hello:) for source based case study questions , do I have to compare the content of sources or both the content and purpose?

Compare the content of the sources first then for the highest level, compare the purpose. Do both only if you have time. But I'd suggest to focus on writing a good 2 paragraph based on the content using PEEL first before moving on to the purpose.

Explanation:

Source based questions vary and sometimes the highest level is not always based on the purpose of the author. Look at the provenance of the source and determine who's point of view the source is written from, the tone, and purpose of the source before attempting the highest level.
