Besides increased efficiency of power plants, there was an increase in efficiency (between 1950 and 1973) of the railway utilization of this electricity with energy-intensity dropping from 218 to 124 kwh/10,000 gross tonne-km (of both passenger and freight trains) or a 43% drop. Since energy-intensity is the inverse of energy-efficiency it drops as efficiency goes up. But most of this 43% decrease in energy-intensity also benefited diesel traction. The conversion of wheel bearings from plain to roller, increase of train weight, converting single track lines to double track (or partially double track), and the elimination of obsolete 2-axle freight cars increased the energy-efficiency of all types of traction: electric, diesel, and steam. However, there remained a 1215% reduction of energy-intensity that only benefited electric traction (and not diesel). This was due to improvements in locomotives, more widespread use of regenerative braking (which in 1989 recycled 2.65% of the electric energy used for traction,) remote control of substations, better handling of the locomotive by the locomotive crew, and improvements in automation. Thus the overall efficiency of electric traction as compared to diesel more than doubled between 1950 and the mid-1970s in the Soviet Union. But after 1974 (thru 1980) there was no improvement in energy-intensity (wh/tonne-km) in part due to increasing speeds of passenger and freight trains.
What type of locomotives got improved during 1950-1973 in Soviet Union?
electric

Input: Seven Years%27 War
For much of the eighteenth century, France approached its wars in the same way. It would let colonies defend themselves or would offer only minimal help (sending them limited numbers of troops or inexperienced soldiers), anticipating that fights for the colonies would most likely be lost anyway. This strategy was to a degree forced upon France: geography, coupled with the superiority of the British navy, made it difficult for the French navy to provide significant supplies and support to French colonies. Similarly, several long land borders made an effective domestic army imperative for any French ruler. Given these military necessities, the French government, unsurprisingly, based its strategy overwhelmingly on the army in Europe: it would keep most of its army on the continent, hoping for victories closer to home. The plan was to fight to the end of hostilities and then, in treaty negotiations, to trade territorial acquisitions in Europe to regain lost overseas possessions. This approach did not serve France well in the war, as the colonies were indeed lost, but although much of the European war went well, by its end France had few counterbalancing European successes.

How much effort did France put into wars to defend its colonies?
Output: It would let colonies defend themselves or would offer only minimal help

Input: Article: Imperial College Boat Club
The Imperial College Boat Club was founded on 12 December 1919. The Gold medal winning GB 8+ at the 2000 Sydney Olympics had been based at Imperial College's recently refurbished boathouse and included 3 alumni of the college along with their coach Martin McElroy. The club has been highly successful, with many wins at Henley Royal Regatta including most recently in 2013 with victory in The Prince Albert Challenge Cup event. The club has been home to numerous National Squad oarsmen and women and is open to all rowers not just students of Imperial College London.

Now answer this question: What was the name of the coach of the Gold medal winning GB8+?

Output: Martin McElroy

Article: The second-largest commercial airport is William P. Hobby Airport (named Houston International Airport until 1967) which operates primarily short- to medium-haul domestic flights. However, in 2015 Southwest Airlines launched service from a new international terminal at Hobby airport to several destinations in Mexico, Central America, and the Caribbean. These were the first international flights flown from Hobby since 1969. Houston's aviation history is showcased in the 1940 Air Terminal Museum located in the old terminal building on the west side of the airport. Hobby Airport has been recognized with two awards for being one of the top five performing airports in the world and for customer service by Airports Council International.

Question: Which airline now offers international flights from Hobby Airport?
Ans: Southwest Airlines

Here is a question about this article: West's musical career has been defined by frequent stylistic shifts, and has seen him develop and explore a variety of different musical approaches and genres throughout his work. When asked about his musical inspirations, he has named A Tribe Called Quest, Stevie Wonder, Michael Jackson, George Michael, LL Cool J, Phil Collins and Madonna as early interests. He has further described musician David Bowie as one of his "most important inspirations," and named producer Puff Daddy as the "most important cultural figure in my life." Early in his career, West pioneered a style of production dubbed "chipmunk soul" which utilized pitched-up vocal samples, usually from soul and R&B songs, along with his own drums and instrumentation. His first major release featuring his trademark soulful vocal sampling style was "This Can't Be Life", a track from Jay-Z's The Dynasty: Roc La Familia. West has said that Wu-Tang Clan producer RZA influenced him in his style, and has named Wu-Tang rappers Ghostface Killah and Ol' Dirty Bastard as inspirations. RZA spoke positively of the comparisons, stating in an interview for Rolling Stone, "All good. I got super respect for Kanye [...] [he] is going to inspire people to be like him." West further developed his style on his 2004 debut album, The College Dropout. After a rough version was leaked, he meticulously refined the production, adding string arrangements, gospel choirs, and improved drum programming.
What is the answer to this question: Kanye has stated that members from which rap group influenced his early style?
****
So... Wu-Tang Clan

Article: Transformation, unlike transduction or conjugation, depends on numerous bacterial gene products that specifically interact to perform this complex process, and thus transformation is clearly a bacterial adaptation for DNA transfer. In order for a bacterium to bind, take up and recombine donor DNA into its own chromosome, it must first enter a special physiological state termed competence (see Natural competence). In Bacillus subtilis, about 40 genes are required for the development of competence. The length of DNA transferred during B. subtilis transformation can be between a third of a chromosome up to the whole chromosome. Transformation appears to be common among bacterial species, and thus far at least 60 species are known to have the natural ability to become competent for transformation. The development of competence in nature is usually associated with stressful environmental conditions, and seems to be an adaptation for facilitating repair of DNA damage in recipient cells.

Question: How simple is the process of transformation?
Ans:
this complex process
