QUES: 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.

over what region is there the most cloud coverage?
What is the answer?
ANS: unanswerable
QUES: In 2010, a leaked cable revealed that Shell claims to have inserted staff into all the main ministries of the Nigerian government and know "everything that was being done in those ministries", according to Shell's top executive in Nigeria. The same executive also boasted that the Nigerian government had forgotten about the extent of Shell's infiltration. Documents released in 2009 (but not used in the court case) reveal that Shell regularly made payments to the Nigerian military in order to prevent protests.

About what did the Shell executive boast in relation to the leaked communication?
What is the answer?
ANS: the Nigerian government had forgotten about the extent of Shell's infiltration
QUES: Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely over relatively short distances and can change drastically in a short time. As an example, on November 11, 1911, the temperature at Oklahoma City reached 83 F (28 C) in the afternoon (the record high for that date), then an Arctic cold front of unprecedented intensity slammed across the state, causing the temperature to crash 66 degrees, down to 17 F (8 C) at midnight (the record low for that date); thus, both the record high and record low for November 11 were set on the same date. This type of phenomenon is also responsible for many of the tornadoes in the area, such as the 1912 Oklahoma tornado outbreak, when a warm front traveled along a stalled cold front, resulting in an average of about one tornado per hour over the course of a day.

How long did the 1912 tornado outbreak last?
What is the answer?
ANS:
a day
