Question: Two major extant branches of Buddhism are generally recognized by scholars: Theravada ("The School of the Elders") and Mahayana ("The Great Vehicle"). Vajrayana, a body of teachings attributed to Indian siddhas, may be viewed as a third branch or merely a part of Mahayana. Theravada has a widespread following in Sri Lanka and Southeast Asia. Mahayana which includes the traditions of Pure Land, Zen, Nichiren Buddhism, Shingon, and Tiantai (Tendai) is found throughout East Asia. Tibetan Buddhism, which preserves the Vajrayana teachings of eighth century India, is practiced in regions surrounding the Himalayas, Mongolia and Kalmykia. Buddhists number between an estimated 488 million[web 1] and 535 million, making it one of the world's major religions.
Is there an answer to this question: Vajrayana is attributed to who?

Answer: Indian siddhas


Question: The United Nations formulates multiple regional divisions as is convenient for its various operations. But few of them include a Near East, and that poorly defined. UNICEF recognizes the "Middle East and North Africa" region, where the Middle East is bounded by the Red Sea on the west and includes Iran on the east. UNESCO recognizes neither a Near East nor a Middle East, dividing the countries instead among three regions: Arab States, Asia and the Pacific, and Africa. Its division "does not forcibly reflect geography" but "refers to the execution of regional activities." The United Nations Statistics Division defines Western Asia to contain the countries included elsewhere in the Middle East. The Food and Agriculture Organization (FAO) describes its entire theatre of operations as the Near East, but then assigns many of its members to other regions as well; for example, Cyprus, Malta and Turkey are in both the European and the Near Eastern regions. Its total area extends further into Central Asia than that of most agencies.
Is there an answer to this question: Who recognizes the "Middle East and North Africa" region?

Answer: UNICEF


Question: One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights or lanterns (chromacity and luminance standards being set under the Convention on the International Regulations for Preventing Collisions at Sea 1972, Annex I and the CIE) and LED-based Christmas lights. In cold climates, LED traffic lights may remain snow-covered. Red or yellow LEDs are used in indicator and alphanumeric displays in environments where night vision must be retained: aircraft cockpits, submarine and ship bridges, astronomy observatories, and in the field, e.g. night time animal watching and military field use.
Is there an answer to this question:  In what year were non-luminescence standards set?

Answer: unanswerable


Question: In the early 1980s, a small but vocal segment of anthropologists and archaeologists attempted to demonstrate that contemporary groups usually identified as hunter-gatherers do not, in most cases, have a continuous history of hunting and gathering, and that in many cases their ancestors were agriculturalists and/or pastoralists[citation needed] who were pushed into marginal areas as a result of migrations, economic exploitation, and/or violent conflict (see, for example, the Kalahari Debate). The result of their effort has been the general acknowledgement that there has been complex interaction between hunter-gatherers and non-hunter-gatherers for millennia.[citation needed]
Is there an answer to this question: Ho wlong has there been simple interaction between hunter-gatherers and non-hunter-gatherers?

Answer:
unanswerable
