After Nasser died in November 1970, his successor, Anwar Sadat, suggested that rather than a unified state, they create a political federation, implemented in April 1971; in doing so, Egypt, Syria and Sudan got large grants of Libyan oil money. In February 1972, Gaddafi and Sadat signed an unofficial charter of merger, but it was never implemented as relations broke down the following year. Sadat became increasingly wary of Libya's radical direction, and the September 1973 deadline for implementing the Federation passed by with no action taken.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Along with Libya, what nations joined the political federation?
Ah, so.. Egypt, Syria and Sudan

Compression is useful because it helps reduce resource usage, such as data storage space or transmission capacity. Because compressed data must be decompressed to use, this extra processing imposes computational or other costs through decompression; this situation is far from being a free lunch. Data compression is subject to a spacetime complexity trade-off. For instance, a compression scheme for video may require expensive hardware for the video to be decompressed fast enough to be viewed as it is being decompressed, and the option to decompress the video in full before watching it may be inconvenient or require additional storage. The design of data compression schemes involves trade-offs among various factors, including the degree of compression, the amount of distortion introduced (when using lossy data compression), and the computational resources required to compress and decompress the data.

Ah, so.. unanswerable

Hunter-gathering lifestyles remained prevalent in some parts of the New World, Sub-Saharan Africa, and Siberia, as well as all of Australia, until the European Age of Discovery. They still persist in some tribal societies, albeit in rapid decline. Peoples that preserved paleolithic hunting-gathering until the recent past include some indigenous peoples of the Amazonas (Ache), some Central and Southern African (San people), some peoples of New Guinea (Fayu), the Mlabri of Thailand and Laos, the Vedda people of Sri Lanka, and a handful of uncontacted peoples. In Africa, the only remaining full-time hunter-gatherers are the Hadza of Tanzania.[citation needed]

Ah, so..
some tribal societies
