Highlight Correct Summary questions account for an insignificant amount of points in the Listening Section, so they deserve a very low priority in preparation for PTE.
The key to this question type is to understand the audio as a whole, so never get distracted, like reading the question. And the given options differ in main meaning, not trivial details.
Highlight Correct Summary questions account for an insignificant amount of points in the Listening Section, so finish them as quick as possible, leaving more time to more worthy WFD.
