Answer:
Clinton uses the expression "glass ceiling" showing that we are prevented from following our dreams for fear of judgment and failure, but sooner or later this glass ceiling will be broken, freeing us from these limitations and allowing us to make our dreams come true.
Explanation:
Diction refers to the choice of words that an author uses as the main vehicle of the message intended by the text. In the case of the excerpt from Clinton's text, shown in the question above, we can see that the use of the pronoun "we" promotes the objective of communicating directly with the public and of being included in this message, causing identification between the public and the author. Then he uses the expression "glass ceiling" which is used to describe a person's flaws and errors and which should be judged on the basis of that, to describe a limitation that prevents us from conquering our dreams. Accordingly, Clinton says that we have not yet defeated our fear of failures and judgments that limit us to be successful, but that one day we will all break that glass ceiling and we will all be able to follow and fulfill our dreams.
