Example Input: 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.

Example Input: Article: "Blogging is helping students to think and write more critically ,"says an Australian researcher, "and can help draw out people who would otherwise not engage in debate." These are the preliminary findings of PHD research by Anne Bartlett-Bragg, a lecturer at the University of Technology, Sydney, who has been using weblogs or blogs in her own teaching since 2001. "The students are thinking more critically." she says, "They are learning to be responsible and they're communicating outside the boundaries of the classroom and the institution, and they like that. "Bartlett-Bragg says in conventional teaching, students often rely on the lecturer as the main source of ideas and critique for their work. "I'm a bit over listening to my students giving me back in an essay what I've told them in class." she says. "I want them to think for themselves and get different perspectives." "What makes blogs useful is their interactive nature." she says. These web-based forums for discussing ideas, experiences or opinions allow students to discuss publicly what they are studying with other students and experts outside their own university. "I really encourage them to put their personal opinion in there, provided they are informed and backed up with evidence." Bartlett-Bragg says because a lot of academics in her field of electronic or e-learning now have their own blogs, students can engage directly with them. She says one of the most powerful facilities in weblogs is pinging, which involves a person positing a comment about someone else's work on their own blog. They use the "Trackback" tool to notify the author when they have published the comment, basically inviting them to discuss it. "They get such a buzz when they make a comment on another person outside the boundaries of the institution and that person responds, or even gives them some further reading." she says. "They are getting new perspectives that I can't give them in a normal lecture."
Question: What Bartlett-Bragg likes most is that blogs can help students to _ .
Options: (A) think for themselves (B) have stronger sense of responsibility (C) know more about the world outside (D) finish an essay assignment easily
