Problem: Sino-Tibetan relations during the Ming dynasty:

Rawski writes that Altan Khan's conversion to the Gelug "can be interpreted as an attempt to expand his authority in his conflict with his nominal superior, Tümen Khan." To further cement the Mongol-Tibetan alliance, the great-grandson of Altan Khan—the 4th Dalai Lama (1589–1616)—was made the fourth Dalai Lama. In 1642, the 5th Dalai Lama (1617–1682) became the first to wield effective political control over Tibet.

To make the Mongol-Tibetan alliance stronger who became the 4th Dalai Lama?
---
A: the great-grandson of Altan Khan


Problem: Eritrea is a multilingual country. The nation has no official language, as the Constitution establishes the "equality of all Eritrean languages". However, Tigrinya serves as the de facto language of national identity. With 2,540,000 total speakers of a population of 5,254,000 in 2006, Tigrinya is the most widely spoken language, particularly in the southern and central parts of Eritrea. Modern Standard Arabic and English serve as de facto working languages, with the latter used in university education and many technical fields. Italian, the former colonial language, is widely used in commerce and is taught as a second language in schools, with a few elderly monolinguals.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
International friendlies give team managers the opportunity to experiment with team selection and tactics before the tournament proper, and also allow them to assess the abilities of players they may potentially select for the tournament squad. Players can be booked in international friendlies, and can be suspended from future international matches based on red cards or accumulated yellows in a specified period. Caps and goals scored also count towards a player's career records. In 2004, FIFA ruled that substitutions by a team be limited to six per match in international friendlies, in response to criticism that such matches were becoming increasingly farcical with managers making as many as 11 substitutions per match.
What color cards determine whether players can participate in league games?
A: unanswerable


Context and question: The term Nederduits, however introduced new confusion, since the non standardised dialects spoken in the north of Germany came to be known as Niederdeutsch as well, and thus the Duits reference in the name was dropped, leading to Nederlands as designation to refer to the Dutch language. The repeated use of Neder (or "low") to refer to the Dutch language is a reference to the Netherlands' downriver location at the Rhine–Meuse–Scheldt delta near the North Sea, harking back to Latin nomenclature, e.g. Germania Inferior. See also: Netherlands (toponymy).
The Netherlands are "low" because of their placement near what delta by the North Sea?
Answer: Rhine–Meuse–Scheldt delta


Question: There are two levels of service provided — a free service to civilians and licensed service to the Chinese government and military. The free civilian service has a 10-meter location-tracking accuracy, synchronizes clocks with an accuracy of 10 nanoseconds, and measures speeds to within 0.2 m/s. The restricted military service has a location accuracy of 10 centimetres, can be used for communication, and will supply information about the system status to the user. To date, the military service has been granted only to the People's Liberation Army and to the Military of Pakistan.
Is there an answer to this question: What types of services will be offered by the BeiDou system?

Answer: a free service to civilians and licensed service to the Chinese government and military


QUES: Incubation, which optimises temperature for chick development, usually begins after the last egg has been laid. In monogamous species incubation duties are often shared, whereas in polygamous species one parent is wholly responsible for incubation. Warmth from parents passes to the eggs through brood patches, areas of bare skin on the abdomen or breast of the incubating birds. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as 83 grams (2.9 oz) of body weight per day of incubation. The warmth for the incubation of the eggs of megapodes comes from the sun, decaying vegetation or volcanic sources. Incubation periods range from 10 days (in woodpeckers, cuckoos and passerine birds) to over 80 days (in albatrosses and kiwis).

When does incubation begin?
What is the answer?
ANS:
after the last egg has been laid
