Problem: Sino-Tibetan relations during the Ming dynasty:

Wang and Nyima state that after the official title "Education Minister" was granted to Tai Situ Changchub Gyaltsen (13021364) by the Yuan court, this title appeared frequently with his name in various Tibetan texts, while his Tibetan title "Degsi" (sic properly sde-srid or desi) is seldom mentioned. Wang and Nyima take this to mean that "even in the later period of the Yuan dynasty, the Yuan imperial court and the Phagmodrupa Dynasty maintained a Central-local government relation." The Tai Situpa is even supposed to have written in his will: "In the past I received loving care from the emperor in the east. If the emperor continues to care for us, please follow his edicts and the imperial envoy should be well received."

What title was given by the Yuan court to Tai Situ Changchub Gyaltsen ?
---
A: Education Minister

Problem: Somalis:

Irir Samaale, the oldest common ancestor of several Somali clans, is generally regarded as the source of the ethnonym Somali. The name "Somali" is, in turn, held to be derived from the words soo and maal, which together mean "go and milk" a reference to the ubiquitous pastoralism of the Somali people. Another plausible etymology proposes that the term Somali is derived from the Arabic for "wealthy" (dhawamaal), again referring to Somali riches in livestock.

What resource traditionally comprised Somali wealth?
---
A: livestock

Problem: BeiDou Navigation Satellite System:

Frequencies for COMPASS are allocated in four bands: E1, E2, E5B, and E6 and overlap with Galileo. The fact of overlapping could be convenient from the point of view of the receiver design, but on the other hand raises the issues of inter-system interference, especially within E1 and E2 bands, which are allocated for Galileo's publicly regulated service. However, under International Telecommunication Union (ITU) policies, the first nation to start broadcasting in a specific frequency will have priority to that frequency, and any subsequent users will be required to obtain permission prior to using that frequency, and otherwise ensure that their broadcasts do not interfere with the original nation's broadcasts. It now appears that Chinese COMPASS satellites will start transmitting in the E1, E2, E5B, and E6 bands before Europe's Galileo satellites and thus have primary rights to these frequency ranges.

Which bands are used by the Galileo system for their public service?
---
A: E1 and E2

Problem: Queen Victoria:

Victoria's youngest son, Leopold, was affected by the blood-clotting disease haemophilia B and two of her five daughters, Alice and Beatrice, were carriers. Royal haemophiliacs descended from Victoria included her great-grandsons, Tsarevich Alexei of Russia, Alfonso, Prince of Asturias, and Infante Gonzalo of Spain. The presence of the disease in Victoria's descendants, but not in her ancestors, led to modern speculation that her true father was not the Duke of Kent but a haemophiliac. There is no documentary evidence of a haemophiliac in connection with Victoria's mother, and as male carriers always suffer the disease, even if such a man had existed he would have been seriously ill. It is more likely that the mutation arose spontaneously because Victoria's father was over 50 at the time of her conception and haemophilia arises more frequently in the children of older fathers. Spontaneous mutations account for about a third of cases.

What is the sex of carriers that always suffer the blood clotting disease haemophi;ia B?
---
A:
male
