Pаrt 1: Errоr CоrrectiоnReаd the following аrticle. There are 15 errors in topics we've covered this semester. Find and correct at least 10 of them. You will not be graded down for wrong answers, so try to find all 15.Corals Survived Past Climate Changes by Retreating to the DeepsNouns, Pronouns, and Articles 1 |    In the summer of 2023, the water around the Florida Keys became so hot that many  2 | corals simply could not survive. A long marine heat wave pushed water temperatures  3 | several degrees above normal for weeks. When scientists went back to check reef, they  4 | found that two important reef-building corals, staghorn and elkhorn, had suffered what she  5 | called “functional extinction.” A few individual were still alive, but there were so few that  6 | the species can no longer grow or reproduce normally in most parts of the Florida Reef.Word Forms / Gerunds and Infinitives 7 |    Heat waves kill corals in an indirect but destruction way. Inside the coral’s tissues  8 | live symbiotic microalgae that use sunlight to make sugar. Normally, this partnership feeds  9 | the coral and gives it a warm, brownish color. When the water gets too hot, however, the 10 | algae start to producing toxic forms of oxygen instead of food. To protect itself, the coral 11 | pushes the algae out of its body. This process, called bleaching, removes the toxin but also 12 | cuts off the coral’s main food source. If the high temperatures last too long, the starving 13 | corals die.Independent Clauses and Adverb Clauses14 |    The 2023 event was the ninth recorded marine heat wave in the region, it was much 15 | more intense than any of the earlier ones. Researchers reported that in the Dry Tortugas, at 16 | the southern tip of the reef, every monitored staghorn and elkhorn coral died. In the Lower 17 | and Middle Keys, as well as most of the Upper Keys. Mortality stayed near 100 percent. 18 | Only near Miami, where local currents kept the water a little cooler, did more than a third 19 | of the Acropora corals survive. Even there, most of the population disappeared.Verb Tense/Aspect20 |    This sudden collapse are frightening, but corals as a group are not fragile 21 | newcomers. Stony corals have exist for roughly 460 million years and have already passed 22 | through several mass extinction events. A recent study looked at the DNA of 274 modern 23 | coral species and compared those results with the fossil record. The researchers concluded 24 | that the earliest stony coral was probably a solitary animal, not a member of a colony, and 25 | it did not hosted algae inside its tissues. Because it made its own food by catching prey, it 26 | did not bleach when temperatures rose and could live in both shallow and deep water.Adjective Clauses27 |    Over long periods of time, different branches of the coral “family” evolved new 28 | strategies. Some began to live in colonies that they built large reefs. Others formed tight 29 | partnerships with algae that let them grow quickly in clear, sunlit water. These shallow-30 | water species created the colorful tropical reefs we know today, but they also became more 31 | sensitive to changes in temperature and water chemistry. During past crises, such as 32 | sudden global warming or rapid acidification of the oceans, as many as 90 percent of these 33 | shallow, colonial corals died out. Corals who were deeper and less specialized survived 34 | and slowly spread back toward the surface, starting the reef-building cycle again.Noun Clauses35 |    Scientists tell the drawback is that this natural reset happens on geological 36 | timescales. One estimate suggests what it can take four to five million years for coral 37 | diversity and reef structures to recover after a major extinction event. Human societies, of 38 | course, cannot wait that long. As the Florida Reef weakens, storms are likely to cause more 39 | flooding and erosion, and many species that depend on the reef may decline or vanish.Modals40 |    Because of these risks, researchers are testing ways to help corals adapt more 41 | quickly than evolution alone would allow. One strategy is to crossbreed Florida corals with 42 | individuals from warmer regions in the hope of producing offspring that can tolerating 43 | higher temperatures. None of these interventions is simple, and they will not completely 44 | solve the problem of rising ocean temperatures. Still, they may have buy time. On their 45 | own, corals will probably survive our current experiment with the climate and rebuild their 46 | reefs millions of years from now. The challenge is whether we can protect them, and 47 | ourselves, in the much shorter time scales that matter to human life.
