Listen to the conversation between a student and a librarian.
Student: Hi, I’m looking for some help with my research paper. I need to find some books on environmental science.
Librarian: Sure! We have a whole section on that. Are you looking for specific topics within environmental science?
Student: Yes, I’m particularly interested in climate change and renewable energy sources.
Librarian: Alright! You can find books in that area on the second floor. Would you like some recommendations?
Student: That would be great, thank you!
Note: This question has been adapted from its original format to accommodate a reading-based version. In the official TOEFL exam, speaking and listening sections require verbal responses and audio prompts, which are not represented here. Please note that this adaptation may not fully reflect the nature or difficulty of the official exam. The audio feature for these sections will be available soon.
