Her fear that their promises wont last im pretty sure but if you want and exact translation look it up and write the question from the play and put english translation it helped me alot when i took that course too!
The correct answer is A i think
The correct choice is clouds in this case, because those have the closest connotation in literature with change. The elements given have several connotations in literature. For example, darkness implies that something is unknown or it refers to a sense of being lost. Pesonification is a means of adding emotion and differing points of view to a story. The moon and the night that are treated there have similar connotations to darkness; the moon can also be said to wane or be a full moon so it encompasses change. HOWEVER, the most obvious choice is that clouds mean change; they always drift along and they change, appearing and disappearing.
You ask yourself, "what is the main idea?" "what is the story about?". The theme is like the things that the story surrounds.
