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

Who has studied the Mahayana?, Context: There is no evidence that Mahāyāna 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 Bodhisattvayāna (the "Vehicle of the Bodhisattvas"). Paul Williams has also noted that the Mahāyāna never had nor ever attempted to have a separate Vinaya or ordination lineage from the early schools of Buddhism, and therefore each bhikṣu or bhikṣuṇī adhering to the Mahāyāna formally belonged to an early school. This continues today with the Dharmaguptaka ordination lineage in East Asia, and the Mūlasarvāstivāda ordination lineage in Tibetan Buddhism. Therefore Mahāyāna was never a separate rival sect of the early schools. From Chinese monks visiting India, we now know that both Mahāyāna and non-Mahāyāna monks in India often lived in the same monasteries side by side.

What does research show about sexual orientation?, Context: Scientists do not know the exact cause of sexual orientation, but they believe that it is caused by a complex interplay of genetic, hormonal, and environmental influences. They favor biologically-based theories, which point to genetic factors, the early uterine environment, both, or the inclusion of genetic and social factors. There is no substantive evidence which suggests parenting or early childhood experiences play a role when it comes to sexual orientation. Research over several decades has demonstrated that sexual orientation ranges along a continuum, from exclusive attraction to the opposite sex to exclusive attraction to the same sex.

Who filed a lawsuit in the same month as Independence Day?, Context: Political interest groups have stated that these laws remove important restrictions on governmental authority, and are a dangerous encroachment on civil liberties, possible unconstitutional violations of the Fourth Amendment. On 30 July 2003, the American Civil Liberties Union (ACLU) filed the first legal challenge against Section 215 of the Patriot Act, claiming that it allows the FBI to violate a citizen's First Amendment rights, Fourth Amendment rights, and right to due process, by granting the government the right to search a person's business, bookstore, and library records in a terrorist investigation, without disclosing to the individual that records were being searched. Also, governing bodies in a number of communities have passed symbolic resolutions against the act.
