Input: Consider Input: Passage: Mach argued that, in effect, the water experiment in an otherwise empty universe would remain flat. But if another object were introduced into this universe, perhaps a distant star, there would now be something relative to which the bucket could be seen as rotating. The water inside the bucket could possibly have a slight curve. To account for the curve that we observe, an increase in the number of objects in the universe also increases the curvature in the water. Mach argued that the momentum of an object, whether angular or linear, exists as a result of the sum of the effects of other objects in the universe (Mach's Principle). Question: Mach argued that the momentum of an object exists as a result of the sum of the effects of what?

Output: effects of other objects in the universe

Input: Consider Input: Passage: Droney's health was poor and Kerry had decided to run for his position in the 1978 election should Droney drop out. However, Droney was re-elected and his health improved; he went on to re-assume many of the duties that he had delegated to Kerry. Kerry thus decided to leave, departing in 1979 with assistant DA Roanne Sragow to set up their own law firm. Kerry also worked as a commentator for WCVB-TV and co-founded a bakery, Kilvert & Forbes Ltd., with businessman and former Kennedy aide K. Dun Gifford. Question: Who left the DA's office with Kerry?

Input: Consider Input: Passage: Some important texts were created and studied by scholars. Philosophical works written by Yang Xiong (53 BC 18 AD), Huan Tan (43 BC 28 AD), Wang Chong (27100 AD), and Wang Fu (78163 AD) questioned whether human nature was innately good or evil and posed challenges to Dong's universal order. The Records of the Grand Historian by Sima Tan (d. 110 BC) and his son Sima Qian (14586 BC) established the standard model for all of imperial China's Standard Histories, such as the Book of Han written by Ban Biao (354 AD), his son Ban Gu (3292 AD), and his daughter Ban Zhao (45116 AD). There were dictionaries such as the Shuowen Jiezi by Xu Shen (c. 58 c. 147 AD) and the Fangyan by Yang Xiong. Biographies on important figures were written by various gentrymen. Han dynasty poetry was dominated by the fu genre, which achieved its greatest prominence during the reign of Emperor Wu. Question: What was the name of Ban Biao's female offspring?
Output: Ban Zhao
