Read this excerpt from A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano. In fact, every quasar and radio galaxy dot turned out to be energy from the center of an entire galaxy. Astronomers found stars careening around these centers, zooming at previously unheard-of speeds in their orbits. The motion was like an accelerating ice skater pulled around her partner in a tight twirl—or like a fish caught in a superstrong whirlpool. Something extreme had to be in the middle of each of those galaxies.

You might be able to guess what this was, but for scientists, the best answer came as a shock. In 1994 telescopic evidence confirmed the amazing cause: a supermassive black hole, with the mass not of one imploded star, not of two, but of millions—maybe even billions.

Which two parts of this excerpt from mary shelley’s frankenstein reveals information about the setting? (it was on a dreary night of november that i beheld the accomplishment of my toils.) with an anxiety that almost amounted to agony, (i collected the instruments of life around me, that i might infuse a spark of being into the lifeless thing that lay at my feet. it was already one in the morning; the rain pattered dismally against the panes, and my candle was nearly burnt out) when, by the glimmer of the half-extinguished light, i saw the dull yellow eye of the creature open; it breathed hard, and a convulsive motion agitated its limbs. (how can i describe my emotions at this catastrophe), or how delineate the wretch whom with such infinite pains and care i had endeavored to form? his limbs were in proportion, and i had selected his features as beautiful. beautiful! great god! (his yellow skin scarcely covered the work of muscles and arteries beneath; his hair was of a lustrous black, and flowing; his teeth of a pearly whiteness; ) but these luxuriances only formed a more horrid contrast with his watery eyes, that seemed almost of the same color as the dun-white sockets in which they were set, his shriveled complexion and straight black lips.

"i don't know," he said. "did you leave it in your mouth? it's the only place i can think of that's big enough." keyn laughed; something got stuck in his throat half way, and he coughed for breath. "i can see you're good to go,” tablin observed as keyn struggled to clear his throat. “go get your horse yourself before i take the job and leave you to rot in the flowing barrel."
