Question

read the excerpt from \a black hole is not a hole\ by carolyn cinami decristofano. most of the time gravity seems to work the way newton described it. newton’s rules explain a lot, from falling apples to most planets’ orbits. but his laws don’t work perfectly. in high - gravity zones, newton’s ideas don’t jibe with what scientists observe. for example, mercury’s orbit—up close to the sun—has a blip in it that newton’s laws can’t explain. which detail best summarizes the excerpt? newtons laws of gravity worked most of the time. newtons laws of gravity were not perfect. newtons laws of gravity work perfectly in high - gravity zones. newtons laws of gravity explain the blip in mercurys orbit.

Explanation:

The text first notes Newton's gravity laws work often but then points out they aren't perfect, using Mercury's orbit as an example.

Answer:

Newton's laws of gravity were not perfect.
