Problem: Gramophone record:

There is a theory that vinyl records can audibly represent higher frequencies than compact discs. According to Red Book specifications, the compact disc has a frequency response of 20 Hz up to 22,050 Hz, and most CD players measure flat within a fraction of a decibel from at least 20 Hz to 20 kHz at full output. Turntable rumble obscures the low-end limit of vinyl but the upper end can be, with some cartridges, reasonably flat within a few decibels to 30 kHz, with gentle roll-off. Carrier signals of Quad LPs popular in the 1970s were at 30 kHz to be out of the range of human hearing. The average human auditory system is sensitive to frequencies from 20 Hz to a maximum of around 20,000 Hz. The upper and lower frequency limits of human hearing vary per person.

What is generally the lowest sound a human can hear?
---
A: 20 Hz


Problem: Washington University has over 300 undergraduate student organizations on campus. Most are funded by the Washington University Student Union, which has a $2 million plus annual budget that is completely student-controlled and is one of the largest student government budgets in the country. Known as SU for short, the Student Union sponsors large-scale campus programs including WILD (a semesterly concert in the quad) and free copies of the New York Times, USA Today, and the St. Louis Post-Dispatch through The Collegiate Readership Program; it also contributes to the Assembly Series, a weekly lecture series produced by the University, and funds the campus television station, WUTV, and the radio station, KWUR. KWUR was named best radio station in St. Louis of 2003 by the Riverfront Times despite the fact that its signal reaches only a few blocks beyond the boundaries of the campus. There are 11 fraternities and 9 sororities, with approximately 35% of the student body being involved in Greek life. The Congress of the South 40 (CS40) is a Residential Life and Events Programming Board, which operates outside of the SU sphere. CS40's funding comes from the Housing Activities Fee of each student living on the South 40.
How many weekly lecture series are there on the Washington University campus each year?

Context and question: J. Brent Walker, Executive Director of the Baptist Joint Committee, responded to Hamburger's claims noting; "The fact that the separation of church and state has been supported by some who exhibited an anti-Catholic animus or a secularist bent does not impugn the validity of the principle. Champions of religious liberty have argued for the separation of church and state for reasons having nothing to do with anti-Catholicism or desire for a secular culture. Of course, separationists have opposed the Catholic Church when it has sought to tap into the public till to support its parochial schools or to argue for on-campus released time in the public schools. But that principled debate on the issues does not support a charge of religious bigotry"
 Who have argued for the separation of church and state for reasons having everything to do with a desire for a secular culture?
Answer: unanswerable


Question: Dell was the first company to publicly state a timeline for the elimination of toxic polyvinyl chloride (PVC) and brominated flame retardants (BFRs), which it planned to phase out by the end of 2009. It revised this commitment and now aims to remove these toxics by the end of 2011 but only in its computing products. In March 2010, Greenpeace activists protested at Dell offices in Bangalore, Amsterdam and Copenhagen calling for Dell’s founder and CEO Michael Dell to ‘drop the toxics’ and claiming that Dell’s aspiration to be ‘the greenest technology company on the planet’ was ‘hypocritical’. Dell has launched its first products completely free of PVC and BFRs with the G-Series monitors (G2210 and G2410) in 2009.
Is there an answer to this question: By what year does Dell plan to remove chemicals from its computers?

Answer: 2011


John remained Lord of Ireland throughout his reign. He drew on the country for resources to fight his war with Philip on the continent. Conflict continued in Ireland between the Anglo-Norman settlers and the indigenous Irish chieftains, with John manipulating both groups to expand his wealth and power in the country. During Richard's rule, John had successfully increased the size of his lands in Ireland, and he continued this policy as king. In 1210 the king crossed into Ireland with a large army to crush a rebellion by the Anglo-Norman lords; he reasserted his control of the country and used a new charter to order compliance with English laws and customs in Ireland. John stopped short of trying to actively enforce this charter on the native Irish kingdoms, but historian David Carpenter suspects that he might have done so, had the baronial conflict in England not intervened. Simmering tensions remained with the native Irish leaders even after John left for England.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): John remained what throughout his reign?
Ah, so..
Lord of Ireland
