I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In Hinduism the spiritual teacher is known as a guru, and, in many traditions of Hinduism - especially those common in the West - the emphasis on spiritual mentorship is extremely high, with gurus often exercising a great deal of control over the lives of their disciples."? 

What do gurus call their students?
