Read the following article and select the best answer. Article: New findings from Queen's University biologists show that in the plant world, bigger isn't necessarily better. "Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant," says Queen's Biology professor Lonnie Aarssen. "But our research shows it's virtually the other way around." Previous studies showed that larger plant species monopolize sunlight, water and other resources, limiting the number of smaller plant species that can exist around them. But the research has proved that _ is not generally the case in natural vegetation. In the Queen's project, PhD student Laura Keating targeted the largest "host plants" of 16 woody plant species growing in the Okanogan Valley, British Columbia. The research team calculated the number and variety of plants that neighbored each large host plant. They then randomly selected plots without host plants and calculated the plant species there as well. The research showed that the massive trees have no effect on the number of species with which they coexist. Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen notes. Larger species generate physical space niches under their shelters where smaller species grow well. Smaller plants are much more effective than large trees at using available resources. They also produce seeds at a much younger age and higher rate than their bigger counterparts, and settle down much more quickly--thuscompeting with the newly-born plants of larger species. Question: What's the main idea of the text? - Smaller plants may have many advantages over their neighbors. - In the plant world, the bigger is better than the smaller one. - To be a good competitor in the forest, you have to be a small plant. - Queen's University's students made a new research.
Smaller plants may have many advantages over their neighbors.

Q: Read the following article and select the best answer. Article: For many years, artists have flocked to Paris, France, to paint or to learn to paint. Perhaps artists first went there because of the city's beauty. They went to paint pictures of the broad, tree-lined streets, the great churches, and the graceful river bridges. The artists felt comfortable in Paris because the people of the city had always enjoyed art. Paris had great art museums, filled with famous paintings and statues from many countries. And the people of Paris had always welcomed new ideas. In this city, artists felt free to experiment with new ways of painting. As soon as famous artists painted in Paris, students came to learn from them. People came to buy paintings. People called art dealers set up galleries where paintings were bought and sold. Others kept shops that sold artists' paints and supplies. Students and artists who were not yet famous could live in Paris for very little money. They learned by studying great art in the museums, and they learned from one another. They held art fairs, hanging their paintings outdoors along the streets. Today, New York City and Florence, Italy, are also famous art centers. But the world's main art exhibits are still held in Paris. Important judges of art live there. Most of the new ways of painting that have started in the last hundred years began in Paris. So artists and art dealers still go to Paris because it is the world's leading art center. Question: On the whole, this story is about. - the world's most famous art center - how to buy a painting in Paris - the famous art centers of New York and Florence - where to set up galleries
A: the world's most famous art center

(Question)
Read the following article and select the best answer. Article: What was your favorite sport during your childhood? Maybe running around the playground or jumping rope for hours would bring you pleasure. At that time you weren't thinking of health, you were just thinking of entertainment . But in this age of high-tech home equipment, the simple joy of jumping rope has been forgotten. I think rediscovering it probably will give you a total-body exercise. Although considered an excellent form of exercise, jumping rope has never been widely accepted because of two reasons. First, most people consider jumping rope to be an excellent form of cardiovascular exercise, but they also believe that it is simply too difficult. In other words, they don't think they'll be able to continue jumping for the near 20 minutes in order to achieve a beneficial physical effect. Second, many people regard it as a little boring and overly repetitive --not as something fun or enjoyable. _ . Instead of doing the usual two-foot bounce over and over again, players good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double -bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping . Nowadays researchers are discovering that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres to perform equally to each other . In a word, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life. Question: According to the researchers, jumping rope _ . - only prepares the brain for learning - is suitable for students only - helps both brain hemispheres work together - can be dangerous for old people
(Answer)
helps both brain hemispheres work together
