Problem: Green:

In additive color devices such as computer displays and televisions, one of the primary light sources is typically a narrow-spectrum yellowish-green of dominant wavelength ~550 nm; this "green" primary is combined with an orangish-red "red" primary and a purplish-blue "blue" primary to produce any color in between – the RGB color model. A unique green (green appearing neither yellowish nor bluish) is produced on such a device by mixing light from the green primary with some light from the blue primary.

~550nm green is a combination of which two primary colours?

Problem: The 1916 Zoning Resolution required setbacks in new buildings, and restricted towers to a percentage of the lot size, to allow sunlight to reach the streets below. The Art Deco style of the Chrysler Building (1930) and Empire State Building (1931), with their tapered tops and steel spires, reflected the zoning requirements. The buildings have distinctive ornamentation, such as the eagles at the corners of the 61st floor on the Chrysler Building, and are considered some of the finest examples of the Art Deco style. A highly influential example of the international style in the United States is the Seagram Building (1957), distinctive for its façade using visible bronze-toned I-beams to evoke the building's structure. The Condé Nast Building (2000) is a prominent example of green design in American skyscrapers and has received an award from the American Institute of Architects as well as AIA New York State for its design.
Which animal decorates the corners of the Chrysler Building?

Answer: eagles

To Secure These Rights also called for desegregation of the Armed Forces. "Prejudice in any area is an ugly, undemocratic phenomenon, but in the armed services, where all men run the risk of death, it is especially repugnant." The rationale was fairness: "When an individual enters the service of the country, he necessarily surrenders some of the rights and privileges which are inherent in American citizenship." In return, the government "undertakes to protect his integrity as an individual." Yet that was not possible in the segregated Army, since "any discrimination which…prevents members of the minority groups from rendering full military service in defense of their country is for them a humiliating badge of inferiority." The report called for an end to "all discrimination and segregation based on race, color, creed, or national origins in…all branches of the Armed Services.":38–39
Discrimination that prevented minorities from serving their country to the best of their abilities was seen as what?
A: a humiliating badge of inferiority


Context and question: To the south, the Sahara is bounded by the Sahel, a belt of dry tropical savanna with a summer rainy season that extends across Africa from east to west. The southern limit of the Sahara is indicated botanically by the southern limit of Cornulaca monacantha (a drought-tolerant member of the Chenopodiaceae), or northern limit of Cenchrus biflorus, a grass typical of the Sahel. According to climatic criteria, the southern limit of the Sahara corresponds to the 150 mm (5.9 in) isohyet of annual precipitation (this is a long-term average, since precipitation varies annually).
What type of Savanah is north and south of the Sahara
Answer: unanswerable


Question: The government, consisting of the monarch and the ministers, will then usually approve the proposal and the sovereign and one of the ministers signs the proposal with the addition of an enacting clause, thereafter notifying the States General that "The King assents to the proposal." It has happened in exceptional circumstances that the government does not approve a law that has been passed in parliament. In such a case, neither the monarch nor a minister will sign the bill, notifying the States General that "The King will keep the proposal under advisement." A law that has received royal assent will be published in the State Magazine, with the original being kept in the archives of the King's Offices.
Is there an answer to this question: A law that has not received royal assent will be published where?

Answer: unanswerable

Isolated remains of Homo erectus in Hathnora in the Narmada Valley in central India indicate that India might have been inhabited since at least the Middle Pleistocene era, somewhere between 500,000 and 200,000 years ago. Tools crafted by proto-humans that have been dated back two million years have been discovered in the northwestern part of the subcontinent. The ancient history of the region includes some of South Asia's oldest settlements and some of its major civilisations. The earliest archaeological site in the subcontinent is the palaeolithic hominid site in the Soan River valley. Soanian sites are found in the Sivalik region across what are now India, Pakistan, and Nepal.
What type of resident lived at the site in Soan River Valley?
A:
palaeolithic hominid
