Answer:
Third Option: Anne Frank and her family go into hiding in the cramped attic of a warehouse for two agonizing years to escape the horrors of Nazi occupation in Amsterdam.
Step-by-step explanation:
Objective means something which is tangible, measurable, and concrete. If statement(s) includes something which is based on perceptions, interpretations, emotions opinions etc., it will become subjective.
First statement has many subjective phrases, e.g timeless story, perceptive recounting, living in hiding (with no mention of place). So, it is subjective statement and not objective.
Second option has subjective phrases e.g unusual insight, thoughts and experiences.
Fourth option has subjective phrases e.g thoughts and experiences, living in hiding (with no mention of place).
Third option had no subjective phrases and everything/fact told is objective i.e Anne Frank and her family, cramped attic of a warehouse, for two agonizing years. So, this option is correct as objective summary.
