Input: Article: Argentine activists told a news conference that they would not try to snuff out the torch's flame as demonstrators had in Paris and London. "I want to announce that we will not put out the Olympic torch," said pro-Tibet activist Jorge Carcavallo. "We'll be carrying out surprise actions throughout the city of Buenos Aires, but all of these will be peaceful." Among other activities, protesters organized an alternative march that went from the Obelisk to the city hall, featuring their own "Human Rights Torch." A giant banner reading "Free Tibet" was also displayed on the torch route. According to a representative from the NGO 'Human Rights Torch Relay', their objective was to "show the contradiction between the Olympic Games and the presence of widespread human rights violations in China"

Now answer this question: What is the name of the protester who said they would not try to extinguish the torch?

Output: Jorge Carcavallo.

Article: The classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC (some authors prefer to split this period into 'Classical', from the end of the Persian wars to the end of the Peloponnesian War, and 'Fourth Century', up to the death of Alexander). It is so named because it set the standards by which Greek civilization would be judged in later eras. The Classical period is also described as the "Golden Age" of Greek civilization, and its art, philosophy, architecture and literature would be instrumental in the formation and development of Western culture.

Question: The time span that is counted as the classical for the Greeks is from eras ?
Ans: classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC

Here is a question about this article: In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.
What is the answer to this question: What year could be marked as year when electric railways more efficient than diesel ones?
****
So... 1965

Linguistic anthropology (also called anthropological linguistics) seeks to understand the processes of human communications, verbal and non-verbal, variation in language across time and space, the social uses of language, and the relationship between language and culture. It is the branch of anthropology that brings linguistic methods to bear on anthropological problems, linking the analysis of linguistic forms and processes to the interpretation of sociocultural processes. Linguistic anthropologists often draw on related fields including sociolinguistics, pragmatics, cognitive linguistics, semiotics, discourse analysis, and narrative analysis.
What subdivision of anthropology seeks to understand the process of human communications?
****
The answer: Linguistic

Problem: Please answer a question about the following article about Daylight saving time:
Industrialized societies generally follow a clock-based schedule for daily activities that do not change throughout the course of the year. The time of day that individuals begin and end work or school, and the coordination of mass transit, for example, usually remain constant year-round. In contrast, an agrarian society's daily routines for work and personal conduct are more likely governed by the length of daylight hours and by solar time, which change seasonally because of the Earth's axial tilt. North and south of the tropics daylight lasts longer in summer and shorter in winter, the effect becoming greater as one moves away from the tropics.
What is the tilt of the Earth that causes solar time to change called?
A: axial tilt

Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UTin which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.

When did observations at the Greenwich Observatory cease?
Answer:
1954
