Input: Read this: Martin Luther, a German monk, started the German Reformation by posting 95 theses on the castle church of Wittenberg on October 31, 1517. The immediate provocation spurring this act was Pope Leo X's renewal of the indulgence for the building of the new St. Peter's Basilica in 1514. Luther was challenged to recant his heresy at the Diet of Worms in 1521. When he refused, he was placed under the ban of the Empire by Charles V. Receiving the protection of Frederick the Wise, he was then able to translate the Bible into German.

Input: Read this: Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption. There is little to no structural damage. The most common cause of this type of diarrhea is a cholera toxin that stimulates the secretion of anions, especially chloride ions. Therefore, to maintain a charge balance in the lumen, sodium is carried with it, along with water. In this type of diarrhea intestinal fluid secretion is isotonic with plasma even during fasting. It continues even when there is no oral food intake.
Question: What means there is an increase in structural damage or absorption inhibition?

Output: unanswerable

Input: Read this: Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. Psychological factors such as social support, hypnotic suggestion, excitement, or distraction can significantly affect pain's intensity or unpleasantness. In some arguments put forth in physician-assisted suicide or euthanasia debates, pain has been used as an argument to permit terminally ill patients to end their lives.
