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 it, 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 billion 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
solar eclipse; if the alignment is slightly imperfect then the Moon covers only 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.
Choose the correct answer from the given option:
1) The fusing of helium into heavier element will result in
a) fusing of Sun b) end of Sun's life
C) swelling of Sun d) swelling of Earth
2) Partial eclipse occurs when
a) alignment is completely disturbed b) alignment is perfect
C) alignment is very much disturbed d) alignment is a little imperfect
3) Which word in the above passage is the antonym of ' dormant”?
a) collapse b) active
c) end d) dwarf
On the basis of the reading of the above passage, answer the following questions: 2x1 = 2
4) What is the end product of Stars?
5) What is solar eclipse?

Answer:
hi! how are you?
Explanation:
1. end of the Sun's life
2. Alignment is a little imperfect
3. Active
4. The end product of the Sun will be a white dwarf
5. Solar eclipse occurs when the moon comes in between the Sun and Earth. The moon covers all the sunlight coming from the Sun and there is darkness on some regions of the Earth. If the alignment is a bit imperfect the it will no longer be fully dark. The Earth will be partially dark.
Plz correct me if am wrong!
