Internal conflict is the point at which a character has to decide to admit to themselves what the issue going on in their head is and to take some sort of action on it. For some characters such as Dante (Dante's Inferno), this is dealing with depression and seeing the things that await him in Hell if he commits suicide. For others, it's working an issue that is a part of their past, such as PTSD flashbacks from war.
I'm not entirely sure how to say where in a story this conflict takes place, as it varies from piece to piece. Hopefully, however, this provides some better understanding of the concept.
The correct answer is "Brutus decides to join the conspiracy against Caesar because he fears that Caesar will become ruthless once he has absolute power.

Explanation: The central idea of the passage is that Brutus has no doubt that Caesar will be crowned king, but he doubts that Caesar will not be corrupted once he is given power, and by this he plans to assassinate him before he rises to power, as he puts “kill him in the shell” (II.i.33–34).
The correct answer is the use of black-and-white shadow puppetry in the Balinese production of The Tempest puts more emphasis on the dialogue than on the actors.
