Managers in the Premier League are involved in the day-to-day running of the team, including the training, team selection, and player acquisition. Their influence varies from club-to-club and is related to the ownership of the club and the relationship of the manager with fans. Managers are required to have a UEFA Pro Licence which is the final coaching qualification available, and follows the completion of the UEFA 'B' and 'A' Licences. The UEFA Pro Licence is required by every person who wishes to manage a club in the Premier League on a permanent basis (i.e. more than 12 weeks the amount of time an unqualified caretaker manager is allowed to take control). Caretaker appointments are managers that fill the gap between a managerial departure and a new appointment. Several caretaker managers have gone on to secure a permanent managerial post after performing well as a caretaker; examples include Paul Hart at Portsmouth and David Pleat at Tottenham Hotspur.

During this period, Roman soldiers seem to have been modelled after those of the Etruscans to the north, who themselves seem to have copied their style of warfare from the Greeks. Traditionally, the introduction of the phalanx formation into the Roman army is ascribed to the city's penultimate king, Servius Tullius (ruled 578 to 534 BC). According to Livy and Dionysius of Halicarnassus, the front rank was composed of the wealthiest citizens, who were able to purchase the best equipment. Each subsequent rank consisted of those with less wealth and poorer equipment than the one before it.
Who introduced the phalanx formation into Rome's army?
****
The answer: Servius Tullius

With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterialsfor example, the sulfonamides, the quinolones, and the oxazolidinonesare produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]
How are the slufonamides,quinolones, and oxazolidinones created?
****
The answer: synthesis

The Diaz administration made political decisions and took legal measures that allowed the elite throughout Mexico to concentrate the nation's wealth by favoring monopolies. During this time, two-fifths of the state's territory was divided among 17 rich families which owned practically all of the arable land in Chihuahua. The state economy grew at a rapid pace during the Porfiriato; the economy in Chihuahua was dominated by agriculture and mining. The Diaz administration helped Governor Luis Terrazas by funding the Municipal Public Library in Chihuahua City and passing a federal initiative for the construction of the railroad from Chihuahua City to Ciudad Juarez. By 1881, the Central Mexican Railroad was completed which connected Mexico City to Ciudad Juarez. In 1883 telephone lines were installed throughout the state, allowing communication between Chihuahua City and Aldama. By 1888 the telephone services were extended from the capital to the cites of Julimes, Meoqui, and Hidalgo del Parral; the telecommunication network in the state covered an estimated 3,500 kilometers. The need of laborers to construct the extensive infrastructure projects resulted in a significant Asian immigration, mostly from China. Asian immigrants soon become integral to the state economy by opening restaurants, small grocery stores, and hotels. By the end of the Terrazas term, the state experienced an increase in commerce, mining, and banking. When the banks were nationalized, Chihuahua became the most important banking state in Mexico.
Two-fifths of the state's territory was divided between how many families?
****
The answer:
17
