In one of his first letters to his Uncle, Robin writes, "They have a list of about 100 rules about email. We can't say this - we can't say that - all about security...No real problem because we don't know anything." Based on this quote, what is Robin's feeling about his experience so far?

He is angry that he has to follow so many rules in the war.

He is confused about why they have so many rules and so little information.

He is frightened by how different everything is outside of the United States.

He regrets joining the military and wants to go home.

In option A, you see the word 'security'. that suggests 'Robin' is referring to the war; you can see Robin uses sarcasm; he said" because we don't know any thing"; this suggests his anger because in human expression we usually use sarcasm to express displeasure; take an example your younger sister came to you and ask you if she could eat all the food; you reply: go ahead because I have no mouth. That means you don't approve of what she is about doing.

So we can take a cue from this and select option 'A'
