Problem: Sahara:

The rainfall inhibition and the dissipation of cloud cover are most accentuated over the eastern section of the Sahara rather than the western. The prevailing air mass lying above the Sahara is the continental tropical (cT) air mass which is hot and dry. Hot, dry air masses primarily form over the North-African desert from the heating of the vast continental land area, and it affects the whole desert during most of the year. Because of this extreme heating process, a thermal low is usually noticed near the surface, and is the strongest and the most developed during the summertime. The Sahara High represents the eastern continental extension of the Azores High, centered over the North Atlantic Ocean. The subsidence of the Sahara High nearly reaches the ground during the coolest part of the year while it limits to the upper troposphere during the hottest periods.

When does the Azores High nearly reach the ground?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the U.S., for example, copyright case law contains a substantial similarity requirement to determine whether the work was copied. Likewise, courts may require computer software to pass an Abstraction-Filtration-Comparison test (AFC Test) to determine if it is too abstract to qualify for protection, or too dissimilar to an original work to be considered infringing. Software-related case law has also clarified that the amount of R&D, effort and expense put into a work's creation doesn't affect copyright protection.
What test might courts require hardware to pass to determine if it is protected or infringing?
A: unanswerable

Context and question: Ancient Greek philosophers like Thales, Anaxagoras (ca. 500 BC 428 BC), Epicurus and Democritus prefigure later materialists. The Latin poem De Rerum Natura by Lucretius (ca. 99 BC ca. 55 BC) reflects the mechanistic philosophy of Democritus and Epicurus. According to this view, all that exists is matter and void, and all phenomena result from different motions and conglomerations of base material particles called "atoms" (literally: "indivisibles"). De Rerum Natura provides mechanistic explanations for phenomena such as erosion, evaporation, wind, and sound. Famous principles like "nothing can touch body but body" first appeared in the works of Lucretius. Democritus and Epicurus however did not hold to a monist ontology since they held to the ontological separation of matter and space i.e. space being "another kind" of being, indicating that the definition of "materialism" is wider than given scope for in this article.
What kind of explanation does De Rerum Natura argue for rejecting phenomena?
Answer: unanswerable

Question: At this point, Fox whispered that there was "no loss of friendship". "I regret to say there is", Burke replied, "I have indeed made a great sacrifice; I have done my duty though I have lost my friend. There is something in the detested French constitution that envenoms every thing it touches". This provoked a reply from Fox, yet he was unable to give his speech for some time since he was overcome with tears and emotion, he appealed to Burke to remember their inalienable friendship, but also repeated his criticisms of Burke and uttered "unusually bitter sarcasms". This only aggravated the rupture between the two men. Burke demonstrated his separation from the party on 5 June 1791 by writing to Fitzwilliam, declining money from him.
Is there an answer to this question: Who thought that Fox and Burke's friendship was lost?

Answer: Burke

QUES: Compact Disc (CD) is a digital optical disc data storage format. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CDs and audio CD players have been commercially available since October 1982.
