Which sentence describes motivations that causes internal conflict

Realizing that the world is filled with strangers.

Explanation:

In the poem "Second Estrangement", the poet presents the image of an innocent child who realizes that the world is filled with strangers. She says that one does not realize how scary and estrange the world is until he/she is lost and all alone.Through the lines "only to see the face  look strangely down, utterly  foreign, utterly not the one  who loves you", the poet presents the idea of seeing the reality of life. Just like the child, everyone of us think we are in a safe place until we see the reality of life.Then she ends the poem with the lines "How far the world you knew, & tall,  & filled, finally, with strangers."  to ironically bring the message of life's cruelty and reality.
