Problem: Northwestern University:

The Latin phrase on Northwestern's seal, Quaecumque sunt vera (Whatsoever things are true) is drawn from the Epistle of Paul to the Philippians 4:8, while the Greek phrase inscribed on the pages of an open book is taken from the Gospel of John 1:14: (The Word full of grace and truth). Purple became Northwestern's official color in 1892, replacing black and gold after a university committee concluded that too many other universities had used these colors. Today, Northwestern's official color is purple, although white is something of an official color as well, being mentioned in both the university's earliest song, Alma Mater (1907) ("Hail to purple, hail to white") and in many university guidelines.

What does the Greek phrase that is inscribed on the pages of an open book on the seal mean?

A: The Word full of grace and truth

Problem: The archipelago has a wet oceanic climate with pleasant temperatures but consistent moderate to heavy rainfall and very limited sunshine, due to the persistent westerly winds. The number of rainy days is comparable to the Aleutian Islands at a much higher latitude in the northern hemisphere, while sunshine hours are comparable to Juneau, Alaska, 20 farther from the equator. Frost is unknown below elevations of 500 metres (1,600 ft) and summer temperatures are similarly mild, never reaching 25 C (77 F). Sandy Point on the east coast is reputed to be the warmest and driest place on the island, being in the lee of the prevailing winds.

Through the 1960s, 1970s, and 1980s, various methods to improve the dynamic range of mass-produced records involved highly advanced disc cutting equipment. These techniques, marketed, to name two, as the CBS DisComputer and Teldec Direct Metal Mastering, were used to reduce inner-groove distortion. RCA Victor introduced another system to reduce dynamic range and achieve a groove with less surface noise under the commercial name of Dynagroove. Two main elements were combined: another disk material with less surface noise in the groove and dynamic compression for masking background noise. Sometimes this was called "diaphragming" the source material and not favoured by some music lovers for its unnatural side effects. Both elements were reflected in the brandname of Dynagroove, described elsewhere in more detail. It also used the earlier advanced method of forward-looking control on groove spacing with respect to volume of sound and position on the disk. Lower recorded volume used closer spacing; higher recorded volume used wider spacing, especially with lower frequencies. Also, the higher track density at lower volumes enabled disk recordings to end farther away from the disk center than usual, helping to reduce endtrack distortion even further.
Who developed the Dynagroove format?
A: RCA Victor

Context and question: Following the success of Le Journal de Mickey (193444), dedicated comics magazines and full-colour comics albums became the primary outlet for comics in the mid-20th century. As in the US, at the time comics were seen as infantile and a threat to culture and literacy; commentators stated that "none bear up to the slightest serious analysis",[c] and that comics were "the sabotage of all art and all literature".[d]
In the United States in the middle of the 20th century comics were seen as a risk to culture and what?
Answer: literacy

Question: Antonio Vivaldi composed a mandolin concerto (Concerto in C major Op.3 6) and two concertos for two mandolins and orchestra. Wolfgang Amadeus Mozart placed it in his 1787 work Don Giovanni and Beethoven created four variations of it. Antonio Maria Bononcini composed La conquista delle Spagne di Scipione Africano il giovane in 1707 and George Frideric Handel composed Alexander Balus in 1748. Others include Giovani Battista Gervasio (Sonata in D major for Mandolin and Basso Continuo), Giuseppe Giuliano (Sonata in D major for Mandolin and Basso Continuo), Emanuele Barbella (Sonata in D major for Mandolin and Basso Continuo), Domenico Scarlatti (Sonata n.54 (K.89) in D minor for Mandolin and Basso Continuo), and Addiego Guerra (Sonata in G major for Mandolin and Basso Continuo).
Is there an answer to this question: What two artists created five variations of the Concerto in D Major Op 3 6?

The common features of passive solar architecture are orientation relative to the Sun, compact proportion (a low surface area to volume ratio), selective shading (overhangs) and thermal mass. When these features are tailored to the local climate and environment they can produce well-lit spaces that stay in a comfortable temperature range. Socrates' Megaron House is a classic example of passive solar design. The most recent approaches to solar design use computer modeling tying together solar lighting, heating and ventilation systems in an integrated solar design package. Active solar equipment such as pumps, fans and switchable windows can complement passive design and improve system performance.
What is produced when the features of passive solar architecture are customized to the environment?
A:
well-lit spaces that stay in a comfortable temperature range
