Problem: Alexander Graham Bell:

Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876.[N 4] Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study.[N 5]

What year did Bell get the patent for his telephone?

A: 1876

Problem: The Kpelle comprise more than 20% of the population and are the largest ethnic group in Liberia, residing mostly in Bong County and adjacent areas in central Liberia. Americo-Liberians, who are descendants of African American and West Indian, mostly Barbadian settlers, make up 2.5%. Congo people, descendants of repatriated Congo and Afro-Caribbean slaves who arrived in 1825, make up an estimated 2.5%. These latter two groups established political control in the 19th century which they kept well into the 20th century.
When did the decendents of West Indian settlers arrive in Liberia?

There are many approaches available in software testing. Reviews, walkthroughs, or inspections are referred to as static testing, whereas actually executing programmed code with a given set of test cases is referred to as dynamic testing. Static testing is often implicit, as proofreading, plus when programming tools/text editors check source code structure or compilers (pre-compilers) check syntax and data flow as static program analysis. Dynamic testing takes place when the program itself is run. Dynamic testing may begin before the program is 100% complete in order to test particular sections of code and are applied to discrete functions or modules. Typical techniques for this are either using stubs/drivers or execution from a debugger environment.
Name three approaches software testers take when testing their software?
A: Reviews, walkthroughs, or inspections

Context and question: There are special rules for certain rare diseases ("orphan diseases") in several major drug regulatory territories. For example, diseases involving fewer than 200,000 patients in the United States, or larger populations in certain circumstances are subject to the Orphan Drug Act. Because medical research and development of drugs to treat such diseases is financially disadvantageous, companies that do so are rewarded with tax reductions, fee waivers, and market exclusivity on that drug for a limited time (seven years), regardless of whether the drug is protected by patents.
Why are these companies rewarded?
Answer: Because medical research and development of drugs to treat such diseases is financially disadvantageous

Question: Although one of the main obstacles still facing the Egyptian economy is the limited trickle down of wealth to the average population, many Egyptians criticise their government for higher prices of basic goods while their standards of living or purchasing power remains relatively stagnant. Corruption is often cited by Egyptians as the main impediment to further economic growth. The government promised major reconstruction of the country's infrastructure, using money paid for the newly acquired third mobile license ($3 billion) by Etisalat in 2006. In the Corruption Perceptions Index 2013, Egypt was ranked 114 out of 177.
Is there an answer to this question: To what extent does wealth reach from affluent down to average population?

Answer: limited trickle down

QUES: Florida is served by Amtrak, operating numerous lines throughout, connecting the state's largest cities to points north in the United States and Canada. The busiest Amtrak train stations in Florida in 2011 were: Sanford (259,944), Orlando (179,142), Tampa Union Station (140,785), Miami (94,556), and Jacksonville (74,733). Sanford, in Greater Orlando, is the southern terminus of the Auto Train, which originates at Lorton, Virginia, south of Washington, D.C.. Until 2005, Orlando was also the eastern terminus of the Sunset Limited, which travels across the southern United States via New Orleans, Houston, and San Antonio to its western terminus of Los Angeles. Florida is served by two additional Amtrak trains (the Silver Star and the Silver Meteor), which operate between New York City and Miami. Miami Central Station, the city's rapid transit, commuter rail, intercity rail, and bus hub, is under construction.
