How does the characterization of Caesar in this passage connect to the central idea of the passage?

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 support that the author, uses in the article facing our fears is a): a definition of the part of the brain called the amygdala.

he takes neuroscientist joseph ledoux's words by telling that by falling to distinguish between evolutionary old systems located in the amygdala and newer systems, centered in the prefrontal cortex, doctors have conflated non conscious threat circuits in the brain with circuits that underlie the conscious experience of fear. that, the author says, "leads ledoux to the jarring conclusion that the amygdala, a decades-old centerpiece of the brain's fear circuit, does not underlie the conscious feeling of fear".

despite this, the author points out in the article that that is a controversial notion and that evidence, in animal and humans, supports the idea that core emotions can exist outside of conscious awareness.
