Problem: 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.
GMT used what instead of atomic clocks?
The answer is the following: telescopes

Problem: The use of alloys by humans started with the use of meteoric iron, a naturally occurring alloy of nickel and iron. It is the main constituent of iron meteorites which occasionally fall down on Earth from outer space. As no metallurgic processes were used to separate iron from nickel, the alloy was used as it was. Meteoric iron could be forged from a red heat to make objects such as tools, weapons, and nails. In many cultures it was shaped by cold hammering into knives and arrowheads. They were often used as anvils. Meteoric iron was very rare and valuable, and difficult for ancient people to work.
What is meteoric iron composed of?
The answer is the following: nickel and iron

Problem: Kathmandu is a center for art in Nepal, displaying the work of contemporary artists in the country and also collections of historical artists. Patan in particular is an ancient city noted for its fine arts and crafts. Art in Kathmandu is vibrant, demonstrating a fusion of traditionalism and modern art, derived from a great number of national, Asian, and global influences. Nepali art is commonly divided into two areas: the idealistic traditional painting known as Paubhas in Nepal and perhaps more commonly known as Thangkas in Tibet, closely linked to the country's religious history and on the other hand the contemporary western-style painting, including nature-based compositions or abstract artwork based on Tantric elements and social themes of which painters in Nepal are well noted for. Internationally, the British-based charity, the Kathmandu Contemporary Art Centre is involved with promoting arts in Kathmandu.
Contemporary Kathmandu art combines traditional influences with what type of art?
The answer is the following:
modern
