Question: Read the following article and answer the question. Article: Goats are being hired to do the work of men in a neighborhood just outside of San Diego. The fires that occurred in Hillborough four years ago destroyed thirty homes, most of which have been rebuilt. While the home were rebuilt, the grasses, bushes, and shrubs were re-growing. The area is now so overgrown in brush that it again brings a major danger of fire. The city government asked for bids to remove the brush. The lowest bid they received was $50,000. And that was if the city provided breakfast and lunch for the work crews for the six weeks it would take to clear the overgrown area. The city government said no, offering unlimited coffee and a doughnut a day for each crew member. When that offer was rejected, the city asked for help on its website. A sheepherder in Montana and a goat-herder in San Bernardino read about the city's problem while surfing the web on their laptops. They both offered to do the job for $25,000. The government chose the goat-herder because he lived closer. When told that the city dump was overflowing, the goat-herder said, "No problem. My goats will eat everything in your dump. Except for the automobile engines, of course." So, for another $5,000, the city killed two birds with one stone. If all goes well, they will invite the goat-herder and his "family" back every three years. The goat-herder said he will probably visit San Diego while his goats are in the dump. "I want to go there by plane; I just hope we don't crash. My goats would miss me a lot," he said. Question: What are the "two birds" that the city government kills with only one stone? Answer:
OPTIONS:
- Both the sheepherder and goat-herder will work for the city for half of the money
- The danger of fire in a neighborhood and providing breakfast and lunch for the work crews.
- The danger of fire in a neighborhood and the overflowing dump.
- The city government can save some money and the goat-herder has a new job.
Answer: The danger of fire in a neighborhood and the overflowing dump.

Question: Read the following article and answer the question. Article: Across the United States, universities and colleges have been looking to become more sustainable and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living "green" at college. At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets. All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building world. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm's bio-garden, planting and harvesting fruits and vegetables. "I didn't have to worry about paper towels being wasted or feel bad about drying my clothes outside," Jeremy Lekich, the dorm's gardener, said. "Basically, it has made my life easier." Question: What can be inferred from the text? Answer:
OPTIONS:
- A long-term development calls for students' efforts.
- Students' ideas should be encouraged at college.
- Green living is a new trend at American colleges.
- Students can learn to protect the environment through practice.
Answer: Green living is a new trend at American colleges.

Question: Read the following article and answer the question. Article: What is an idiom? An idiom is a group of words which, when used together, has a different meaning from the one which the individual words have. For example, "---How do you know that Sid and Nancy have separated ?" "---I heard it on the grapevine ". Of course, the second speaker does not mean he heard the news about John by putting his ear to a grapevine! He is conveying the idea visually of information spreading around a widespread network, similar to a grapevine. We use idioms to express something that other words do not express as clearly or as cleverly. We often use an image or symbol to describe something as clearly as possible and thus make our point as effectively as possible. For example, "in a nutshell" suggests the idea of having all the information contained within very few words. Idioms tend to be informal and are best used in spoken rather than written English. One of the best ways to learn an idiom is by looking at the context in which it is used. This can be done by concentrating on the rest of the sentence and try to guess the meaning. Many idioms are not that difficult to understand when considered in their context. For example: We are going to have a surprise party for Tom tomorrow. It's a secret so please don't let the cat out of the bag. 'Let the cat out of the bag' is an idiom. Imagine you don't know what this idiom means; by looking at the words preceding, it should be easy to guess that the speaker does not want you to tell Tom about the surprise party. Therefore, 'let the cat out of the bag' must mean something like' reveal a secret' or 'tell a secret'. Question: It is most probable that idioms will be seen _ . Answer:
OPTIONS:
- in a paper
- in an preface
- in a notice
- in online chatting
Answer:
in online chatting
