Read the following passage and answer the question. Last semester, our university opened a small café in the library to help students stay focused while studying. The café serves coffee, tea, and simple snacks at low prices, and students can pay with their campus cards. According to a recent survey, most students believe the café has made their study time more comfortable, especially during exam weeks when they spend long hours in the library. However, some students have complained that the smell of coffee can be distracting, and a few teachers worry that students may chat too much around the tables. The university has responded by setting up a quiet zone on the far side of the library, where no food or drinks are allowed. Overall, the café has become a popular spot, and the university plans to extend its opening hours next term. What is the main idea of the passage? A. The library café has been well received, though it has raised some small concerns. B. Most teachers oppose the library café because students chat too much. C. Students must not bring food or drinks into the library. D. The university will close the café because of the noise complaints.
