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

Q: Who has studied the Mahayana?, Context: There is no evidence that Mahayana ever referred to a separate formal school or sect of Buddhism, but rather that it existed as a certain set of ideals, and later doctrines, for bodhisattvas. Initially it was known as Bodhisattvayana (the "Vehicle of the Bodhisattvas"). Paul Williams has also noted that the Mahayana never had nor ever attempted to have a separate Vinaya or ordination lineage from the early schools of Buddhism, and therefore each bhiksu or bhiksuni adhering to the Mahayana formally belonged to an early school. This continues today with the Dharmaguptaka ordination lineage in East Asia, and the Mulasarvastivada ordination lineage in Tibetan Buddhism. Therefore Mahayana was never a separate rival sect of the early schools. From Chinese monks visiting India, we now know that both Mahayana and non-Mahayana monks in India often lived in the same monasteries side by side.

Q: What did Speilberg want to be the basis for Interstellar?, Context: In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst. In January 2007, screenwriter Jonathan Nolan met with them to discuss adapting Obst and Thorne's treatment into a narrative screenplay. The screenwriter suggested the addition of a "time element" to the treatment's basic idea, which was welcomed by Obst and Thorne. In March of that year, Paramount hired Nolan, as well as scientists from Caltech, forming a workshop to adapt the treatment under the title Interstellar. The following July, Kip Thorne said there was a push by people for him to portray himself in the film. Spielberg later abandoned Interstellar, which was eventually directed by Christopher Nolan.
