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)
