[EX Q]: Article: When Paul was a boy growing up in Utah, he happened to live near a copper smelter , and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him. Years later Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back. The answer from that big industry was "No". Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn't get his idea accepted. Paul later got married but his dream would not die. And then one night he did what he could with what he had. As Samuel Johnson wrote, "It is common to overlook what is near by keeping the eye fixed on something remote. Attainable good is often ignored by minds busied in wide ranges." Under the cover of darkness, he went secretly into the wasteland and started planting. And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against _ . Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing. Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.

[EX Q]: Article: Tragedy at the Circus In yesterday's circus show, a tiger suddenly attacked its trainer and had to be shot dead. As the circus packed up and left, circus officials said the show would go on, even without tigers. However, the officials cann't simply turn a blind eye to the ethical problems left behind. Even before this tragedy , animal rights activists protested against keeping wild animals in unnatural conditions and forcing them to suffer for the profit of circus organizers. It is now time for us to take effective steps to make sure that circus animals are treated properly. ******************************* Circus Safe for Animals Our circus recently suffered a most tragic event in its history. While we are thankful for the pity from the public, we are also astonished by the opinion expressed in "Tragedy at the Circus. " First, our performing animals are not taken from the wild. As to the ethical problems. we always believe humans and animals can--and should--live together nicely. To us, the performing animals are representatives of their species , and our circus is one of the only places left willing to support this special role of performing animals in the existence of the species. Those who argue that circus life is harmful to animals show little knowledge of these facts. Life in the "wild" is unsafe, but a continuous struggle for existence. To overlook these realities is the greatest fault against the animal kingdom. This circus has proven that animals are stronger and smarter than we could imagine. Within the circus is a joyful atmosphere for both animals and humans: people are educated, and species saved.
Question: What is the main purpose of the first passage?
