Which statement best summarizes "Save the Coral Reefs”?

Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

Development along the coastal regions has significant negative effects on coral reefs. The reefs are an essential part of the ocean’s ecosystem, and when people build structures on top of them, they are easily damaged because they are so fragile. We should limit construction along the coast to protect the reefs.

Construction along the coasts, overfishing, and bleaching have seriously damaged the world’s coral reefs. Since reefs are a very important part of the ocean’s ecosystem, their destruction has a devastating environmental impact, and we must work to protect them.

Coral reefs are fragile structures made of limestone. People who build in coastal regions and others who overfish our seas must be stopped, because they don’t care about all the species that rely on the survival of reefs, such as sea turtles, clownfish, lobster, sharks, and crabs.

Which excerpt from Silent Spring best appeals to readers’ pathos?

So it had been from the days many years ago when the first settlers raised their houses, sank their wells, and built their barns.

The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of color that flamed and flickered across a backdrop of pines.

The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and fall people traveled from great distances to observe them.

Yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. A grim specter has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know.

Read the paragraph from The Hot Zone.Just then, he noticed a blur of motion on his left, and he turned and saw two Hazleton workers walking toward him. They weren't supposed to be in here! The area was supposed to be sealed off, but they had come in by another route that led through a storeroom. They wore respirators, but nothing covered their eyes. When they saw the two men in space suits, they froze, speechless. Jerry could not see their mouths, but he could see their eyes, wide with astonishment. It was as if they had suddenly discovered that they were standing on the moon.

Read the excerpt from The Hot Zone.There she met Lieutenant Colonel Trotter, a stocky, dark-haired man whom Nancy had worked with for many years. They put on their inner gloves and taped their cuffs. Nancy put a pair of hearing protectors over her ears. She had started wearing them a while back, when people had begun to suspect that the roar of air in your suit might be loud enough to damage your hearing. They hauled on their space suits and sealed the Ziploc zippers. They edged around each other as they fiddled with their suits. People wearing biohazard space suits tend to step around one another like two wrestlers at the beginning of a match, watching the other person's every move, especially watching the hands to make sure they don't hold a sharp object. This cringing becomes instinctive.

It is always necessary to work with a partner when dealing with unidentified substances.

Extreme precautions must be taken when dealing with potentially hazardous materials.

Scientists are well known for being overly cautious and for taking unnecessary safety measures.

It is standard procedure to wear both space suits and hearing protectors in laboratories.

Read the excerpt from Silent Spring.It was a spring without voices. On the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.
