Question

Q.1 Read the following passage and answer the questions on the basis of [10]
comprehension of the passage (Any ten) -
The Sun appears to have been active for 4.6 billion years and has enough
fuel to go on for another five billion years or so. At the end of its life the
Sun will start to fuse helium into heavier elements and begin to swell up
ultimately growing so large that it will swallow the Earth. After a bilion
years as a red giant, it will suddenly collapse into a white dwarf- the final
end product of a star like ours. It may take a trillion years to cool off
completely. It just happens that the Moon and the Sun appear the same
size in the sky as viewed from the Earth. And since the Moon orbits the
Earth in approximately the same plane as the Earth's orbit around the
Sun, sometimes the Moon comes directly between the Earth and the Sun.
This is called a solar eclipse: if the alignment is slightly imperfect then the
Moon covers only a part of the Sun's disk and the event is called a partial
eclipse. When it lines up perfectly the entire solar disk is blocked and it is
called a total eclipse of the Sun.

Answer 1

Answer:

The Sun appears to have been active for 4.6 billion years and has enough

fuel to go on for another five billion years or so. At the end of its life the

Sun will start to fuse helium into heavier elements and begin to swell up

ultimately growing so large that it will swallow the Earth. After a bilion

years as a red giant, it will suddenly collapse into a white dwarf- the final

end product of a star like ours. It may take a trillion years to cool off

completely. It just happens that the Moon and the Sun appear the same

size in the sky as viewed from the Earth. And since the Moon orbits the

Earth in approximately the same plane as the Earth's orbit around the

Sun, sometimes the Moon comes directly between the Earth and the Sun.

This is called a solar eclipse: if the alignment is slightly imperfect then the

Moon covers only a part of the Sun's disk and the event is called a partial

eclipse. When it lines up perfectly the entire solar disk is blocked and it is

called a total eclipse of the Sun.
