QUES: Public education in Tajikistan consists of 11 years of primary and secondary education but the government has plans to implement a 12-year system in 2016. There is a relatively large number of tertiary education institutions including Khujand State University which has 76 departments in 15 faculties, Tajikistan State University of Law, Business, & Politics, Khorugh State University, Agricultural University of Tajikistan, Tajik State National University, and several other institutions. Most, but not all, universities were established during the Soviet Era. As of 2008[update] tertiary education enrollment was 17%, significantly below the sub-regional average of 37%. Many Tajiks left the education system due to low demand in the labor market for people with extensive educational training or professional skills.

What is the answer?
ANS: 17%

Instruments like the duduk, the dhol, the zurna and the kanun are commonly found in Armenian folk music. Artists such as Sayat Nova are famous due to their influence in the development of Armenian folk music. One of the oldest types of Armenian music is the Armenian chant which is the most common kind of religious music in Armenia. Many of these chants are ancient in origin, extending to pre-Christian times, while others are relatively modern, including several composed by Saint Mesrop Mashtots, the inventor of the Armenian alphabet.

Question: Things were looking grim for Prussia now, with the Austrians mobilising to attack Prussian-controlled soil and a French army under Soubise approaching from the west. However, in November and December of 1757, the whole situation in Germany was reversed. First, Frederick devastated Prince Soubise's French force at the Battle of Rossbach on 5 November 1757 and then routed a vastly superior Austrian force at the Battle of Leuthen on 5 December 1757 With these victories, Frederick once again established himself as Europe's premier general and his men as Europe's most accomplished soldiers. In spite of this, the Prussians were now facing the prospect of four major powers attacking on four fronts (France from the West, Austria from the South, Russia from the East and Sweden from the North). Meanwhile, a combined force from a number of smaller German states such as Bavaria had been established under Austrian leadership, thus threatening Prussian control of Saxony.
Try to answer this question if possible: What were reasons that the late 1757 time frame looked bad for Prussia?
Answer: the Austrians mobilising to attack Prussian-controlled soil and a French army under Soubise approaching from the west
