JAC Board Solution For Class 9TH English Prose Chapter 5
1. At the age of two-and-a-half, Einstein still wasn't talking
When he finally did learn to speak, he uttered everything twice.
Einstein did not know what to do with other children, and his
playmates called him "Brother Boring." So the youngster played
by himself much of the time. He especially loved mechanical toys,
Looking at his newborn sister, Maja,he is said to have said: "Fine
but where are her wheels?
Q. (a) Ilow did he speak when he started speaking?
(b) Why did his playmates call him 'Brother Boring?
(c) How did Einstein pass his time?
(d) How did he react to the birth of his sister Maja?
(e) Find a word from the passage which means 'spoke'.
Ans.(a) When Albert started speaking, he spoke everything
twice.
(b) He did not know what to do with other children. He
could not mix up with them. So they considered him to
be "Brother Boring:
(c) He passed it by playing by himself.
(d) He reacted saying where her wheels were.
(e) uttered'.
2. But Albert Einstein was not a bad pupil. He went to high
school in Munich, where Einstein's family had moved when he
was 15 months old, and scored good marks in almost every subject.
Einstein hated the school's regimentation, and often clashed with
his teachers. At the age of 15, Einstein felt so stifled there that he
left the school for good.
Q. (a) Where was Albert sent for his education?
(b) How was Einstein not a bad pupil?
(c) How did Einstein feel at school?
(d) What of school did Einstein hate?
(e) Find expressions from the passage which mean the
same as:
(i) army like discipline and order,
(ii) choked.
Ans.(a) Albert Einstein was sent for his education to his school
in Munich.
(b) He was not a bad pupil as he scored good marks in all
subjects.
(c) Einstein felt stifled due to harsh discipline which he
hated the most.
(d) He hated its regimentation.
(e) (i) army like discipline and order - regimentation,
(ii) choked - stifled.
3. He also felt a special interest in a fellow student, Mileva
Maric, whom he found to be a "clever creature." This young Serb
had come to Switzerland because the University in Zurich was one
of the few in Europe where women could get degrees. Einstein saw
in her an ally against the "philistines"- those people in his family
and at the university with whom he was constantly at odds. The
couple fell in love. Letters survive in which they put their affection
into words, mixing science with tenderness. Wrote Einstein: "How
happy and proud I shall be when we both have brought our work
on relativity to a victorious conclusion."
Q. (a) Who was the object of Albert's special interest in the
university?
(b) Why had Mileva come to Switzerland?
(c) How was Mileva an ally for Albert?
(d) How did Einstein and Mileva express love?
(e) Find a word from the passage which means 'friend'.
Ans. (a) Albert had special interest in his fellow student Mileva
Maric, besides Science.
(b) Mileva came to Switzerland to study in the university
of Zurich because it was one of the few universities in
the Europe which allowed higher studies for women.
(c) Mileva and Einstein both hated the authoritative and
philistine people around them. So Einstein found an
ally in Mileva.
(d) They expressed love with words mixing science with
tenderness.
(e) 'ally'.
4. Einstein's new personal chapter coincided with his rise to
world fame. In 1915, he had published his General Theory of
Relativity, which provided a new interpretation of gravity. An
eclipse of the sun in 1919 brought proof that it was accurate. Einstein
had correctly calculated in advance the extent to which the light
from fixed stars would be deflected through the sun's gravitational
field. The newspapers proclaimed his work as "a scientific
revolution."
Einstein received the Nobel Prize for Physics in 1921. He
was showered with honours and invitations from all over the world,
and lauded by the press.
Q. (a) Which theory did Einstein get published in 1915?
What did it state?
(b) Which natural phenomena proved Einstein theory?
(e) What had Einstein calculated in his 'General Theory
of Relativity?
(d) How was Einstein's work 'a scientific revolution'?
(e) Find words which mean the same as given in the
passage-
(i) definition (ii) declared.
