Problem: Tibet:

Between 1346 and 1354, Tai Situ Changchub Gyaltsen toppled the Sakya and founded the Phagmodrupa Dynasty. The following 80 years saw the founding of the Gelug school (also known as Yellow Hats) by the disciples of Je Tsongkhapa, and the founding of the important Ganden, Drepung and Sera monasteries near Lhasa. However, internal strife within the dynasty and the strong localism of the various fiefs and political-religious factions led to a long series of internal conflicts. The minister family Rinpungpa, based in Tsang (West Central Tibet), dominated politics after 1435. In 1565 they were overthrown by the Tsangpa Dynasty of Shigatse which expanded its power in different directions of Tibet in the following decades and favoured the Karma Kagyu sect.

Who dominated politics after 1435?

A: minister family Rinpungpa


Problem: For digital photo cameras ("digital still cameras"), an exposure index (EI) rating—commonly called ISO setting—is specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the camera's parameters for interpreting the sensor data values into sRGB values are fixed, and a number of different EI choices are accommodated by varying the sensor's signal gain in the analog realm, prior to conversion to digital. Some camera designs provide at least some EI choices by adjusting the sensor's signal gain in the digital realm. A few camera designs also provide EI adjustment through a choice of lightness parameters for the interpretation of sensor data values into sRGB; this variation allows different tradeoffs between the range of highlights that can be captured and the amount of noise introduced into the shadow areas of the photo.
Who provides the exposure index rating?

Answer: the manufacturer

Israeli cuisine has adopted, and continues to adapt, elements of various styles of Jewish cuisine, particularly the Mizrahi, Sephardic, and Ashkenazi styles of cooking, along with Moroccan Jewish, Iraqi Jewish, Ethiopian Jewish, Indian Jewish, Iranian Jewish and Yemeni Jewish influences. It incorporates many foods traditionally eaten in the Arab, Middle Eastern and Mediterranean cuisines, such as falafel, hummus, shakshouka, couscous, and za'atar, which have become common ingredients in Israeli cuisine. Schnitzel, pizza, hamburgers, French fries, rice and salad are also very common in Israel.[citation needed]
What common ingredients are in Israeli cuisine?

Context and question: The BeiDou Navigation Satellite System (BDS, simplified Chinese: 北斗卫星导航系统; traditional Chinese: 北斗衛星導航系統; pinyin: Běidǒu wèixīng dǎoháng xìtǒng) is a Chinese satellite navigation system. It consists of two separate satellite constellations – a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction.
How is the BeiDou Navigation Satellite System written in traditional Chinese?
Answer: 北斗衛星導航系統


Question: More than half of the Jews live in the Diaspora (see Population table). Currently, the largest Jewish community outside Israel, and either the largest or second-largest Jewish community in the world, is located in the United States, with 5.2 million to 6.4 million Jews by various estimates. Elsewhere in the Americas, there are also large Jewish populations in Canada (315,000), Argentina (180,000-300,000), and Brazil (196,000-600,000), and smaller populations in Mexico, Uruguay, Venezuela, Chile, Colombia and several other countries (see History of the Jews in Latin America). Demographers disagree on whether the United States has a larger Jewish population than Israel, with many maintaining that Israel surpassed the United States in Jewish population during the 2000s, while others maintain that the United States still has the largest Jewish population in the world. Currently, a major national Jewish population survey is planned to ascertain whether or not Israel has overtaken the United States in Jewish population.
Is there an answer to this question: What do demographers agree on?

Answer: unanswerable


QUES: The lyrics of the modern Japanese national anthem, Kimi ga Yo, were written in the Heian period, as was The Tale of Genji by Murasaki Shikibu, one of the first novels ever written. Murasaki Shikibu's contemporary and rival Sei Shōnagon's revealing observations and musings as an attendant in the Empress' court were recorded collectively as The Pillow Book in the 990s, which revealed the quotidian capital lifestyle. The Heian period produced a flowering of poetry including works of Ariwara no Narihira, Ono no Komachi, Izumi Shikibu, Murasaki Shikibu, Saigyō and Fujiwara no Teika. The famous Japanese poem known as the Iroha (いろは), of uncertain authorship, was also written during the Heian period.

What famous poem with an unknown author was written during the Heian period?
What is the answer?
ANS:
Iroha
