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 orbitâup close to the Sunâhas a blip in it that Newton's laws can't explain.
Glitches like this one were the reason Einstein worked so hard at coming up with a new explanation. He wanted to account for everything. His ideas about curving space may sound bizarre, but they work! They took care of the gaps in Newton's theory and explained Mercury's orbit. They led scientists to predict shifting starlight and black holes. All of this is powerful evidence that Einstein was on to something.
However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing. Is an apple red (English) or rojo (Spanish)? It's okay to use either description.
Which detail should be left out of a summary of the excerpt?
Newtonâs rules explain a lot, but they do not work in high-gravity zones.
Einsteinâs ideas about curving space help explain gaps in Newtonâs laws.
Both Newtonâs and Einsteinâs ideas can work in different circumstances.
Newtonâs and Einsteinâs ideas are like the word âredâ in English or Spanish.

Read the quotation from "an occurrence at owl creek bridge." and now he became conscious of a new disturbance. striking through the thought of his dear ones was a sound which he could neither ignore nor understand, a sharp, distinct, metallic percussion like the stroke of a blacksmithââŹâ˘s hammer upon the anvil; it had the same ringing quality. he wondered what it was, and whether immeasurably distant or near byââŹâit seemed both. its recurrence was regular, but as slow as the tolling of a death knell. he awaited each stroke with impatience andââŹâhe knew not whyââŹâapprehension. the intervals of silence grew progressively longer, the delays became maddening. with their greater infrequency the sounds increased in strength and sharpness. they hurt his ear like the thrust of a knife; he feared he would shriek. what he heard was the ticking of his watch. which best describes the effect of the narration in the excerpt? it suggests that the man being executed feels tranquil and at peace. it suggests that the narrator is sympathetic to the man being executed. it suggests that the plot will become less tense as the story continues. it suggests that the story will become more intense and mysterious.
