• Classroom example: Bite the dust can refer to a situation involving fail, be defeated, or die.
• Story example: A writer may use Bite the dust when describing a situation involving fail, be defeated, or die.
• Exam example: When a sentence contains Bite the dust, choose the meaning “fail, be defeated, or die.”
