Input: Consider Input: Question: What are the symptoms of Castleman's disease? Passage:Herpesviruses are a third group of common cancer-causing viruses. Two types of herpesviruses have been associated with cancer: the EpsteinBarr virus (EBV) and human herpesvirus 8 (HHV-8). EBV appears to cause all nonkeratinizing nasopharyngeal carcinomas and some cases of lymphoma, including Burkitt's lymphomathe association is especially strong in Africaand Hodgkin's disease. EBV has also been found in a variety of other types of cancer cells, although its role in causing these other cancers is not well established. KSHV/HHV-8 causes all cases of Kaposi's sarcoma, and has been found in some cases of a cancer-related condition called Castleman's disease. Studies involving other kinds of cancer, particularly prostate cancer, have been inconsistent. Both of these herpesviruses are commonly found in cancerous cells of primary effusion lymphoma. Herpesviruses also cause cancer in animals, especially leukemias and lymphomas.

Output: KSHV/HHV-8 causes all cases of Kaposi's sarcoma, and has been found in some cases of a cancer-related condition called Castleman's disease

Input: Consider Input: Question: Who is the latest person to hold the position of the person Heder persuaded to borrow 40 silver denari? Passage:Between 1150 and 1158, Heder held the dignity of Judge royal, the second-highest secular position after the Palatine. In this capacity, he persuaded Raphael, the abbot of Pannonhalma to borrow 40 silver denari to the king, who planned to visit Henry II, Duke of Austria with his court and a large number of escorts. Raphael had to sell a church estate in order to obtain sum. When Geza invaded the Byzantine Empire and laid siege to Branicevo in late 1154, plausibly Heder and his brother also participated in the campaign alongside other German knights, as Greek historian John Kinnamos referred to them "Saxon" mercenaries. In fear of being seized and executed by King Geza II, his brother, the rebellious Duke Stephen sought refuge in the Holy Roman Empire in the summer of 1157. Frederick I, Holy Roman Emperor, was willing to arbitrate the conflict between Geza II and Stephen, and dispatched his envoys to Hungary. In response, Geza sent delegates to the Emperor, Judge royal Heder and Gervasius, Bishop of Gyor. At the Diet of Regensburg in January 1158, Heder and Gervasius rejected the accusations of Stephen and successfully reached the Emperor withdrew his support from the pretender. After that Stephen left for Constantinople.
Output: In this capacity, he persuaded Raphael, the abbot of Pannonhalma to borrow 40 silver denari to the king, who planned to visit Henry II, Duke of Austria with his court and a large number of escorts
