QUES: Mali lies in the torrid zone and is among the hottest countries in the world. The thermal equator, which matches the hottest spots year-round on the planet based on the mean daily annual temperature, crosses the country. Most of Mali receives negligible rainfall and droughts are very frequent. Late June to early December is the rainy season in the southernmost area. During this time, flooding of the Niger River is common, creating the Inner Niger Delta. The vast northern desert part of Mali has a hot desert climate (Köppen climate classification (BWh) with long, extremely hot summers and scarce rainfall which decreases northwards. The central area has a hot semi-arid climate (Köppen climate classification (BSh) with very high temperatures year-round, a long, intense dry season and a brief, irregular rainy season. The little southern band possesses a tropical wet and dry climate (Köppen climate classification (Aw) very high temperatures year-round with a dry season and a rainy season.
Flooding of what river is typical during these months?

ANS: Niger River

QUES: Virgil is traditionally ranked as one of Rome's greatest poets. His Aeneid has been considered the national epic of ancient Rome from the time of its composition to the present day. Modeled after Homer's Iliad and Odyssey, the Aeneid follows the Trojan refugee Aeneas as he struggles to fulfill his destiny and arrive on the shores of Italy—in Roman mythology the founding act of Rome. Virgil's work has had wide and deep influence on Western literature, most notably Dante's Divine Comedy, in which Virgil appears as Dante's guide through hell and purgatory.
Where was Virgil born?

ANS: unanswerable

QUES: Together with caesium and gold (both yellow), and osmium (bluish), copper is one of only four elemental metals with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air. The characteristic color of copper results from the electronic transitions between the filled 3d and half-empty 4s atomic shells – the energy difference between these shells is such that it corresponds to orange light. The same mechanism accounts for the yellow color of gold and caesium.
How many metals have a natural color that isn't gray?

ANS: four

QUES: Clock shifts were found to increase the risk of heart attack by 10 percent, and to disrupt sleep and reduce its efficiency. Effects on seasonal adaptation of the circadian rhythm can be severe and last for weeks. A 2008 study found that although male suicide rates rise in the weeks after the spring transition, the relationship weakened greatly after adjusting for season. A 2008 Swedish study found that heart attacks were significantly more common the first three weekdays after the spring transition, and significantly less common the first weekday after the autumn transition. The government of Kazakhstan cited health complications due to clock shifts as a reason for abolishing DST in 2005. In March 2011, Dmitri Medvedev, president of Russia, claimed that "stress of changing clocks" was the motivation for Russia to stay in DST all year long. Officials at the time talked about an annual increase in suicides.
Which Russian president argued that the country should stay in DST year-round because of the stresses of time shifts?

ANS:
Dmitri Medvedev
