Problem: Data compression:

Data compression can be viewed as a special case of data differencing: Data differencing consists of producing a difference given a source and a target, with patching producing a target given a source and a difference, while data compression consists of producing a compressed file given a target, and decompression consists of producing a target given only a compressed file. Thus, one can consider data compression as data differencing with empty source data, the compressed file corresponding to a "difference from nothing." This is the same as considering absolute entropy (corresponding to data compression) as a special case of relative entropy (corresponding to data differencing) with no initial data.

What is made up of producing a compressed file given a source and a target?
---
A: unanswerable

Problem: Muammar Gaddafi:

The RCC attempted to suppress regional and tribal affiliation, replacing it with a unified pan-Libyan identity. In doing so, they tried discrediting tribal leaders as agents of the old regime, and in August 1971 a Sabha military court tried many of them for counter-revolutionary activity. Long-standing administrative boundaries were re-drawn, crossing tribal boundaries, while pro-revolutionary modernizers replaced traditional leaders, but the communities they served often rejected them. Realizing the failures of the modernizers, Gaddafi created the Arab Socialist Union (ASU), a mass mobilization vanguard party of which he was president. The ASU recognized the RCC as its "Supreme Leading Authority", and was designed to further revolutionary enthusiasm throughout the country.

What were tribal leaders accused of in 1971?
---
A:
counter-revolutionary activity
