Q.1-5. Read the following passage carefully and answer the given questions.
The prime planet listing has just appeared on the cosmic real estate market, possibly the most promising place yet to search for signs of life beyond the solar system, the astronomers who discovered it say. Exoplanet is a rocky orbit about one and a half times the size of Earth, about 40 light years from here. It circles a dwarf star known as LHS 1140
every 25 days, an orbit that puts it in the "Goldilocks" zone where temperatures are conducive to liquid water and perhaps life as we know it. It is close enough that astronomers are hopeful that with the next generation of big telescopes, they will be able to probe its atmosphere for signs of water or other evidence of suitability for life.

It is close enough that astronomers are hopeful that with the next generation of big telescopes, they will be able to probe its atmosphere for signs of water or other evidence of suitability for life.
This planet is really close to us: If we shrank the Milky Way to the size of the United States, LHS 1140 and the sun would fit inside Central Park. Charbonneau, who led the discovery team and is lead author of a paper published said in a statement, "This is the most exciting exoplanet I’ve seen in the last decade." The planet was discovered by the MEarth-South survey in Chile, an array of small telescopes that looks for the dips in starlight when planets pass in front of nearby stars.
The depth of the dip told them how big the new planet is. Then they determined that it was about six times as massive as Earth by using a spectrograph called Harps, for High Accuracy Radial velocity Planet Searcher, at the European Southern Observatory, to measure how much the planet perturbed its home star. The resulting density puts the little world into a rapidly growing class called "superEarths." The star LHS 1140 is about one-fifth the size of our sun. In its close orbit, the planet receives about half as much energy as Earth does from its own sun, enough for a microbe or something more complicated to make a living.

Q.4. What is the size of the star LHS 1140?
(A) It is about one-fifth the size of our sun.
(B) It is about one-third the size of our sun.

(D) Not mentioned in the passage.
Q.5. In its close orbit, how much energy does the planet receive?
(A) Same as much energy as Earth does from its own sun.
(B) Not as much energy as Earth does from its own sun.
(C) About half as much energy as Earth does from its own sun
(D) Both A and B
