Here is a question about this article: In a further refinement of the direct use of probabilistic modelling, statistical estimates can be coupled to an algorithm called arithmetic coding. Arithmetic coding is a more modern coding technique that uses the mathematical calculations of a finite-state machine to produce a string of encoded bits from a series of input data symbols. It can achieve superior compression to other techniques such as the better-known Huffman algorithm. It uses an internal memory state to avoid the need to perform a one-to-one mapping of individual input symbols to distinct representations that use an integer number of bits, and it clears out the internal memory only after encoding the entire string of data symbols. Arithmetic coding applies especially well to adaptive data compression tasks where the statistics vary and are context-dependent, as it can be easily coupled with an adaptive model of the probability distribution of the input data. An early example of the use of arithmetic coding was its use as an optional (but not widely used) feature of the JPEG image coding standard. It has since been applied in various other designs including H.264/MPEG-4 AVC and HEVC for video coding.
What is the answer to this question: What can be paired with an algorithm called arithmetic coding?
****
So... statistical estimates


Here is a question about this article: Political corruption is the use of powers by government officials for illegitimate private gain. An illegal act by an officeholder constitutes political corruption only if the act is directly related to their official duties, is done under color of law or involves trading in influence.
What is the answer to this question: Who benefits from political corruption?

So... government officials


Here is a question about this article: Rep. Christopher H. Smith (R-NJ), criticized the State Department investigation, saying the investigators were shown "Potemkin Villages" where residents had been intimidated into lying about the family-planning program. Dr. Nafis Sadik, former director of UNFPA said her agency had been pivotal in reversing China's coercive population control methods, but a 2005 report by Amnesty International and a separate report by the United States State Department found that coercive techniques were still regularly employed by the Chinese, casting doubt upon Sadik's statements.
What is the answer to this question: Which NGO investigated the Chinese program in 2005?

So...
Amnesty International
