🧩 1. The assistant finished her report…
Structural reason:
A noun (“report”) follows → possessive adjective needed.
Meaning logic:
The report belongs to the assistant.
Rhetorical effect:

• hers → possessive pronoun (cannot come before a noun)
Exam note:
Her/hers confusion is very common in IELTS and YDS.

Structural reason:
Non-human possession → its (possessive adjective).
Meaning logic:
The battery belongs to the device.

Why others fail:
• it → subject pronoun
• itself → reflexive, wrong meaning
Exam note:
Its vs it’s is one of the most tested traps in TOEFL/YDS.
