I often have problems with article words referencing to its correct referent. In the following statement for example:
The touching scenes in the film leaves the audience a heavy feeling, encouraging them to consider charitable acts and the role it plays in our society.
My intention is to have the word "them" linked to the audience, and the word "it" linked to the charitable acts.
I am quite confident that the word "them" does link to the audience. But I am worry that the word "it" may not link to the charitable acts. I find that there is possibility the reader may confuse "it" referring to the touching scenes in the film instead of the charitable acts.
Are the article words in the sentence that I have constructed above correctly linked to its referents?
In general, is there a rule to watch out when identifying references in long and complex sentences?
