Problem: Please answer a question about the following article about Daylight saving time:
Common agreement about the day's layout or schedule confers so many advantages that a standard DST schedule has generally been chosen over ad hoc efforts to get up earlier. The advantages of coordination are so great that many people ignore whether DST is in effect by altering their nominal work schedules to coordinate with television broadcasts or daylight. DST is commonly not observed during most of winter, because its mornings are darker; workers may have no sunlit leisure time, and children may need to leave for school in the dark. Since DST is applied to many varying communities, its effects may be very different depending on their culture, light levels, geography, and climate; that is why it is hard to make generalized conclusions about the absolute effects of the practice. Some areas may adopt DST simply as a matter of coordination with others rather than for any direct benefits.
What indirect benefit of DST might cause some areas to observe it even though they don't get any direct benefits like cost or energy savings?
A: coordination with others


Question: Read this and answer the question

When the alloy cools and solidifies (crystallizes), its mechanical properties will often be quite different from those of its individual constituents. A metal that is normally very soft and malleable, such as aluminium, can be altered by alloying it with another soft metal, like copper. Although both metals are very soft and ductile, the resulting aluminium alloy will be much harder and stronger. Adding a small amount of non-metallic carbon to iron produces an alloy called steel. Due to its very-high strength and toughness (which is much higher than pure iron), and its ability to be greatly altered by heat treatment, steel is one of the most common alloys in modern use. By adding chromium to steel, its resistance to corrosion can be enhanced, creating stainless steel, while adding silicon will alter its electrical characteristics, producing silicon steel.

What kind of metal is soft like copper?
Answer: aluminium


Problem: In the past 20 years, several commercial streets have been developed, hence the nightlife has become more diverse: there are shopping malls opening late in the Xinjiekou CBD and Hunan Road. The well-established "Nanjing 1912" district hosts a wide variety of recreational facilities ranging from traditional restaurants and western pubs to dance clubs. There are two major areas where bars are densely located; one is in 1912 block; the other is along Shanghai road and its neighbourhood. Both are popular with international residents of the city.
What has happened as the result of more commercial streets in Nanjing?
The answer is the following: the nightlife has become more diverse


In the 1500s a new type of armor started to become popular due to the advent of firearms, new fighting tactics and the need for additional protection. The kozane dou made from individual scales was replaced by plate armor. This new armor, which used iron plated dou (dō), was referred to as Tosei-gusoku, or modern armor. Various other components of armor protected the samurai's body. The helmet kabuto was an important part of the samurai's armor. Samurai armor changed and developed as the methods of samurai warfare changed over the centuries. The known last use of samurai armor occurring in 1877 during the satsuma rebellion. As the last samurai rebellion was crushed, Japan modernized its defenses and turned to a national conscription army that used uniforms.
When was samurai armor last used?
1877


Input: CBC Television
Until 1998, the network carried a variety of American programs in addition to its core Canadian programming, directly competing with private Canadian broadcasters such as CTV and Global. Since then, it has restricted itself to Canadian programs, a handful of British programs, and a few American movies and off-network repeats. Since this change, the CBC has sometimes struggled to maintain ratings comparable to those it achieved before 1995, although it has seen somewhat of a ratings resurgence in recent years. In the 2007-08 season, hit series such as Little Mosque on the Prairie and The Border helped the network achieve its strongest ratings performance in over half a decade.

In what year did the network end American programming?
Output: 1998


Problem: Please answer a question about the following article about Institute of technology:
The nine largest and most renowned Technische Universitäten in Germany have formed TU9 German Institutes of Technology as community of interests. Technische Universitäten normally have faculties or departements of natural sciences and often of economics but can also have units of cultural and social sciences and arts. RWTH Aachen, TU Dresden and TU München also have a faculty of medicine associated with university hospitals (Klinikum Aachen, University Hospital Dresden, Rechts der Isar Hospital).
Which department's faculty can be associated with university hospitals?
A:
medicine
