In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: What did those tapped by those in power have to follow?, Context: The Ming court appointed three Princes of Dharma () and five Princes (), and granted many other titles, such as Grand State Tutors () and State Tutors (), to the important schools of Tibetan Buddhism, including the Karma Kagyu, Sakya, and Gelug. According to Wang Jiawei and Nyima Gyaincain, leading officials of these organs were all appointed by the central government and were subject to the rule of law. Yet Van Praag describes the distinct and long-lasting Tibetan law code established by the Phagmodru ruler Tai Situ Changchub Gyaltsen as one of many reforms to revive old Imperial Tibetan traditions.
Example Output: the rule of law

Example Input: What is one example of hydrogen cations?, Context: To avoid the implication of the naked "solvated proton" in solution, acidic aqueous solutions are sometimes considered to contain a less unlikely fictitious species, termed the "hydronium ion" (H3O+). However, even in this case, such solvated hydrogen cations are more realistically conceived as being organized into clusters that form species closer to H9O+4. Other oxonium ions are found when water is in acidic solution with other solvents.
Example Output: hydronium ion

Example Input: A generator that can be activated if the primary generator fails or runs out is described as what kind of power?, Context: The infinitive form ends in t (archaically, ti). It is the form found in dictionaries and the form that follows auxiliary verbs (for example, muzu te slyset"I can hear you"). Czech verbs have three grammatical moods: indicative, imperative and conditional. The imperative mood adds specific endings for each of three person (or number) categories: -/-i/-ej for second-person singular, -te/-ete/-ejte for second-person plural and -me/-eme/-ejme for first-person plural. The conditional mood is formed with a particle after the past-tense verb. This mood indicates possible events, expressed in English as "I would" or "I wish".
Example Output:
auxiliary
