Article: The first PCBs used through-hole technology, mounting electronic components by leads inserted through holes on one side of the board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides. Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on the back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends. Leads may be soldered either manually or by a wave soldering machine.

Question: For boards with two sides, to what angle are leads bent to in order to install them horizontally?
Ans: 90 degrees


Article: French police were criticised for their handling of the events, and notably for confiscating Tibetan flags from demonstrators. The newspaper Libération commented: "The police did so much that only the Chinese were given freedom of expression. The Tibetan flag was forbidden everywhere except on the Trocadéro." Minister of the Interior Michèle Alliot-Marie later stated that the police had not been ordered to do so, and that they had acted on their own initiative. A cameraman for France 2 was struck in the face by a police officer, knocked unconscious, and had to be sent to hospital.

Question: Who said the police acted on their own in taking the flags?
Ans: Michèle Alliot-Marie


Article: West's third studio album, Graduation, garnered major publicity when its release date pitted West in a sales competition against rapper 50 Cent's Curtis. Upon their September 2007 releases, Graduation outsold Curtis by a large margin, debuting at number one on the U.S. Billboard 200 chart and selling 957,000 copies in its first week. Graduation once again continued the string of critical and commercial successes by West, and the album's lead single, "Stronger", garnered the rapper his third number-one hit. "Stronger", which samples French house duo Daft Punk, has been accredited to not only encouraging other hip-hop artists to incorporate house and electronica elements into their music, but also for playing a part in the revival of disco and electro-infused music in the late 2000s. Ben Detrick of XXL cited the outcome of the sales competition between 50 Cent's Curtis and West's Graduation as being responsible for altering the direction of hip-hop and paving the way for new rappers who didn't follow the hardcore-gangster mold, writing, "If there was ever a watershed moment to indicate hip-hop's changing direction, it may have come when 50 Cent competed with Kanye in 2007 to see whose album would claim superior sales."

Question: How many copies did Graduation sell in its first week of release? 
Ans: 957,000


Article: The genocide was implemented in two phases: the wholesale killing of the able-bodied male population through massacre and subjection of army conscripts to forced labour, followed by the deportation of women, children, the elderly and infirm on death marches leading to the Syrian desert. Driven forward by military escorts, the deportees were deprived of food and water and subjected to periodic robbery, rape, and massacre. There was local Armenian resistance in the region, developed against the activities of the Ottoman Empire. The events of 1915 to 1917 are regarded by Armenians and the vast majority of Western historians to have been state-sponsored mass killings, or genocide.

Question: What do the Armenians see the events of 1915-1917 as?
Ans:
state-sponsored mass killings, or genocide
