Which selection from the article BEST supports the idea that the sun is necessary to the Earth?
(A) Although the sun is a rather ordinary star, it is very important to the inhabitants of Earth. The sun is the source of virtually all Earth’s energy. It provides the heat and light that make life on Earth possible.
(B) The average distance between the sun and Earth is roughly 93 million miles. Light travels through space at about 186,282 miles per second.
(C) The corona gives rise to a flow of charged particles called the solar wind that stretches beyond Earth and the other planets. The sun looks like a burning sphere.
(D) The vast amount of matter in the sun can provide the “fuel” for billions of years of atomic reactions. Astronomers believe that the sun is nearly halfway through its “lifetime” of 10 billion years.
Answer:I believe the answer is A
Explanation:
B and C have nothing to do with how the sun helps or is a necessity. D only talks about the life span of the sun not how it is necessary for the earth. A is the only answer that makes sense because it gives examples on how the sun helps the earth as well as human kind.
