E and,in addition, English, Spanish ,and Italian words are added.

The explaination for the answer A from OG is  the singular has does not agree in number with English, Spanish ,and Italian words; the verb should be the plural  have
不是很理解A的解释～望各位解释～～谢谢！为什么是看后面的成分来确定谓语动词的单复数形式？

A是倒装的
OG的意思是说 has 这个单词和这句话的主语（就是倒装句谓语后面的这些English, Spanish ,and Italian words）单复数不一致
