Answer: The right answer is the pencils on her desk lined up perfectly.
Explanation: Just to elaborate a little bit on the answer, it can be added that the fact that the character of Olya had all the pencils lined up in a fautless way indicates that she might be dominating, perfectionist and methodical with herself. In addition, it indicates that she might be territorial, since, as the narrator says, this symbol was "a warning to others not to take one, or else." The symbol suggests, to conclude, that Olya wanted to have control of her surroundings and wanted others to know that.
Talking about "Hamlet", especially act v, we can say that Gertrude has changed from HAPPY TO REMORSEFUL.
Gertrude has changed since Hamlet's violent confrontation with her. It can be seen that she feels remorse because she has played an important role in the events that provoqued Hamlet's psychological instability and Ophelia's death.
