Consider the question. Given the sentence "Korean students are listening to their teacher." can we conclude that "Students are listening to their teachers math course."?
Options:
- yes
- it is not possible to tell
- no
 What is the step-by-step reasoning process to arrive at the answer: it is not possible to tell?
Korean students like many around the world take a variety of school courses besides math and without being told the subject of the course it would be hard to identify it.
