An internal conflict; the protagonist vs. internalized social forces.
The internal conflict can also develop between the protagonist and herself. However, this is not the case here, as she is struggling to overcome the supposed obstacles that others (her family) are imposing upon her. It's not that she doubts her own capabilities or competence; it's that others doubt her capabilities, based on the fact that she is a woman.
If your choices are the following:
<span>A. I have heard it asserted by some, that as America hath flourished under her former connection with Great Britain that the same connection is necessary towards her future happiness, and will always have the same effect.
B. We may as well assert that because a child has thrived upon milk that it is never to have meat, or that the first twenty years of our lives is to become a precedent for the next twenty.
C. But even this is admitting more than is true, for I answer roundly, that America would have flourished as much, and probably much more, had no European power had any thing to do with her.
D. The commerce, by which she hath enriched herself, are the necessaries of life, and will always have a market while eating is the custom of Europe.
Then the answer is B.</span>
