Article: After just 100 hours of ground combat, and with all of Kuwait and much of southern Iraq under coalition control, US President George H. W. Bush ordered a cease-fire and negotiations began resulting in an agreement for cessation of hostilities. Some US politicians were disappointed by this move, believing Bush should have pressed on to Baghdad and removed Hussein from power; there is little doubt that coalition forces could have accomplished this if they had desired. Still, the political ramifications of removing Hussein would have broadened the scope of the conflict greatly, and many coalition nations refused to participate in such an action, believing it would create a power vacuum and destabilize the region.

Question: How long did ground combat operations last in the Persian Gulf War?
Ans: 100 hours


Article: Von Neumann made fundamental contributions in exploration of problems in numerical hydrodynamics. For example, with Robert D. Richtmyer he developed an algorithm defining artificial viscosity that improved the understanding of shock waves. A problem was that when computers solved hydrodynamic or aerodynamic problems, they tried to put too many computational grid points at regions of sharp discontinuity (shock waves). The mathematics of artificial viscosity smoothed the shock transition without sacrificing basic physics. Other well known contributions to fluid dynamics included the classic flow solution to blast waves, and the co-discovery of the ZND detonation model of explosives.

Question: What did the math of artificial viscosity do?
Ans: smoothed the shock transition without sacrificing basic physics


Article: This still left open the question of whether the opposite of approach in the prefrontal cortex is better described as moving away (Direction Model), as unmoving but with strength and resistance (Movement Model), or as unmoving with passive yielding (Action Tendency Model). Support for the Action Tendency Model (passivity related to right prefrontal activity) comes from research on shyness and research on behavioral inhibition. Research that tested the competing hypotheses generated by all four models also supported the Action Tendency Model.

Question: What model described the opposite of approach as unmoving but with resistance and strength?
Ans: Movement Model


Article: Paul VI was the first pope to receive an Anglican Archbishop of Canterbury, Michael Ramsey in official audience as Head of Church, after the private audience visit of Archbishop Geoffrey Fisher to Pope John XXIII on 2 December 1960. Ramsey met Paul three times during his visit and opened the Anglican Centre in Rome to increase their mutual knowledge. He praised Paul VI[e] and his contributions in the service of unity. Paul replied that "by entering into our house, you are entering your own house, we are happy to open our door and heart to you." The two Church leaders signed a common declaration, which put an end to the disputes of the past and outlined a common agenda for the future.

Question: Who was the first pope to meet with an Anglican Archbishop as an official Head of Church since 1960?
Ans:
Paul VI
