However, only 2.5% of water on the Earth 18 not salty. Demand for fresh water has risen sharply in the last 50 years, and it is still riSing. Finding answers to these problems may be one of the biggest challenges of the 21st century. 回 Overuse also puts pressure on water supplies, In the USA, 95% of the country's fresh water comes from underground sources. With so much water being used to grow crops and raise livestock, water levels aredropping rapidly. Once used, those supplies are gone forever. D The fresh water crisis is not limited to poor countries. In fact, rich and poor countries from Asia to Europe to North America are facing shortages. It's a growing problem that could soon affect us all. E Second, pollution is another big problem. Many of the world's great rivers are badly polluted and many people depend on the rivers. Their health is affected by the health of the river. Steps are being taken to clean up some rivers, but it can take many years. E In many poor countries around the world, people already live in crisis. More than one billion people have no access to clean water. That leads to millions of deaths every year. By 2025, about 25 African countries may face severe water shortages.

英文一段落3文目featuring family mealsのfeaturingとはどういう意味でしょうか?? 調べてみたのですが上手く合いそうな訳が出てきませんでした どなたか教えて下さると幸いです。

第4問 次の問い (A.B)に答えよ。 (配点 40) 次の文章はある説明文の一部である。この文章と表を読み, 下の問い(問1~ に入れるのに最も適当なものを、 それぞれ下の0~ A 4)の 33 36 のうちから一つずつ選べ。 Art may reflect the ways people lived. \Researchers have discussed how One study was conducted to art portrays clothing and social settings. determine if this idea could be extended to paintings featuring family meals. The results of this study might help illustrate why certain kinds of foods were painted. (The researchers examined 140 paintings of family meals painted from the years 1500 to 2000. These came from five countries: the United States, France, Germany, Italy, and the Netherlands. The researchers examined each painting for the presence of 91 foods, with absence coded as 0 and presence coded as 1. For example, when one or more onions appeared in a painting, the researchers coded it as 1. Then they calculated the percentage of the paintings from these countries that included each food. Table 1 shows the percentage of paintings with selected foods. The researchers discussed several findings. First, some paintings from these countries included foods the researchers had expected. Shellfish were most common in the Netherlands' (Dutch) paintings, which was anticipated as nearly half of its border touches the sea. Sécopd, some paintings did not include foods the researchers had expected. Shellfish and fish each appeared in less than 12% of the paintings from the United States, France, and Italy although large portions of these countries border oceans or seas. Chicken, a common food, seldom appeared in the paintings. Thipd, some paintings included foods the researchers had not expected. For example, among German paintings, 20% of them included shellfish although only 6% of the country touches the sea. Also, lemons were most common in paintings from the Netherlands, even though they do not grow there naturally. - 18 - (2610-18)
