Giải đáp câu hỏi và bài tập
A. Read the article. What's another title for this article?
a. Feeding the World b. Bad Bacteria c. Growing Food Slowly
When most people think of bacteria, they think they are bad—and they often are. However, in 2014, three high school students from Ireland found a new, good way to use bacteria to help grow more food. The three girls— Ciara Judge, Emer Hickey, and Sophie Healy Thow—are interested in how science can help feed the Earth's growing population.
One day, Hickey’s mother was in her garden, and noticed something on the roots of her pea plants. The girls learned that pea plants have lumps on their roots containing a kind of bacteria called Diazotroph. The Diazotroph bacteria help the peas grow faster. So, the girls decided to test it with other kinds of plants.
As an experiment, they added the bacteria to barley seeds. They repeated the experiment many times, and found the plants started growing in half as much time, and produced up to 30% more food than normal plants.
The girls are going to continue their research to see if the bacteria can also help other kinds of food plants. They say they take “a great interest in how the world works and how we can help those around us.”
