我知道其中A的错误之一是说时间先后搞反了，但是OG还说了A一个错误，In A, the phrase Being a United States citizen since 1988 and born in Calcutta in 1940 violates parallelism。为什么说这两个短语违反了平行。是因为一个是现在分词短语，一个是过去分词短语吗？ 但是我记得有一个这样的SC题目：

l1．The growth of the railroads led to the abolition of local times, which was determined by when the sun reached the observer's meridian and differing from city to city, and to the establishment of regional times.
（A）which was determined by when the sun reached the observer's meridian and differing
（B）which was determined by when the sun reached the observer's meridian and which differed
（C）which were determined by when the sun reached the observer's meridian and differing
（D）determined by when the sun reached the observer's meridian and differed
（E）determined by when the sun reached the observer's meridian and differing
答案是E，也是过去分词短语和现在分词短语并列呀。
