🧩 1. The supervisor thanked them for their detailed report.
Structural reason:
The verb “thank” requires an object pronoun → them.
Meaning logic:
The students receive the action.
Rhetorical effect:

• they → subject form
• their → possessive adjective
Exam note:
Subject–object pronoun confusion is one of the most frequent YDS traps.
🧩 2. This is not my experiment; it belongs to another group.
Structural reason:
A noun (“experiment”) follows → possessive adjective my.
Meaning logic:
Shows ownership before a noun.
Rhetorical effect:
Academic responsibility distinction.
Why others fail:
• mine → possessive pronoun (no noun allowed after)
• me → object pronoun
Exam note:
My/mine contrasts appear often in IELTS speaking and writing.
