Question: Read the following article and answer the question. Article: Do you want to know how and why a fall leaf changes color? We first have to understand what leaves are and what they do. Leaves are the world's food factories. Plants take water from the ground through their roots and take CO2from the air. Plants use sunlight to turn water and CO2into glucose , a kind of sugar. Plants use it as food for energy and growing. A chemical called _ in the leaves gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees "know" to begin getting ready for winter. During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples , sunlight and the cool nights of autumn turn the glucose in the leaves into a red colour. And we can enjoy the beautiful red leaves during autumn. Question: This passage tells us _ . Answer:
OPTIONS:
- the plants can grow well only with the sunlight
- there are all kinds of plants on the earth
- maple leaves change the color as other trees
- not all the colors of the leaves are from chlorophyll

Read the following article and answer the question. Article: Students who get tired of looking at the four walls of a classroom might like to take the nature course being offered by Carvel College again this summer. Groups of about a dozen students each, led by an experienced guide, will go on ten-day camping trips to the mountains to study the plants and animals that grow and live there. Students carry their own things, which includes sleeping bags, warm clothing, food and water, and other useful tools. And what do the students do all day? Well, as soon as the sun comes up, they eat breakfast and start climbing up the mountain trail to the next campground, which is five to ten miles away. As the students take notes, the guide points out different plants and animals alongside the trail. The climb is usually over by early afternoon, so the group spends the rest of the day resting or swimming in a mountain lake. Before dinner each night, they all come together and discuss the day's activities. At the end of the course, the students write reports using the information they have collected. But they don't mind at all. What they do mind is leaving the beauty of the wilderness and the good friends they've made to return to their normal lives in the city. Question: What can the course offer to the students? Answer:

OPTIONS:
- Better grades in tests.
- Free vacations in mountains.
- A different learning experience.
- Better chance to study in Carvel College.

Answer: A different learning experience.
