What does "it" in " that it has an abundance of words " refer to? English or Chinese?

Context:
Thank you for being patient enough to help me stumble along in this short course of Chinese literature. As you say, this literature is older than any in my native "colonized" tongue. What I can say on behalf of English is that it has an abundance of words and, I think, that must make it more available to providing translations. When I look at this English translation of "Encountering Sorrow" and see how carefully a rhyme & rhythm have been maintained... well, that is not small thing.

It refers to English. It has an abundance of words, which allows choosing the best one to ensure good rhyme & rhythm.
