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.

Passage: For the third time, the evil Wishmaster returns to wreck the lives of more innocents. This time, his victim is a beautiful, innocent and studious teenage girl named Diana Collins who accidentally opened up the Djinn's tomb (a strange box with a jewel inside) and released him. After gaining his freedom, the Djinn is asked by Professor Barash to let him be the one who makes the wishes. The professor wishes for two of the world's loveliest ladies to be in love with him.
However, as soon as the Djinn grants this wish, the women kill the professor; the Djinn takes the face off of the dead professor and is able to steal his identity. He then kills a secretary by her wishing for "files to burn up" but instead of the files, she burns. He takes the student file of Diana in an effort to find her and force her to fulfill her three wishes. While Diana is on the run, she must endeavor to prevent the Djinn from subjecting the entire world to Hell's wrath. While in a Church thinking it was safe, the Djinn is there instead of the priest. Her friend Ann, who is now the "professor's Teaching Assistant" makes the wish of "wanting to lose a little weight", to which she pukes up her guts in pain. Diana uses her first wish for her to stop having pain, but of course to the Djinn that means killing Ann.
Who is the professor that's friends with the girl who release the Djinn?
