QUES: Plymouth lies between the River Plym to the east and the River Tamar to the west; both rivers flow into the natural harbour of Plymouth Sound. Since 1967, the unitary authority of Plymouth has included the, once independent, towns of Plympton and Plymstock which lie along the east of the River Plym. The River Tamar forms the county boundary between Devon and Cornwall and its estuary forms the Hamoaze on which is sited Devonport Dockyard.
In what body of water do the rivers Plym and Tamar meet?

ANS: Plymouth Sound

QUES: When military conflicts broke out between the Ottoman Empire and other states, Greeks usually took arms against the Empire, with few exceptions. Prior to the Greek revolution, there had been a number of wars which saw Greeks fight against the Ottomans, such as the Greek participation in the Battle of Lepanto in 1571, the Epirus peasants' revolts of 1600–1601, the Morean War of 1684–1699, and the Russian-instigated Orlov Revolt in 1770, which aimed at breaking up the Ottoman Empire in favor of Russian interests.[page needed] These uprisings were put down by the Ottomans with great bloodshed.
The Battle of of Lepanto took place in what year?

ANS: 1571

QUES: Politics & Policy was founded at Northwestern and is dedicated to the analysis of current events and public policy. Begun in 2010 by students in the Weinberg College of Arts and Sciences, School of Communication, and Medill School of Journalism, the organization reaches students on more than 250 college campuses around the world. Run entirely by undergraduates, Politics & Policy publishes several times a week with material ranging from short summaries of events to extended research pieces. The organization is funded in part by the Buffett Center.
How many college campuses does Politics & Policy reach worldwide?

ANS: 250

QUES: The simplest method, used for small-scale production and often by hobbyists, is immersion etching, in which the board is submerged in etching solution such as ferric chloride. Compared with methods used for mass production, the etching time is long. Heat and agitation can be applied to the bath to speed the etching rate. In bubble etching, air is passed through the etchant bath to agitate the solution and speed up etching. Splash etching uses a motor-driven paddle to splash boards with etchant; the process has become commercially obsolete since it is not as fast as spray etching. In spray etching, the etchant solution is distributed over the boards by nozzles, and recirculated by pumps. Adjustment of the nozzle pattern, flow rate, temperature, and etchant composition gives predictable control of etching rates and high production rates.
What gives unpredictable control of etching rates and high production rates?

ANS:
unanswerable
