Context and question: Described as being "sexy, seductive and provocative" when performing on stage, Beyoncé has said that she originally created the alter ego "Sasha Fierce" to keep that stage persona separate from who she really is. She described Sasha as being "too aggressive, too strong, too sassy [and] too sexy", stating, "I'm not like her in real life at all." Sasha was conceived during the making of "Crazy in Love", and Beyoncé introduced her with the release of her 2008 album I Am... Sasha Fierce. In February 2010, she announced in an interview with Allure magazine that she was comfortable enough with herself to no longer need Sasha Fierce. However, Beyoncé announced in May 2012 that she would bring her back for her Revel Presents: Beyoncé Live shows later that month.
Her alter ego was born when according to Beyonce?
Answer: making of "Crazy in Love"
Context and question: LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
What LED has the flattest I/V curve above the knee?
Answer: Red
Context and question: The first draft of the Convention included political killings, but these provisions were removed in a political and diplomatic compromise following objections from some countries, including the USSR, a permanent security council member. The USSR argued that the Convention's definition should follow the etymology of the term, and may have feared greater international scrutiny of its own Great Purge. Other nations feared that including political groups in the definition would invite international intervention in domestic politics. However leading genocide scholar William Schabas states: “Rigorous examination of the travaux fails to confirm a popular impression in the literature that the opposition to inclusion of political genocide was some Soviet machination. The Soviet views were also shared by a number of other States for whom it is difficult to establish any geographic or social common denominator: Lebanon, Sweden, Brazil, Peru, Venezuela, the Philippines, the Dominican Republic, Iran, Egypt, Belgium, and Uruguay. The exclusion of political groups was in fact originally promoted by a non-governmental organization, the World Jewish Congress, and it corresponded to Raphael Lemkin’s vision of the nature of the crime of genocide.” 
What atrocity motivated a self-serving USSR to object to the provision of political killings drafted into the Convention?
Answer:
its own Great Purge
