However, leeches and their closest relatives have a body structure that is very uniform within the group but significantly different from that of other annelids, including other members of the Clitellata. In leeches there are no septa, the connective tissue layer of the body wall is so thick that it occupies much of the body, and the two coelomata are widely separated and run the length of the body. They function as the main blood vessels, although they are side-by-side rather than upper and lower. However, they are lined with mesothelium, like the coelomata and unlike the blood vessels of other annelids. Leeches generally use suckers at their front and rear ends to move like inchworms. The anus is on the upper surface of the pygidium.

Question: What lines the coelomata of leeches?
Answer: mesothelium.

The Roman Empire reached its greatest territorial extent during the 2nd century AD; the following two centuries witnessed the slow decline of Roman control over its outlying territories. Economic issues, including inflation, and external pressure on the frontiers combined to make the 3rd century politically unstable, with emperors coming to the throne only to be rapidly replaced by new usurpers. Military expenses increased steadily during the 3rd century, mainly in response to the war with Sassanid Persia, which revived in the middle of the 3rd century. The army doubled in size, and cavalry and smaller units replaced the legion as the main tactical unit. The need for revenue led to increased taxes and a decline in numbers of the curial, or landowning, class, and decreasing numbers of them willing to shoulder the burdens of holding office in their native towns. More bureaucrats were needed in the central administration to deal with the needs of the army, which led to complaints from civilians that there were more tax-collectors in the empire than tax-payers.

There are two broad categories of public funding, direct, which entails a monetary transfer to a party, and indirect, which includes broadcasting time on state media, use of the mail service or supplies. According to the Comparative Data from the ACE Electoral Knowledge Network, out of a sample of over 180 nations, 25% of nations provide no direct or indirect public funding, 58% provide direct public funding and 60% of nations provide indirect public funding. Some countries provide both direct and indirect public funding to political parties. Funding may be equal for all parties or depend on the results of previous elections or the number of candidates participating in an election. Frequently parties rely on a mix of private and public funding and are required to disclose their finances to the Election management body.

Scholar Patrick Chura, who suggests Emmett Till was a model for Tom Robinson, enumerates the injustices endured by the fictional Tom that Till also faced. Chura notes the icon of the black rapist causing harm to the representation of the "mythologized vulnerable and sacred Southern womanhood". Any transgressions by black males that merely hinted at sexual contact with white females during the time the novel was set often resulted in a punishment of death for the accused. Tom Robinson's trial was juried by poor white farmers who convicted him despite overwhelming evidence of his innocence, as more educated and moderate white townspeople supported the jury's decision. Furthermore, the victim of racial injustice in To Kill a Mockingbird was physically impaired, which made him unable to commit the act he was accused of, but also crippled him in other ways. Roslyn Siegel includes Tom Robinson as an example of the recurring motif among white Southern writers of the black man as "stupid, pathetic, defenseless, and dependent upon the fair dealing of the whites, rather than his own intelligence to save him". Although Tom is spared from being lynched, he is killed with excessive violence during an attempted escape from prison, shot seventeen times.

Question: How many times was Tom shot?
Answer: seventeen.

In ancient times, Greece was the birthplace of Western culture. Modern democracies owe a debt to Greek beliefs in government by the people, trial by jury, and equality under the law. The ancient Greeks pioneered in many fields that rely on systematic thought, including biology, geometry, history, philosophy, physics and mathematics. They introduced such important literary forms as epic and lyric poetry, history, tragedy, and comedy. In their pursuit of order and proportion, the Greeks created an ideal of beauty that strongly influenced Western art.

People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 5 mg/m3 over a 15-minute period. Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that effect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 °C (390 °F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement.

Half the deported perished, and the other half were not allowed to return until the early 1960s (years after Stalin's death).[citation needed] The activities of Soviet forces in 1940–41 and after reoccupation sparked a guerrilla war against Soviet authorities in Estonia by the Forest Brothers, who consisted mostly of Estonian veterans of the German and Finnish armies and some civilians. This conflict continued into the early 1950s. Material damage caused by the world war and the following Soviet era significantly slowed Estonia's economic growth, resulting in a wide wealth gap in comparison with neighbouring Finland and Sweden.

