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 "Mahayana Buddhism flourished in India from the 5th century CE onwards, during the dynasty of the Guptas. Mahāyāna centres of learning were established, the most important one being the Nālandā University in north-eastern India."?
The answer to this question is:
What era was where the Buddhism flourished?
