問題Ⅱ 次の(1)から(3)の文章を読んで、それぞれの問いに対する答えとして最も適当なものを1,2,3,4から一つ選びなさい。(1)あれはいつのころだつた、まだ、数学などに(注1)凝っていいたときだ。ぼくば友人と競争で、ある問題を解いていた。それが解けたときはほんとっに嬉しかった。それで、すぐに友人に電話した。「おい、やった、解けたぞ!」 ぼくは、ほとんど、叫んでいた。  だが、相手はねむそうにいう。  「なにが、解けただ。いま何時だと思っているんだ。午前2時だぞ!」怒った声だった。それを聞いて、①しまったと思った。確かに、ひどい時間に電話をかけたものだ。  「たとえ、友人だ(注2)とはいえ、午前2時に電話をかけるのは、少し非常識だったな。あやまる。ごめん!」 ぼくはすぐあやまった。すると、相手はいった。  「おまえのバカな友人になら、何時に電話をしようと勝手だ。(注3)おれのいいたいのは、(  ②  )ということだ」 そして、ガチャン。そういえば、相手の声は友入の③それではなかった。          (なだいなだ「こころのかたち」による)(注1)凝る:熱中する(注2)~とはいえ:~といっても (注3)おれ:「私」の意昧(男性が使うことが多い)

Questions 21 to 25 are based on the following passage.

Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.

A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining.

In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.

In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.

Many scientists had believed that the lead would stay in soil and snow for a longer period.

The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected.

Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.

The study published in the journal Nature indicates that ()

A.the Clean Air Act has not produced the desired results

B.lead deposits in arctic snow are on the increase

C.lead will stay in soil and snow longer than expected

D.the US is the major source of lead pollution in arctic snow
