The correct answer that fits the context of the passage is likely "inspire" and "pierce". However, "inspire" may be a typo or misused, as it doesn't seem to fit well with the context of the students reacting to a smell. A more appropriate word might be "inhale".
So the passage with corrected terms might read:
"One by one, the students in the classroom next to the science lab began to look up and inhale deeply at first and then quickly cover their noses. Something was going terribly wrong in the science lab, and the smell was beginning to pierce the other classrooms on the hall."
Please provide the list of answer options to choose the correct one.
