious schools where they would be more closely matched in abilities with their classmates and thus perform relatively better. Sander helped to develop a socioeconomically-based affirmative action plan for the UCLA School of Law after the passage of Proposition 209 in 1996, which prohibited the use of racial preferences by public universities in California. This change occurred after studies showed that the graduation rate of blacks at UCLA was 41%, compared to 73% for whites.
Is there an answer to this question: Which legislative work did not prohibit the use of racial preferences for admissions in the state of California?

Answer: unanswerable

QUES: Notwithstanding these technical and commercial successes on the Macintosh platform, their systems remained fairly expensive, making them less competitive in light of the falling costs of components that made IBM PC compatibles cheaper and accelerated their adoption. In 1989, Jean-Louis Gassee had steadfastly refused to lower the profit margins on Mac computers, then there was a component shortage that rocked the exponentially-expanding PC industry that year, forcing Apple USA head Allan Loren to cut prices which dropped Apple's margins. Microsoft Windows 3.0 was released in May 1990, the first iteration of Windows which had a feature set and performance comparable to the significantly costlier Macintosh. Furthermore, Apple had created too many similar models that confused potential buyers; at one point the product lineup was subdivided into Classic, LC, II, Quadra, Performa, and Centris models, with essentially the same computer being sold under a number of different names.
