Question: Polyols, compounds containing more than one alcohol functional group, generally interact with cupric salts. For example, copper salts are used to test for reducing sugars. Specifically, using Benedict's reagent and Fehling's solution the presence of the sugar is signaled by a color change from blue Cu(II) to reddish copper(I) oxide. Schweizer's reagent and related complexes with ethylenediamine and other amines dissolve cellulose. Amino acids form very stable chelate complexes with copper(II). Many wet-chemical tests for copper ions exist, one involving potassium ferrocyanide, which gives a brown precipitate with copper(II) salts.
Is there an answer to this question: What does Schweizer's reagent dissolve?

Answer: cellulose

Question: PlayStation 3 uses the Cell microprocessor, designed by Sony, Toshiba and IBM, as its CPU, which is made up of one 3.2 GHz PowerPC-based "Power Processing Element" (PPE) and eight Synergistic Processing Elements (SPEs). The eighth SPE is disabled to improve chip yields. Only six of the seven SPEs are accessible to developers as the seventh SPE is reserved by the console's operating system. Graphics processing is handled by the NVIDIA RSX 'Reality Synthesizer', which can produce resolutions from 480i/576i SD up to 1080p HD. PlayStation 3 has 256 MB of XDR DRAM main memory and 256 MB of GDDR3 video memory for the RSX.
Is there an answer to this question: What does PPE stand for?

Answer: Power Processing Element

Question: During the period from 20002005 it is estimated that 49,722 people left the state for the United States. Some 82,000 people are thought to have immigrated to the state from 20002005 mainly coming from Veracruz (17.6%), United States (16.2%), Durango (13.2%), Coahuila (8.0%) and Chiapas (4.5%). It is believed that there is a large number of undocumented immigrants in that state the come from Central and South America which mainly settle in Ciudad Juarez. According to the 2005 census, the population grew 1.06% from 2000 to 2005. The state has an uneven settlement of people and the lowest population density of any Mexican state; according to the 2005 census there were 12 people per km2. Of all the 3,241,444 people in the state, two-thirds (2,072,129) live in the cities of Ciudad Juarez and Chihuahua. Only three other cities have populations over 100,000: Parral 101,147, Cuauhtemoc 105,725, and Delicias 108,187.
Is there an answer to this question: In which city is there a large number of undocumented immigrants?

Answer: Ciudad Juarez

Question: After the People's Republic of China took control of Mainland China in 1949, the Republic of China government based in Taiwan continued to control the Dachen Islands off the coast of Zhejiang until 1955, even establishing a rival Zhejiang provincial government there, creating a situation similar to Fujian province today. During the Cultural Revolution (196676), Zhejiang was in chaos and disunity, and its economy was stagnant, especially during the high tide (196669) of the revolution. The agricultural policy favoring grain production at the expense of industrial and cash crops intensified economic hardships in the province. Mao's self-reliance policy and the reduction in maritime trade cut off the lifelines of the port cities of Ningbo and Wenzhou. While Mao invested heavily in railroads in interior China, no major railroads were built in South Zhejiang, where transportation remained poor.
Is there an answer to this question: When did the People's Republic of China take control of Mainland China?

Answer:
1949
