Explanation:

For the first question: In Romeo and Juliet, when Friar Lawrence first sees Romeo early in the morning, he assumes Romeo spent the night with Rosaline, as Romeo was previously deeply infatuated with her. The other events (running off with Juliet, killing Tybalt, insulting Capulet) happen later in the play.
For the second question: Friar Lawrence notes that Romeo quickly shifted his intense infatuation from Rosaline to Juliet, so he doubts the sincerity and longevity of Romeo's new feelings, fearing it is just a fleeting, impulsive attraction.

Answer:

1. That Romeo has slept with Rosaline.
2. He doubts the sincerity of Romeo's feelings.
