Explanation:
<h2>
Answer: D (or A, but I believe it's D)</h2>
Explanations
"A. A falling apple inspired Newton to think about gravity." Yes this is true, but instead of only thinking about it, he expressed his law of universal gravitation, etc. I understand how this could be the answer though. :>
"B. Gravity is when objects are pulled to the Earth." This is true aswell, but the text gives off more information than just what Gravity is. Newton is a big part of the text. Mostly the main character but narrating in third person.
"C. Newton wrote a series of books called Principia." Newton did this, but this isn't the main idea. If it was, the text would've explained more about it. This is more of a detail or maybe key detail.
"D. Newton discovers gravity.' I choose this as the correct answer because, the text talks about Newton discovering gravity, and when using the word discover in this, it's also like saying he discovered gravity from a falling apple, and contemplated about gravity.
