【正确答案】 A

【答案解析】The information following the first blank helps to define the word that should go in the blank. People who indulge in wild behavior could lead either chaotic or boisterous lives. Temperate and moderate do not describe such people, so eliminate answer choices B and C. Now look at the second blank, which should be filled with a word that has a meaning similar to wild. Neither leisurely nor unpretentious will work in the second blank, so eliminate answer choices D and E.
