Question

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.
The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water — a key to life as we know it on Earth — with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable 'Goldilocks' zone of a star — neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1.
What made it easier to record the passage of the planet in front of the star?
A) The fact that the star is much smaller and cooler than our Sun B) The fact that the star is much bigger and cooler than our Sun C) The fact that the star is much smaller and hotter than our Sun D) The fact that the star is much bigger and hotter than our Sun
