Question: Although most aspirated obstruents in the world's language are stops and affricates, aspirated fricatives such as [s], [f] or [] have been documented in Korean, in a few Tibeto-Burman languages, in some Oto-Manguean languages, and in the Siouan language Ofo. Some languages, such as Choni Tibetan, have up to four contrastive aspirated fricatives [s] [], [] and [x].
Try to answer this question if possible: Which language has up to five contrastive aspirated fricatives?
Answer: unanswerable
Question: In mid-1944 Japan mobilized over 500,000 men and launched a massive operation across China under the code name Operation Ichi-Go, their largest offensive of World War II, with the goal of connecting Japanese-controlled territory in China and French Indochina and capturing airbases in southeastern China where American bombers were based. During this time, many of the newest American-trained Chinese units and supplies were forcibly locked in the Burmese theater under Joseph Stilwell set by terms of the Lend-Lease Agreement. Though Japan suffered about 100,000 casualties, these attacks, the biggest in several years, gained much ground for Japan before Chinese forces stopped the incursions in Guangxi. Despite major tactical victories, the operation overall failed to provide Japan with any significant strategic gains. A great majority of the Chinese forces were able to retreat out of the area, and later come back to attack Japanese positions such as Battle of West Hunan. Japan was not any closer in defeating China after this operation, and the constant defeats the Japanese suffered in the Pacific meant that Japan never got the time and resources needed to achieve final victory over China. Operation Ichi-go created a great sense of social confusion in the areas of China that it affected. Chinese Communist guerrillas were able to exploit this confusion to gain influence and control of greater areas of the countryside in the aftermath of Ichi-go.
Try to answer this question if possible: Who was able to take advantage of the social confusion created by Operation Ichi-Go?
Answer: Chinese Communist guerrillas
Question: A videoconference system is generally higher cost than a videophone and deploys greater capabilities. A videoconference (also known as a videoteleconference) allows two or more locations to communicate via live, simultaneous two-way video and audio transmissions. This is often accomplished by the use of a multipoint control unit (a centralized distribution and call management system) or by a similar non-centralized multipoint capability embedded in each videoconferencing unit. Again, technology improvements have circumvented traditional definitions by allowing multiple party videoconferencing via web-based applications.
Try to answer this question if possible: How many locations can you use a videophone in?
Answer: unanswerable
Question: Much of the early paper made from wood pulp contained significant amounts of alum, a variety of aluminium sulfate salts that is significantly acidic. Alum was added to paper to assist in sizing, making it somewhat water resistant so that inks did not "run" or spread uncontrollably. Early papermakers did not realize that the alum they added liberally to cure almost every problem encountered in making their product would eventually be detrimental. The cellulose fibres that make up paper are hydrolyzed by acid, and the presence of alum would eventually degrade the fibres until the paper disintegrated in a process that has come to be known as "slow fire". Documents written on rag paper were significantly more stable. The use of non-acidic additives to make paper is becoming more prevalent, and the stability of these papers is less of an issue.
Try to answer this question if possible: Early papermakers added alum to help in what process?
Answer:
sizing
