A. Read the passage carefully and answer the questions that
follows:(1x10=10)
Jagadish Chandra Bose had invented several sensitive instruments. One of them is
the Crescograph which is used to measure the growth rate of plants. Through his
experiments Bose showed that plants behave in the same manner as human
beings, although plants take longer to respond than animals. He proved that plants
are sensitive to heat, cold, light, noise and other external stimuli, just like human
beings. By injecting poison into a living plant Bose showed that they react in the
same manner as we do. Scientific research on electro-magnetic waves was initiated
by J. C. Bose in the late 19th century. It was the Italian scientist Marconi who got
the patent for the invention of wireless telegraphy. But we must remember that
Bose's public demonstration in Calcutta along the same lines happened much
earlier. Instead of looking for commercial benefit for his inventions, Bose made his
inventions public in order to allow others to advance further along the lines of his
research. However, Bose's place in history has now been re-evaluated. This great
Indian scientist was eventually crowned with glory when he was awarded
knighthood by the British Government in 1917. He was also conferred many other
awards like 'Fellow of the Royal Society', 'Companion of the Order of the Indian
Empire' etc. Needless to say, he is one of the greatest scientists ever born in our
country. Some of his famous books are "Response in the Living and the Non-living"
(1902), "The Nervous Mechanism of Plants"(1926), "Major Mechanism of
Plants"(1928) etc. In 1896, Bose wrote "Niruddesher Khoje", a science fiction. In
fact, he was the first writer of science fictions in Bengali. In November 1917, Bose
founded the 'Bose Institute' at his own house in Calcutta. He donated 'Bose
Institute' to the nation for research on Science.
1. Who got the patent for wireless telegraphy?

5. Write the names of two books written by J. C. Bose.
6. What instrument is used to measure the growth rate of the plants according to
the passage?
7. Find out the meaning of the following from the passage:
‘Official right to be the only person to make use of an invention’
8. Write True or False:
No other Bengali writer had written science fiction before J. C. Bose.
9. What did J. C. Bose donate for nation?
10. Find out the word which means same as the following:
‘An act of showing that something exists by giving proof or evidence’
