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)

【英語ですみません】最後の12番は何を書いたら良いのでしょうか…? Video C の実験では、aqueous solution にlead(ii) nitrate, aqueous solution にPottasium iodide を入れていました。 2KI (aq)... 続きを読む

With lead (I) nitrate solution. This precipitation reaction produces a bright yellow solid. (point values in parentheses) Part 1: 1. Copy the unbalanced reaction below into your lab notebook. Balance the reaction by adding coefficients. (1) KI (aq) Pb(NO,), (aq) KNO, (aq) Pbl, (s) 2. a) Which trial are you assigned? b) Copy the data table below into your notebook. Watch video A (make sure it's the correct trial!) and collect your data. You may need to pause or rewatch the video, it goes quickly. (1.5) Mass of Empty Beaker (g) Mass of Beaker+ solid Pb(NO,)。(g) Volume of 1.0 M KI (aq) (mL) For the following calculations, show all your work for full credit. 3. What mass of solid Pb(N0,), was added to the beaker? (1) 4. If the solid Pb(NO,), was dissolved in 45 mL of water, what is the molarity of the Pb(NO,)。 solution? (2.5) 5. Which compound is the limiting reactant? (4) 6. What mass of lead (II) iodide (PbL,) should be produced? (2) Part 2: 7. Watch video B (make sure it's the correct trial!) to see the complete reaction and collection of the product. Copy the data table below and record your data. (1) Mass of filter paper (g) Mass of filter paper + dried precipitate (g) 8. What mass of precipitate was collected? Show your work. (1) Calculate the percent yield for the reaction. Show your work. (2) 10. For your trial, which three ions were present in the filtered solution at the end of the reaction? In other words, which three ions are still dissolved at the end of the reaction? Defend/explain your 9. answer. (3) 11. Watch video C - watch both tests for your trial and record your observations. (1) a) Add lead (II) nitrate - b) Add potassium iodide - 12. These tests were conducted to prove the identity of the limiting reactant. Considering your answers to the previous two questions, describe how these tests support the prediction you made in question 5 about which compound is the limiting reactant. (2)
