tood wonal algo al dal 目標解答時間: 7分 問1 You are an editor at a school English blog. Andrea, an exchange student from the US, has written an article for the blog. Studies show that children's physical and mental health, as well as their academic performance, improves through healthy school lunches. Experts say that school to learn lunches are a chance for children to enjoy a wide variety of dishes, and about the food history and culture of their nation and the world. In that sense, the lunchroom is also a classroom. Yet, both American and Chinese students waste large amounts of lunch food. Why is that? The following survey results may hint at one possible answer. estra ▸▸Less than half of American schoolchildren rate their meals as tasty enough to eat. This is higher than in Beijing in China, where children are less satisfied with their meals. ▸▸A large majority of schoolchildren in France, followed very closely by South Korea say they are satisfied with their school lunch, and lunch waste in both these countries is not much. Students in both countries look forward to their school meals. The United States Department of Agriculture (USDA) manages public school lunches (in America. The USDA requires school lunches to include plenty of vegetables and fruits, whole grains, milk and at least one meat item or another food item as nutritious as meat. The USDA lunch program in 2020 cost about US$10 billion. provided Despite USDA's efforts, it seems American children are not happy with the school meals they get since the lunch waste level is so high. However, we shouldn't waste food. On the other hand, since coming to Japan, I've learned Japanese students try not to waste food because they have been taught its value. The lunchroom works well as a classroom. 共通テストトリル /10 リーディング 改訂第5版 In terms of lunch satisfaction, which shows the countries' ranking from highest to lowest?
