Which of the following is the most likely reason that ancient peoples sought to identify inflammation?

#Section 2: General Biology

  1. Seeing such signs would be cause for their seeking out a healer in their community.

  2. Presence of the signs of inflammation in a patient could be a condemnation of the healer.

  3. The ancients probably knew of plant derivatives that could reduce the pain of inflammation.

  4. If these signs were present, they would know that healing was taking place; otherwise the patient would likely die.
