Problem: Please answer a question about the following article about MP3:
The simplest type of MP3 file uses one bit rate for the entire file: this is known as Constant Bit Rate (CBR) encoding. Using a constant bit rate makes encoding simpler and faster. However, it is also possible to create files where the bit rate changes throughout the file. These are known as Variable Bit Rate (VBR) files. The idea behind this is that, in any piece of audio, some parts will be much easier to compress, such as silence or music containing only a few instruments, while others will be more difficult to compress. So, the overall quality of the file may be increased by using a lower bit rate for the less complex passages and a higher one for the more complex parts. With some encoders, it is possible to specify a given quality, and the encoder will vary the bit rate accordingly. Users who know a particular "quality setting" that is transparent to their ears can use this value when encoding all of their music, and generally speaking not need to worry about performing personal listening tests on each piece of music to determine the correct bit rate.
What does CBR stand for?
A: Constant Bit Rate
Problem: Please answer a question about the following article about Wood:
The general effect of the water content upon the wood substance is to render it softer and more pliable. A similar effect of common observation is in the softening action of water on rawhide, paper, or cloth. Within certain limits, the greater the water content, the greater its softening effect.
What type of action does water create in cloth?
A: softening
Problem: Please answer a question about the following article about Frederic Chopin:
Works published since 1857 have received alternative catalogue designations instead of opus numbers. The present standard musicological reference for Chopin's works is the Kobylanska Catalogue (usually represented by the initials 'KK'), named for its compiler, the Polish musicologist Krystyna Kobylanska.
What is the shortened reference for the Kobylanska Catalogue?
A: KK
Problem: Please answer a question about the following article about East India Company:
With the gradual weakening of the Marathas in the aftermath of the three Anglo-Maratha wars, the British also secured the Ganges-Jumna Doab, the Delhi-Agra region, parts of Bundelkhand, Broach, some districts of Gujarat, the fort of Ahmmadnagar, province of Cuttack (which included Mughalbandi/the coastal part of Odisha, Garjat/the princely states of Odisha, Balasore Port, parts of Midnapore district of West Bengal), Bombay (Mumbai) and the surrounding areas, leading to a formal end of the Maratha empire and firm establishment of the British East India Company in India.
With the formal end of Maratha Empire the EIC created a firm hold on what country?
A:
India
