Read the excerpt from "As Debris Piles Up, Americans Are Skeptical Enough Will Be Done to Limit Space Junk.” But most of the orbital debris is space-age flotsam and jetsam, such as spent rocket stages, screws and lens caps. There are about 23,000 detectable objects at least 2 to 4 inches in size in low-Earth orbit (the preferred altitude for most satellites and space missions) or about 1 to 3 feet in size in geostationary orbit (the ideal altitude for surveillance and communications satellites). What’s more, these objects can create more pieces of debris when they collide with one another or explode in orbit, due to leftover fuel or battery failures. Around 290 such "fragmentation events” are known to have occurred since 1961, creating an estimated 750,000 objects larger than about 0.5 inches in size. Circling the Earth at speeds around 10 times faster than a bullet, the kinetic energy of even miniscule objects can pack a punch strong enough to puncture the hull of a space station or damage solar panels and communication arrays. Before reading the article, Kimi skimmed the text features and predicted that the article would claim that most space junk is tiny and poses a minimal threat. Based on information in the text, which statement best revises Kimi’s prediction? The size of space junk varies depending on its orbit but is not dangerous in low-Earth orbit. Most space junk is 1 to 3 feet in size and is in geostationary orbit. Most small space junk is the result of fragmentation events and has very little kinetic energy. A lot of space junk is very small but can still cause significant damage.​

Select the correct text in the passage. which sentence in this excerpt from abraham lincoln's second inaugural address conveys that he wanted the us civil war to end as soon as possible? neither party expected for the war the magnitude or the duration which it has already attained. neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. each looked for an easier triumph, and a result less fundamental and astounding. both read the same bible and pray to the same god, and each invokes his aid against the other. it may seem strange that any men should dare to ask a just inging their bread from the sweat of other men's faces, but let us judge not, that we be not judged. the prayers of both could not be answered. that of neither has been answered fully. the almighty has his own purposes. "woe unto the world because of offenses, for it must needs be that offenses come, but woe to that man by whom the offense cometh" if we shall suppose that american slavery is one of those offenses which, in the providence of god, must needs come, but which, having continued through his appointed time, he now wills to remove, and that he gives to both north and south this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living god always ascribe to him? fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. yet, if god wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the lord are true and righteous altogether." reset next
