Question

read the passage. there are several questions about this passage. from the elegant universe 1 isaac newton, born in 1642 in lincolnshire, england, changed the face of scientific research by bringing the full force of mathematics to the service of physical inquiry. newtons was such a monumental intellect that, for example, when he found that the mathematics required for some of his investigations did not exist, he invented it. nearly three centuries would pass before the world would host a comparable scientific genius. of newtons numerous profound insights into the workings of the universe, the one that primarily concerns us here is his universal theory of gravity. 2 the force of gravity pervades everyday life. it keeps us and all of the objects around us fixed to the earths surface; it keeps the air we breathe from escaping to outer space; it keeps the moon in orbit around the earth and it keeps the earth bound in orbit around the sun. gravity dictates the rhythm of the cosmic dance that is tirelessly and meticulously executed by billions upon billions of cosmic inhabitants, from asteroids to planets to stars to galaxies. more than three centuries of newtons influence causes us to take for granted that a single force—gravity—is responsible for this wealth of terrestrial and extraterrestrial happenings. but before newton there was no understanding that an apple falling to earth from a tree bore witness to the same physical principle that keeps the planets revolving around the sun. with an audacious step in the service of scientific hegemony, newton united the physics governing both heaven and earth and declared the force of gravity to be the invisible hand at work in each realm. 3 newtons view of gravity might be called the great equalizer. he declared that absolutely everything exerts an attractive gravitational force on absolutely everything else. regardless of physical composition, everything exerts as well as feels the force of gravity. based on a close study of johannes keplers analysis of planetary motion, newton deduced that the this sentence is from the passage. “with an audacious step in the service of scientific hegemony, newton united the physics governing both heaven and earth and declared the force of gravity to be the invisible hand at work in each realm.” (paragraph 2) how does this sentence help to develop a central idea of the text? 1. it provides evidence that newtons abilities far exceeded those of any other scientist, whether in his own time or in later centuries. 2. it adds details to the explanation of newtons theory of gravity by showing how gravity influences the motion of specific objects. 3. it suggests that newtons theory of gravity severely shocked the scientific community and met with resistance before it was finally accepted as a universal theory. 4. it highlights that by developing a universal principle that applies equally to the known world and to the distant unknown, newton did something of great scientific significance.

Explanation:

The sentence emphasizes Newton's achievement of creating a universal principle of gravity that applies to both earth - bound and celestial objects, highlighting its great scientific significance. It shows how Newton unified different physical realms under one theory.

Answer:

1. It highlights that by developing a universal principle that applies equally to the known world and to the distant unknown, Newton did something of great scientific significance.
