答えは4.2なのですが、なぜだと思いますか。答えないので明確な理由はわかりません。

第3問 次の問い (A・B)に答えよ。 A 次の問い (問1・問2)のパラグラフ (段落)には,まとまりをよくするために 取り除いた方がよい文が一つある。 取り除く文として最も適当なものを,それぞ れ下線部①~④のうちから一つずつ選べ。 問1 26 There are about 500 volcanoes around the world which have erupted in recorded history and may erupt in the near future. They are called active volcanoes. ① Many of them are located in the Pacific, such as in Japan and Hawaii. ② Under the Pacific Ocean, the earth's plates are moving slowly and colliding, which sometimes causes eruptions. However, not all volcanoes are active. Before a volcano erupts, magma begins to slowly rise from cracks near the surface. Some volcanoes are temporarily inactive and some are "extinct," meaning they will never erupt again.
