In chapter 10, Baba stands up to the Russian soldier and prevents him from sexually molesting the Afghan woman. Amir watches as Baba risks his life protecting the woman from the Russian soldier, who eventually leaves her alone. One could connect Baba's courage and bravery to Amir's cowardice earlier in the novel. When Amir was in a similar situation, he refused to intervene and save Hassan from Assef, who ended up raping him. Essentially, Amir's cowardice is juxtaposed to Baba's bravery in this scene. One could also connect Kamal's rape and his reaction to Hassan's rape and ensuing trauma. Similar to Hassan, Kamal does not speak much after being raped and stares into space. Later on in the novel, Sohrab's silence after arriving in America connects to both Kamal and Hassan's trauma after being sexually molested. In a text-to-world example, one could connect the refugees' journey from Jalalabad to Peshawar to the plight of many refugees throughout the world fleeing war zones in search of better lives. In America, illegal immigration from Mexico is also a hot button political issue that can connect to the events in chapter 10.

Text to text refers to how you can relate the events to other events in the book.  You have examples of that.  Text to world would be how you can relate the events to real life.  There is hardship and treachery everywhere, as well as bravery.  Text to self would be to connect it to an event in your life.

There are two ways you can connect Chapter 10 text-to-text. Baba's courage in defying the soldier when the truck is stopped relates to an early part of the story when Amir is not fearless and courageous. The catatonic state of the brutal Kamal relates to an earlier part in the text when Kamal terrorizes Hassan. It also relates to a later portion when Amir attempts restitution.
