Twenty-six fifth-graders from George Bancroft Elementary School, in Washington, D.C., went to the White House on Friday. They used shovels, rakes and wheelbarrows to help First Lady Michelle Obama break ground on a new vegetable garden. This White House garden is the first since World War II. In the 1940s, First lady Eleanor Roosevelt planted a White House "Victory Garden" to encourage Americans to grow gardens at home. Mrs. Obama's new garden is an L-shaped patch near the fountain on the South Lawn. Vegetables to be planted include lettuce, peas, collard greens, onions and spinach. A herb garden will grow garlic, sage and cilantro. These herbs are used in Mexican food, an Obama family favourite. White House chefs will prepare meals for the First Family with food from the garden and some of the produce will be donated to Miriam's Kitchen, a soup kitchen near the White House. Health food is important to Mrs. Obama. She said that the purpose of the garden is to make sure that her family, the White House staff, and guests eat fresh vegetables. Mrs. Obama has also said that she hopes the new White House garden will help educate Americans about the importance of fresh, nutritious food at a time when obesity is a national crisis. A diet high in natural, unprocessed foods helps people maintain a healthy weight. Mrs. Obama said she has found that her daughters, Malia, 16, and Sasha, 13, like vegetables more if they have been involved in growing them. "If they have been involved in planting and picking the vegetables, they are much more curious about giving them a try," she said. When Bancroft students go back to the White House this summer they will get to taste the vegetables they helped to grow. After they help to harvest the crops, they will cook them in the White House kitchen and then eat them. Question: Why did Mrs. Obama plan to plant the garden? Options: A: Because she wanted her children to become gardeners. B: Because she wanted to know what gardening is like. C: Because she wanted to become a second Eleanor Roosevelt. D: Because she wanted people in the white house to eat a healthy food.
