The industrial pollutants known as were first manufactured in 1929 and were used as coolants for electrical equipment in Europe and North America the 19705, when studies showed that the compounds had entered the food chain and were harmful to some animals. A

A. that the compounds had entered the food chain and were harmful to some animals 由此可见同主语时主谓宾和主系表是可以平行的？

B. the compounds to have entered the food chain and be harmful to some animals be前需加to，因为前面是现在完成时的不定式，所以后面也必须要是不定式？

C. the entry of the compounds into the food chain as harmful to some animals as改成to be，as做连词不能只加单个的形容词

D. the entry of the compounds into the food chain and its harmfulness to animals its不对，harmfulness很笨拙

E. the compounds entering into the food chain and harming some animals into多余，这句子说得好像研究和研究的结果一起发生似的
