On January 31, 2018, a rare ‘Blue Moon’ event was experienced in large parts of the globe. In that context consider the following statements : a. It was a rare moment as a blue moon, a super moon and a total lunar eclipse fell on the same day. b. When two full moons appear in the same calendar month, the second is termed as ‘Super moon’. c. When the full moon is at the closest point of its orbit to the Earth it is termed as ‘Blue moon’. The correct statement/s is/are :
The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.

The question below consists of a set of labelled sentences. Out of the four given options, select the most logical order of the sentences to form a coherent paragraph. P- Such a scenario allows for it to have a profound influence on the tides of our oceans, which in turn serves to slow earth’s rotation and hurl the moon further away from us. Q- The gravitational attraction of the moon is also the stabilising factor in a celestial battle between the large bodies of the solar system to throw the planet’s axial obliquity off-balance.  R- The bulk of the moon’s responsibility for impacting upon the planet lies with its gravitation and proximity to the earth. S- The very fact that the moon is here in the first place tells of how fortunate the impact that formed it was. Were it not for that humble collision over 4.5 billion years ago, life on earth would be vastly different today.
