Question: Read this and answer the question

When an electromagnetic wave strikes a plane surface such as the ground, part of the wave is transmitted into the ground and part of it is reflected, according to the Fresnel coefficients. If the ground is a very good conductor then almost all of the wave is reflected (180 out of phase), whereas a ground modeled as a (lossy) dielectric can absorb a large amount of the wave's power. The power remaining in the reflected wave, and the phase shift upon reflection, strongly depend on the wave's angle of incidence and polarization. The dielectric constant and conductivity (or simply the complex dielectric constant) is dependent on the soil type and is a function of frequency.

Is the ground has a great conductor, how much of the wave will be reflected?
Answer: 180 out of phase

Problem: In the early Sumerian Uruk period, the primitive pictograms suggest that sheep, goats, cattle, and pigs were domesticated. They used oxen as their primary beasts of burden and donkeys or equids as their primary transport animal and "woollen clothing as well as rugs were made from the wool or hair of the animals. ... By the side of the house was an enclosed garden planted with trees and other plants; wheat and probably other cereals were sown in the fields, and the shaduf was already employed for the purpose of irrigation. Plants were also grown in pots or vases."
When do the pictograms suggest Sumerians had domesticated livestock?
The answer is the following: Uruk period

New Haven has a history of professional sports franchises dating back to the 19th century and has been the home to professional baseball, basketball, football, hockey, and soccer teamsincluding the New York Giants of the National Football League from 1973 to 1974, who played at the Yale Bowl. Throughout the second half of the 20th century, New Haven consistently had minor league hockey and baseball teams, which played at the New Haven Arena (built in 1926, demolished in 1972), New Haven Coliseum (19722002), and Yale Field (1928present).
In what year was the New Haven Arena demolished?
1972

Input: Labour Party (UK)
In their first meeting after the election the group's Members of Parliament decided to adopt the name "The Labour Party" formally (15 February 1906). Keir Hardie, who had taken a leading role in getting the party established, was elected as Chairman of the Parliamentary Labour Party (in effect, the Leader), although only by one vote over David Shackleton after several ballots. In the party's early years the Independent Labour Party (ILP) provided much of its activist base as the party did not have individual membership until 1918 but operated as a conglomerate of affiliated bodies. The Fabian Society provided much of the intellectual stimulus for the party. One of the first acts of the new Liberal Government was to reverse the Taff Vale judgement.

Who was elected Chairman of the Parliamentary Labour Party?
Output: Keir Hardie

Input: Article: Thomas Barnes was appointed general editor in 1817. In the same year, the paper's printer James Lawson, died and passed the business onto his son John Joseph Lawson(18021852). Under the editorship of Barnes and his successor in 1841, John Thadeus Delane, the influence of The Times rose to great heights, especially in politics and amongst the City of London. Peter Fraser and Edward Sterling were two noted journalists, and gained for The Times the pompous/satirical nickname 'The Thunderer' (from "We thundered out the other day an article on social and political reform."). The increased circulation and influence of the paper was based in part to its early adoption of the steam-driven rotary printing press. Distribution via steam trains to rapidly growing concentrations of urban populations helped ensure the profitability of the paper and its growing influence.

Now answer this question: What kind of printing press helped increase the circulation and influence of The Times back in 1817?

Output: steam-driven rotary printing press

Problem: Canadian bitumen does not differ substantially from oils such as Venezuelan extra-heavy and Mexican heavy oil in chemical composition, and the real difficulty is moving the extremely viscous bitumen through oil pipelines to the refinery. Many modern oil refineries are extremely sophisticated and can process non-upgraded bitumen directly into products such as gasoline, diesel fuel, and refined asphalt without any preprocessing. This is particularly common in areas such as the US Gulf coast, where refineries were designed to process Venezuelan and Mexican oil, and in areas such as the US Midwest where refineries were rebuilt to process heavy oil as domestic light oil production declined. Given the choice, such heavy oil refineries usually prefer to buy bitumen rather than synthetic oil because the cost is lower, and in some cases because they prefer to produce more diesel fuel and less gasoline. By 2015 Canadian production and exports of non-upgraded bitumen exceeded that of synthetic crude oil at over 1.3 million barrels (21010^3 m3) per day, of which about 65% was exported to the United States.
What property of bitumen makes it difficult to move through pipelines?
The answer is the following:
extremely viscous
