In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: The film is set in 1910; the story beginning by documenting the flooding of the River Seine that year.
Shy projectionist Emile has a passion for film and is in love with his co-worker at the cinema, Maud. His friend, an exuberant inventor and delivery driver, Raoul, picks him up from work to transport him in his bizarre vehicle (called "Catherine"), to obtain a new belt for his projector. In purchasing a new belt, Emile also buys himself a new camera, which is almost stolen by a thief. The story also introduces Lucille, Raoul's childhood friend: a cabaret singer at the club L'Oiseau Rare ("The Rare Bird"), whose aunt Carlotta tries to marry her to the wealthy Police Commissioner, Victor Maynott. One evening, Raoul brings Emile to make a delivery to the Botanical Gardens. In the absence of the Professor who works there, the place is guarded by his assistant, a proboscis monkey named Charles. Here, Raoul experiments with an "Atomize-a-Tune" mixture which temporarily gives Charles the voice of an opera singer and an unstable "super fertilizer" which instantly grows a sunflower seed into a giant sunflower, which topples towards Raoul and Emile. In the ensuing disorder, an explosion occurs when the two chemicals are mixed. Everyone is unscathed, but Emile is convinced he has glimpsed a monstrous creature, a photo of which later appears in the newspapers.
A:
Who did Raoul pick up from work?
