Input: Read this: Layer III audio can also use a "bit reservoir", a partially full frame's ability to hold part of the next frame's audio data, allowing temporary changes in effective bitrate, even in a constant bitrate stream. Internal handling of the bit reservoir increases encoding delay.[citation needed]
Question: What kind of audio is required to use a bit reservoir?

Output: Layer III

Input: Read this: 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.

Many Tajiks left the education system due to low demand in the labor market for people with extensive educational training or professional skills.
Question: There is a small number of tertiary education what?

Output: unanswerable

Input: Read this: It also includes the alternative 14401152 HDMAC scan format.

Question: What was viewed by some as enhanced television format and not true HDTV format?

Output:
a mooted 750-line
