Problem: Please answer a question about the following article about Chinese characters:
Written Japanese also includes a pair of syllabaries known as kana, derived by simplifying Chinese characters selected to represent syllables of Japanese. The syllabaries differ because they sometimes selected different characters for a syllable, and because they used different strategies to reduce these characters for easy writing: the angular katakana were obtained by selecting a part of each character, while hiragana were derived from the cursive forms of whole characters. Modern Japanese writing uses a composite system, using kanji for word stems, hiragana for inflexional endings and grammatical words, and katakana to transcribe non-Chinese loanwords as well as serve as a method to emphasize native words (similar to how italics are used in Romance languages).
What uses a composite system?
A: Modern Japanese writing
Problem: Please answer a question about the following article about Arena Football League:
Following the suspension of the AFL's 2009 season, league officials and owners of af2 (which had played its season as scheduled) began discussing the future of arena football and the two leagues. With its 50.1 percent ownership of af2, the AFL's bankruptcy and dissolution prompted the dissolution of af2 as well. That league was formally considered disbanded on September 8, 2009, when no owner committed his or her team to the league's eleventh season by that deadline. For legal reasons, af2 league officials and owners agreed to form a new legal entity, Arena Football 1 (AF1), with former AFL teams the Arizona Rattlers and Orlando Predators joining the former af2.
What percent of af2 was owned by the AFL?
A: 50.1
Problem: Please answer a question about the following article about Memory:
However, memory performance can be enhanced when material is linked to the learning context, even when learning occurs under stress. A separate study by cognitive psychologists Schwabe and Wolf shows that when retention testing is done in a context similar to or congruent with the original learning task (i.e., in the same room), memory impairment and the detrimental effects of stress on learning can be attenuated. Seventy-two healthy female and male university students, randomly assigned to the SECPT stress test or to a control group, were asked to remember the locations of 15 pairs of picture cards a computerized version of the card game "Concentration" or "Memory". The room in which the experiment took place was infused with the scent of vanilla, as odour is a strong cue for memory. Retention testing took place the following day, either in the same room with the vanilla scent again present, or in a different room without the fragrance. The memory performance of subjects who experienced stress during the object-location task decreased significantly when they were tested in an unfamiliar room without the vanilla scent (an incongruent context); however, the memory performance of stressed subjects showed no impairment when they were tested in the original room with the vanilla scent (a congruent context). All participants in the experiment, both stressed and unstressed, performed faster when the learning and retrieval contexts were similar.
What can impact memory performance in a positive way?
A: when material is linked to the learning context,
Problem: Please answer a question about the following article about Napoleon:
There have been modern studies that have supported the original autopsy finding. In a 2008 study, researchers analysed samples of Napoleon's hair from throughout his life, as well as samples from his family and other contemporaries. All samples had high levels of arsenic, approximately 100 times higher than the current average. According to these researchers, Napoleon's body was already heavily contaminated with arsenic as a boy, and the high arsenic concentration in his hair was not caused by intentional poisoning; people were constantly exposed to arsenic from glues and dyes throughout their lives.[note 7] Studies published in 2007 and 2008 dismissed evidence of arsenic poisoning, and confirmed evidence of peptic ulcer and gastric cancer as the cause of death.
Studies published in 2007 and 2008 support what possible causes of Napoleon's death?
A:
peptic ulcer and gastric cancer
