The answer to the question 'changes in ?' from the view of the Predictable guideline is 'context'. I think this is wrong and should be 'content'.

A change of context includes changes of content, but the inverse isn't necessarily true. Check out this snippet from the definition of "changes of context" in w3.org's WCAG documentation:
Note: A change of content is not always a change of context. Changes in content, such as an expanding outline, dynamic menu, or a tab control do not necessarily change the context, unless they also change one of the above (e.g., focus).
Take an expanding outline as an example. If a user focuses on the outline then new content appears. However, as long as the user's focus isn't changed to a new item when this happens, the context remains the same. If when the menu expands the focus is shifted to the new content, then this qualifies as change of context.
I hope this helps! The nuances here are a bit tricky. If you want to dig in to it a bit further I'd recommend reading through w3.org's documentation on the Predictable guideline of WCAG. You can find their definition for "changes of context" in the "key terms" section of this page.
