Question: On 7 August 1998, al-Qaeda struck the U.S. embassies in Kenya and Tanzania, killing 224 people, including 12 Americans. In retaliation, U.S. President Bill Clinton launched Operation Infinite Reach, a bombing campaign in Sudan and Afghanistan against targets the U.S. asserted were associated with WIFJAJC, although others have questioned whether a pharmaceutical plant in Sudan was used as a chemical warfare plant. The plant produced much of the region's antimalarial drugs and around 50% of Sudan's pharmaceutical needs. The strikes failed to kill any leaders of WIFJAJC or the Taliban.
Try to answer this question if possible: What percentage of Afghanistan's pharmaceutical needs were produced by the plant?
Answer: unanswerable
Question: Popper held that rationality is not restricted to the realm of empirical or scientific theories, but that it is merely a special case of the general method of criticism, the method of finding and eliminating contradictions in knowledge without ad-hoc-measures. According to this view, rational discussion about metaphysical ideas, about moral values and even about purposes is possible. Popper's student W.W. Bartley III tried to radicalise this idea and made the controversial claim that not only can criticism go beyond empirical knowledge, but that everything can be rationally criticised.
Try to answer this question if possible: What type of knowledge is not the only sphere of rational criticism, according to Popper's student W.W. Bartley III?
Answer: empirical
Question: Allusions to legal issues in To Kill a Mockingbird, particularly in scenes outside of the courtroom, has drawn the attention from legal scholars. Claudia Durst Johnson writes that "a greater volume of critical readings has been amassed by two legal scholars in law journals than by all the literary scholars in literary journals". The opening quote by the 19th-century essayist Charles Lamb reads: "Lawyers, I suppose, were children once." Johnson notes that even in Scout and Jem's childhood world, compromises and treaties are struck with each other by spitting on one's palm and laws are discussed by Atticus and his children: is it right that Bob Ewell hunts and traps out of season? Many social codes are broken by people in symbolic courtrooms: Mr. Dolphus Raymond has been exiled by society for taking a black woman as his common-law wife and having interracial children; Mayella Ewell is beaten by her father in punishment for kissing Tom Robinson; by being turned into a non-person, Boo Radley receives a punishment far greater than any court could have given him. Scout repeatedly breaks codes and laws and reacts to her punishment for them. For example, she refuses to wear frilly clothes, saying that Aunt Alexandra's "fanatical" attempts to place her in them made her feel "a pink cotton penitentiary closing in on [her]". Johnson states, "[t]he novel is a study of how Jem and Scout begin to perceive the complexity of social codes and how the configuration of relationships dictated by or set off by those codes fails or nurtures the inhabitants of (their) small worlds."
Try to answer this question if possible: What is another name for Scout's pink cotton penitentiary?
Answer: frilly clothes
Question: Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.
Try to answer this question if possible: What is the natural abundance of uranium-235?
Answer:
0.71%
