Read the excerpt from A Black Hole is NOT a Hole.

However, near a black hole, gases and dust and stars encounter its tug. Some things may be hurtling by so fast they won't get pulled into the black hole. Other things may not be as swift. They will be drawn in.

Closer and closer, the tugging force gets stronger and stronger. Close enough, the black hole no longer acts like a whirlpool.

With a whirlpool, there's always a fast-enough fish—or a fast-enough something—that moves so quickly it won't be pulled all the way into the center.

Not so with a black hole! Within a certain distance the black hole's power is so strong, nothing is fast enough to zip away.

Which line in this excerpt from the great gatsby by f. scott fitzgerald contains a simile? about half way between west egg and new york the motor-road hastily joins the railroad and runs beside it for a quarter of a mile, so as to shrink away from a certain desolate area of land. this is a valley of ashes—a fantastic farm where ashes grow like wheat into ridges and hills and grotesque gardens where ashes take the forms of houses and chimneys and rising smoke and finally, with a transcendent effort, of men who move dimly and already crumbling through the powdery air. occasionally a line of grey cars crawls along an invisible track, gives out a ghastly creak and comes to rest, and immediately the ash-grey men swarm up with leaden spades and stir up an impenetrable cloud which screens their obscure operations from your sight.
