passage for each answer.

What is the important feature owned by the modern engine since the 19th century?

选项

答案petrol—fueled internal combustion

解析 19世纪以来,现代引擎的重要特征是什么?答案应该是一个名词性的特征。通过题干关键词since the 19th century定位于第1段第2句1806这个时间词。这一句提到,1806年第一批由内燃发动机驱动的汽车应运而生,于1885年开拓了广泛使用现代汽油内燃机的先河。其中“1806”“1885”替换了题干中的19世纪,modem重现。因此,本题的答案为petrol—fueled internal combustion。
