Question

rizing and drawing conclusions in an informational text smarty - pants—somebody with a wild imagination. someone whose brain could surprise even himself. albert einstein didnt mean to turn the universe upside - down on everyone. he didnt plan on leading others to discover black holes. at first, all he set out to do was think about motion, along with a few other related ideas. but almost before he knew it, he had suddenly made our dependable old universe seem strange and new. einsteins spacey ideas before einstein, everyone pretty much thought of space as a sort of blank nothingness that separated objects like planets, solar systems, stars, and galaxies. this nothingness of space was a humongous, rigid background, with all of the matter in the universe arranged on it like pieces on a game board. they took care of the gaps in newtons theory and explained mercurys orbit. they led scientists to predict shifting starlight and black holes. all of this is powerful evidence that einstein was on to something. which detail should be included in a summary of this excerpt? scientists recognized einsteins ideas on curving space. einsteins ideas helped scientists predict shifting starlight and black holes. einstein worked hard to prove that his ideas were not \bizarre\ or strange. scientists knew that problems with newtons laws of gravity didnt explain mercurys orbit.

Explanation:

The text highlights how Einstein's ideas had far - reaching consequences, including helping scientists predict shifting starlight and black holes. This is a key point in the excerpt. The other options either are not mentioned (Einstein working hard to prove his ideas weren't strange) or are not the main focus (recognition of ideas on curving space is not the main take - away, and the statement about Newton not explaining Mercury's orbit is more of a background detail).

Answer:

Einstein's ideas helped scientists predict shifting starlight and black holes.
