The answers are: Romeo killed Tybalt instead of Tybalt killing him. Romeo is banished. Juliet is alive. Friar Lawrence calms and reassures Romeo that he has every reason not to do anything unreasonable or complain about his situation. The events could have had a much worse outcome. Both Romeo and Juliet are alive and love each other, which is all that matters. The answer "Romeo still has his wits about him" isn't correct because he actually lost his sense for a while, as Friar Lawrence reiterates multiple times in the section.
