Seems to me all they are asking you to do is replace the person with the noun they provide. Looking at the example they give you... I and Dave. All they did was replace I with Dave. For your first problem all you need to do is replace Susan with I. The answer will be Susan speaks French and German. Notice the s ? Speaks, not speak. One more, then you do the rest. " I work with my father." Eddie is going to replace I. Eddie works with his father. Just change the I either the mound they give you. The rest should makes sense. Hope this helps you!