By 1937, Japan controlled Manchuria and was ready to move deeper into China. The Marco Polo Bridge Incident on 7 July 1937 provoked full-scale war between China and Japan. The Nationalist and Communist Chinese suspended their civil war to form a nominal alliance against Japan, and the Soviet Union quickly lent support by providing large amount of materiel to Chinese troops. In August 1937, Generalissimo Chiang Kai-shek deployed his best army to fight about 300,000 Japanese troops in Shanghai, but, after three months of fighting, Shanghai fell. The Japanese continued to push the Chinese forces back, capturing the capital Nanking in December 1937 and committed which was known as Nanking Massacre. In March 1938, Nationalist forces won their first victory at Taierzhuang. but then the city of Xuzhou was taken by Japanese in May. In June 1938, Japan deployed about 350,000 troops to invade Wuhan and captured it in October. The Japanese achieved major military victories, but world opinion—in particular in the United States—condemned Japan, especially after the Panay Incident.

A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.

Question: What was the name given by Corbino to the incorrectly designated atomic number 94?

In a chapter of The Mathematical Foundations of Quantum Mechanics, von Neumann deeply analyzed the so-called measurement problem. He concluded that the entire physical universe could be made subject to the universal wave function. Since something "outside the calculation" was needed to collapse the wave function, von Neumann concluded that the collapse was caused by the consciousness of the experimenter (although this view was accepted by Eugene Wigner, the Von Neumann–Wigner interpretation never gained acceptance amongst the majority of physicists).

When discussing peer relationships among adolescents it is also important to include information in regards to how they communicate with one another. An important aspect of communication is the channel used. Channel, in this respect, refers to the form of communication, be it face-to-face, email, text message, phone or other. Teens are heavy users of newer forms of communication such as text message and social-networking websites such as Facebook, especially when communicating with peers. Adolescents use online technology to experiment with emerging identities and to broaden their peer groups, such as increasing the amount of friends acquired on Facebook and other social media sites. Some adolescents use these newer channels to enhance relationships with peers however there can be negative uses as well such as cyberbullying, as mentioned previously, and negative impacts on the family.

Several lines of evidence indicate lifestyle-induced hyperinsulinemia and reduced insulin function (i.e., insulin resistance) as a decisive factor in many disease states. For example, hyperinsulinemia and insulin resistance are strongly linked to chronic inflammation, which in turn is strongly linked to a variety of adverse developments such as arterial microinjuries and clot formation (i.e., heart disease) and exaggerated cell division (i.e., cancer). Hyperinsulinemia and insulin resistance (the so-called metabolic syndrome) are characterized by a combination of abdominal obesity, elevated blood sugar, elevated blood pressure, elevated blood triglycerides, and reduced HDL cholesterol. The negative impact of hyperinsulinemia on prostaglandin PGE1/PGE2 balance may be significant.

Before the 1950s, the department store held an eminent place in both Canada and Australia, during both the Great Depression and World War II. Since then, they have suffered from strong competition from specialist stores. Most recently the competition has intensified with the advent of larger-scale superstores (Jones et al. 1994; Merrilees and Miller 1997). Competition was not the only reason for the department stores' weakening strength; the changing structure of cities also affected them. The compact and centralized 19th century city with its mass transit lines converging on the downtown was a perfect environment for department store growth. But as residents moved out of the downtown areas to the suburbs, the large, downtown department stores became inconvenient and lost business to the newer suburban shopping malls. In 2003, U.S. department store sales were surpassed by big-box store sales for the first time (though some stores may be classified as "big box" by physical layout and "department store" by merchandise).

Humbert of Romans, the master general of the order from 1254 to 1263, was a great administrator, as well as preacher and writer. It was under his tenure as master general that the sisters in the order were given official membership. Humbert was a great lover of languages, and encouraged linguistic studies among the Dominicans, primarily Arabic, because of the missionary work friars were pursuing amongst those led astray or forced to convert by Muslims in the Middle East. He also wanted his friars to reach excellence in their preaching, and this was his most lasting contribution to the order. The growth of the spirituality of young preachers was his first priority. He once cried to his students: "... consider how excellent this office [of preaching] is, because it is apostolic; how useful, because it is directly ordained for the salvation of souls; how perilous, because few have in them, or perform, what the office requires, for it is not without great danger ... , vol. xxv. (Lyon, 1677)
