Problem: In the late 14th century, in the Grand Duchy of Lithuania, Vytautas the Great reformed the Grand Duchy's army: instead of calling all men to arms, he created forces comprising professional warriors—bajorai ("nobles"; see the cognate "boyar"). As there were not enough nobles, Vytautas trained suitable men, relieving them of labor on the land and of other duties; for their military service to the Grand Duke, they were granted land that was worked by hired men (veldams). The newly formed noble families generally took up, as their family names, the Lithuanian pagan given names of their ennobled ancestors; this was the case with the Goštautai, Radvilos, Astikai, Kęsgailos and others. These families were granted their coats of arms under the Union of Horodlo (1413).
Who gave the coat of arms to others?
The answer is the following: Union of Horodlo

Problem: Parallel with the growth of specialized agencies for conducting or supporting statescraft in the second half of the 20th century has been the collection of resources for scholarship and research typically in university settings. Most universities teaching the liberal arts have library and museum collections. These are not new; however, the erection of these into "centres" of national and international interest in the second half of the 20th century have created larger databases not available to the scholars of the past. Many of these focus on the Ancient Near East or Near East in the sense of Ancient Near East.
What has had parallel growth of in the 20th century?
The answer is the following: the collection of resources

Problem: A text is self-referential when it speaks about itself and makes reference to itself. According to Stefan Wild, the Quran demonstrates this metatextuality by explaining, classifying, interpreting and justifying the words to be transmitted. Self-referentiality is evident in those passages where the Quran refers to itself as revelation (tanzil), remembrance (dhikr), news (naba'), criterion (furqan) in a self-designating manner (explicitly asserting its Divinity, "And this is a blessed Remembrance that We have sent down; so are you now denying it?"), or in the frequent appearance of the "Say" tags, when Muhammad is commanded to speak (e.g., "Say: 'God's guidance is the true guidance' ", "Say: 'Would you then dispute with us concerning God?' "). According to Wild the Quran is highly self-referential. The feature is more evident in early Meccan suras.
The Quran is more self-referential in which of its suras?
The answer is the following: early Meccan suras

Problem: Biodiversity's relevance to human health is becoming an international political issue, as scientific evidence builds on the global health implications of biodiversity loss. This issue is closely linked with the issue of climate change, as many of the anticipated health risks of climate change are associated with changes in biodiversity (e.g. changes in populations and distribution of disease vectors, scarcity of fresh water, impacts on agricultural biodiversity and food resources etc.) This is because the species most likely to disappear are those that buffer against infectious disease transmission, while surviving species tend to be the ones that increase disease transmission, such as that of West Nile Virus, Lyme disease and Hantavirus, according to a study done co-authored by Felicia Keesing, an ecologist at Bard College, and Drew Harvell, associate director for Environment of the Atkinson Center for a Sustainable Future (ACSF) at Cornell University.
What issue is closely linked with changes in biodiversity?
The answer is the following:
climate change
