Problem: Asphalt:

The expression "bitumen" originated in the Sanskrit, where we find the words jatu, meaning "pitch," and jatu-krit, meaning "pitch creating", "pitch producing" (referring to coniferous or resinous trees). The Latin equivalent is claimed by some to be originally gwitu-men (pertaining to pitch), and by others, pixtumens (exuding or bubbling pitch), which was subsequently shortened to bitumen, thence passing via French into English. From the same root is derived the Anglo Saxon word cwidu (mastix), the German word Kitt (cement or mastic) and the old Norse word kvada.

What does the German word cwidu mean?

A: unanswerable

In Lemon v. Kurtzman, 403 U.S. 602 (1971), the court determined that a Pennsylvania state policy of reimbursing the salaries and related costs of teachers of secular subjects in private religious schools violated the Establishment Clause. The court's decision argued that the separation of church and state could never be absolute: "Our prior holdings do not call for total separation between church and state; total separation is not possible in an absolute sense. Some relationship between government and religious organizations is inevitable," the court wrote. "Judicial caveats against entanglement must recognize that the line of separation, far from being a "wall," is a blurred, indistinct, and variable barrier depending on all the circumstances of a particular relationship."
What did the state's policy violate?
A: the Establishment Clause


Context and question: Color temperature for white light sources also affects their use for certain applications. The color temperature of a white light source is the temperature in Kelvin of a theoretical black body emitter that most closely matches the spectral characteristics of the lamp. An incandescent bulb has a color temperature around 2800 to 3000 Kelvin; daylight is around 6400 Kelvin. Lower color temperature lamps have relatively more energy in the yellow and red part of the visible spectrum, while high color temperatures correspond to lamps with more of a blue-white appearance. For critical inspection or color matching tasks, or for retail displays of food and clothing, the color temperature of the lamps will be selected for the best overall lighting effect.
A lamp with more energy in the yellow and red spectrum are known to be?
Answer: Lower color temperature


Question: In 1840, Louis Philippe I obtained permission from the British to return Napoleon's remains to France. On 15 December 1840, a state funeral was held. The hearse proceeded from the Arc de Triomphe down the Champs-Élysées, across the Place de la Concorde to the Esplanade des Invalides and then to the cupola in St Jérôme's Chapel, where it remained until the tomb designed by Louis Visconti was completed. In 1861, Napoleon's remains were entombed in a porphyry sarcophagus in the crypt under the dome at Les Invalides.
Is there an answer to this question:  In what building was the cupola where Napoleon's remains were first placed located?

Answer: St Jérôme's Chapel

The evolution of Proto-Greek should be considered within the context of an early Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages. The characteristically Greek representation of word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language, which also seems to share some other phonological and morphological peculiarities of Greek; this has led some linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.
 What other things do the three languages seem to have in common ?
A:
unanswerable
