Problem: Religion in ancient Rome:

Romulus was credited with several religious institutions. He founded the Consualia festival, inviting the neighbouring Sabines to participate; the ensuing rape of the Sabine women by Romulus's men further embedded both violence and cultural assimilation in Rome's myth of origins. As a successful general, Romulus is also supposed to have founded Rome's first temple to Jupiter Feretrius and offered the spolia opima, the prime spoils taken in war, in the celebration of the first Roman triumph. Spared a mortal's death, Romulus was mysteriously spirited away and deified.

What religious festival did Romulus found?

A: Consualia

Problem: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.
What can improve the efficiency of LED-based white light?

Answer: more efficient phosphors

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The old oracles in Delphi seem to be connected with a local tradition of the priesthood, and there is not clear evidence that a kind of inspiration-prophecy existed in the temple. This led some scholars to the conclusion that Pythia carried on the rituals in a consistent procedure through many centuries, according to the local tradition. In that regard, the mythical seeress Sibyl of Anatolian origin, with her ecstatic art, looks unrelated to the oracle itself. However, the Greek tradition is referring to the existence of vapours and chewing of laurel-leaves, which seem to be confirmed by recent studies.
What Greek tradition seems to be confirmed by recent studies?
A: existence of vapours and chewing of laurel-leaves

Context and question: Islam is the most widely practised religion in Southeast Asia, numbering approximately 240 million adherents which translate to about 40% of the entire population, with majorities in Indonesia, Brunei, Malaysia and in Southern Philippines with Indonesia as the largest and most populated Muslim country around the world. Countries in Southeast Asia practice many different religions. Buddhism is predominant in Thailand, Cambodia, Laos, Burma, Vietnam and Singapore. Ancestor worship and Confucianism are also widely practised in Vietnam and Singapore. Christianity is predominant in the Philippines, eastern Indonesia, East Malaysia and East Timor. The Philippines has the largest Roman Catholic population in Asia. East Timor is also predominantly Roman Catholic due to a history of Portuguese rule.
What is the least practiced religion in Southeast Asia?
Answer: unanswerable

Question: As in the Scheiner system, speeds were expressed in 'degrees'. Originally the sensitivity was written as a fraction with 'tenths' (for example "18/10 DIN"), where the resultant value 1.8 represented the relative base 10 logarithm of the speed. 'Tenths' were later abandoned with DIN 4512:1957-11, and the example above would be written as "18 DIN". The degree symbol was finally dropped with DIN 4512:1961-10. This revision also saw significant changes in the definition of film speeds in order to accommodate then-recent changes in the American ASA PH2.5-1960 standard, so that film speeds of black-and-white negative film effectively would become doubled, that is, a film previously marked as "18 DIN" would now be labeled as "21 DIN" without emulsion changes.
Is there an answer to this question: Why did the definition of film speeds change considerably?

Answer: to accommodate then-recent changes in the American ASA PH2.5-1960 standard

QUES: The northern group consists of the keskmurre or central dialect that is also the basis for the standard language, the laanemurre or western dialect, roughly corresponding to Laanemaa and Parnumaa, the saarte murre (islands') dialect of Saaremaa and Hiiumaa and the idamurre or eastern dialect on the northwestern shore of Lake Peipsi.

What is the dialect from Lake Peipsi?
What is the answer?
ANS:
