I assume we are talking here about "Subject to Subject Raising" and "Subject to Object Raising". I am not sure that I should give you a direct answer to an exam question, but I will happily give you the definitions.
We are talking about constructions which semantically are assumed to involve a main clause and a subordinate clause. In raising, a logical argument of the embedded verb (generally the subject) materializes on the surface as a syntactic argument of the main verb (subject in the case of SSR, object in the case of SOR). It does not however get a thematic role from the main verb (this is the essential point).
SSR "tend". "Anna tends to sleep in class." - Anna is the syntactic subject of "tend", but gets its theta role from "sleep".
SOR "believe". "Anna believes John to love Mary." (Actually slightly awkward English, but it illustrates the point) - John is the syntactic object of "believe", but gets its theta role from "love".
