Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
The only way to answer this question is by reading the text, which unfortunately, I don't have access to. So, you will need to do this in order to be able to answer the question efficiently. In doing this reading, you should identify the ways that George Zenova's desires and interests are different from Ivan Gratz's desires and interests. It is likely that these desires and interests of the two characters are related to the same element, but what each one of them wants to do with the element is different and this must be identified through reading.
