Question

Which best revises sentence 2 to make it more precise? Watching him bravely tell the truth about what had really happened that day and how he had been the one responsible for the destruction of our neighbor’s award-winning flower garden, I realized that he knew he would likely face unpleasant consequences. I tried to imagine how difficult it must have been for someone so young to do something so courageous and what must have been going through his mind, but all I could think about was the punishment he would probably receive for doing the right thing. Although my brother appeared to be acting bravely, I was certain he was tempted to do the wrong thing that day to avoid some sort of unpleasant punishment, and I thought for a second that he would change his mind at the last moment. My brother’s actions that day were very admirable, and I remember wondering how someone so young could do something like that, and then I wondered if I would do the same thing or something different just to avoid getting into unwanted trouble.

Answer 1

Watching him bravely tell the truth about what had really happened that day and how he had been the one responsible for the destruction of our neighbor’s award-winning flower garden, I realized that he knew he would likely face unpleasant consequences. 
Statement 1 is the most specific and concrete expression of the sentence 2 "I knew that what he did that day must have been extremely difficult for him." It gives us the exact information about what his brother did and why it is a very difficult decision to acknowledge his fault. It means that restoring the award-winning flower garden is not only going to be very costly but would also take a long time to be completed and it may negatively affect the relationship of his family and their neighbor.  

Answer 2

the answer is A.) Watching him bravely tell the truth about what had really happened that day and how he had been the one responsible for the destruction of our neighbor’s award-winning flower garden, I realized that he knew he would likely face unpleasant consequences