Ans.(a) In 1915. Einstein published his 'General Theory of
Relativity'. It provided a new interpretation of the gravity.
(b) The Solar Eclipse of 1919 proved Einstein's theory.
(c) In his 'General Theory of Relativity, Einstein calculated
the extent of deflection of the light from the fixed stars
through the sun's gravitational field.
(d) Einstein's work was 'a scientific revolution' because he
calculated the things related to the distant heavenly
bodies four years in advance, that's too accurately.
(e) (i) definition - interpretation
(ii) declared - proclaimed.
5. Einsten was deeply shaken by the extent of the destruction
This time he wrote a public missive to the United Nations. In it he
proposed the formation of a world government. Unlike the letter
to Roosevelt, this one made no impact. But over the next decade,
Einstein got even more involved in politics - agitating for an end
to the arms buildup and using his popularity to campaign for
peace and democracy. When Einstein died in 1955 at the age of
76, he was celebrated as a visionary and world citizen as much as
a scientific genius.
Q. (a) What shook Einstein?
(b) Why did Einstein write to the U.N.
(c) What did Einstein propose in his letter to the United
Nations?
(d) For what political causes did Einstein fight/campaign?
(e) Find words from the passage which mean the same as-
(i) suggested (ii) the period of ten years.
Ans.(a) The extent of destruction caused by the America's
dropping atomic bomb on the Japanese cities Hiroshima
and Nagasaki in August, 1945 shook him deeply.
(b) Einstein wrote to United Nations to prevent any
repetition of the destruction caused by the Atomic bomb
in the future.
(c) In his letter to United Nations, Einstein proposed the
formation of a world government.
(d) Einstein campaigned for an end to the arms build up
and for peace and democracy.
(e) (i) suggested proposed
(ii) the period of ten years - decade.
Long Answer Type Quesions
Answer these questions in about 80-100 words cach:―
Q. 1. How was Albert Einstein a 'genius'?
Ans. Albert Einstein was highly gifted in mathematics and
greatly interested in science, especially physics. He worked on
relativity, light, motion of particles, the electrodynamics of moving
bodies and energy. He developed his special and General Theories
of relativity. In these he proved time and distance interdependent
and not absolute and the impact of sun's gravitational field on the
light's and its resultant deflection. He also established a formula to
describe relationship between mass and energy-E = mc²
Where, E = energy
m = Mass of the object
c = speed of light in the vacuum i.c. 300,000 km/s
Albert Einstein is one of the few real 'genius' scientists.
Q.2. What were Albert Einstein's contribution to the world
of science and humanity?
Or, How was Einstein a scientific genius' and a 'world
citizen'?
Ans. Albert Einstein contributed a lot to the world of science
and humanity. He worked on relativity, energy, space, time, the
motion of atoms, the electrodynamics of moving bodies etc. He
gave theories of relativities which changed the understanding of
space, time, and entire cosmos, gave a new interpretation to gravity.
His theories and formulae like E = mc2 greatly contributed for
scientific studies and are relevant forever. He was a 'scientific
genius'.
Besides, he fought against the arms race, and campaigned
for the international peace and democracy. He proposed a world
government. He remained actively involved in politics to assert
what was right for the future of the earth and common people.
Thus he was 'world citizen'.
Q.3. How did Albert Einstein's letter launch the arms race?
Or, Why did Einstein write to US President? What impact
did it have? Why was Einstein shaken?
Ans. Under the rule of Nazis, Germany developed its atomic
bomb and tested. At the urging of a colleague, Einstein wrote to
U.S. President Franklin D. Roosevelt, to warn him about the extent
of destruction it could have. He did so to prevent the America from
making atomic bomb and to persuade America to check such
activities in Germany. His words surely had impact but not the
expected one. Contrary to his suggestion, America developed its
own atomic bomb and dropped it on Japanese cities Hiroshima
and Nagasaki. Einstein was shaken to see the extent of destruction
it caused. In this way his letter launched the arms race.
