The intense speed of data transfer speed, has lead to the use of optical fibers. The optical fiber uses the technology of transferring light beams, from one end to the other end of optical cables. The attenuation in optical fiber is due to Scattering. The reason why scattering is caused, due to the folding, in the wire.

Q:

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.


The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water — a key to life as we know it on Earth — with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable 'Goldilocks' zone of a star — neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1.

 

What is the 'Goldilocks' zone?

A) It is a mythological place about stars and planets B) That place on a planet which has lowest possibility of liquid water.
C) The correct distance of a planet from its star to have possibility of having liquid water D) That place on a planet which has the right amount of sunlight
 
Answer & Explanation Answer: C) The correct distance of a planet from its star to have possibility of having liquid water

Man's attitude to various animals changed many times in the course of centuries. From indifference or practicality, he went on to adoration and deification, and then to hatred. Ancient Egyptians, for example, highly appreciated the cat's ability to destroy rodents. The cat was much superior in this respect to the grass­snakes and weasels they had kept in their houses before. These proved unable to cope with hordes of rats which invaded Egypt from Asia. So the cat, a very useful animal, was ranked as a sacred animal and one of the most important animals, too. The goddess of the Moon, fertility and child­birth, Bast herself was portrayed by the Egyptians as a woman with a cat's head.

Sumptuous temples were built to this goddess, where cats were kept in luxury and fed the choicest of foods. They had their own priests and votaries, more numerous as a matter of fact than any other sacred animal could boast. According to the Greek historian Herodotus, the festival in the city of Bubastis, which had a temple dedicated to cats, was attended by as many as 700 thousand, who brought their offerings to the goddess in the shape of figurines of her made of gold, silver and bronze and adorned with precious stones.

 

The word 'deification' in the passage means _____ .

A) highly valuable B) take pride
C) act of treating as God D) devotees
