QUES: In 1964, Nikita Khrushchev was removed from his position of power and replaced with Leonid Brezhnev. Under his rule, the Russian SFSR and the rest of the Soviet Union went through an era of stagnation. Even after he died in 1982, the era didn't end until Mikhail Gorbachev took power and introduced liberal reforms in Soviet society.
Whose assumption of power ended the era of stagnation?

ANS: Mikhail Gorbachev

QUES: Genocide has become an official term used in international relations. The word genocide was not in use before 1944. Before this, in 1941, Winston Churchill described the mass killing of Russian prisoners of war and civilians as "a crime without a name". In that year, a Polish-Jewish lawyer named Raphael Lemkin, described the policies of systematic murder founded by the Nazis as genocide. The word genocide is the combination of the Greek prefix geno- (meaning tribe or race) and caedere (the Latin word for to kill). The word is defined as a specific set of violent crimes that are committed against a certain group with the attempt to remove the entire group from existence or to destroy them.
In 1941, how did Winston Churchill refer to the mass killings of Russian prisoners of war?

ANS: as "a crime without a name"

QUES: During her childhood, Madonna was inspired by actors, later saying, "I loved Carole Lombard and Judy Holliday and Marilyn Monroe. They were all incredibly funny ... and I saw myself in them ... my girlishness, my knowingness and my innocence." Her "Material Girl" music video recreated Monroe's look in the song "Diamonds Are a Girl's Best Friend", from the film Gentlemen Prefer Blondes (1953). She studied the screwball comedies of the 1930s, particularly those of Lombard, in preparation for the film Who's That Girl. The video for "Express Yourself" (1989) was inspired by Fritz Lang's silent film Metropolis (1927). The video for "Vogue" recreated the style of Hollywood glamour photographs, in particular those by Horst P. Horst, and imitated the poses of Marlene Dietrich, Carole Lombard, and Rita Hayworth, while the lyrics referred to many of the stars who had inspired her, including Bette Davis, described by Madonna as an idol. However, Madonna's film career has been largely received negatively by the film critic community. Stephanie Zacharek, critic for Time magazine, stated that, "[Madonna] seems wooden and unnatural as an actress, and it's tough to watch, because she's clearly trying her damnedest." According to biographer Andrew Morton, "Madonna puts a brave face on the criticism, but privately she is deeply hurt." After the box office bomb Swept Away (2002), Madonna vowed that she would never again act in a film, hoping her repertoire as a bad actress would never be discussed again.
Name one actor that Madonna was inspired by?

ANS: Marilyn Monroe

QUES: It would appear that living organisms are remarkably inefficient (in the physical sense) in their use of the energy they receive (chemical energy or radiation), and it is true that most real machines manage higher efficiencies. In growing organisms the energy that is converted to heat serves a vital purpose, as it allows the organism tissue to be highly ordered with regard to the molecules it is built from. The second law of thermodynamics states that energy (and matter) tends to become more evenly spread out across the universe: to concentrate energy (or matter) in one specific place, it is necessary to spread out a greater amount of energy (as heat) across the remainder of the universe ("the surroundings").[note 3] Simpler organisms can achieve higher energy efficiencies than more complex ones, but the complex organisms can occupy ecological niches that are not available to their simpler brethren. The conversion of a portion of the chemical energy to heat at each step in a metabolic pathway is the physical reason behind the pyramid of biomass observed in ecology: to take just the first step in the food chain, of the estimated 124.7 Pg/a of carbon that is fixed by photosynthesis, 64.3 Pg/a (52%) are used for the metabolism of green plants, i.e. reconverted into carbon dioxide and heat.
What are remarkably efficient in their use of the energy they receive?
