Q: 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: Young married couple Andrew Hinklin and Clara Hinklin née Fields, who were college sweethearts, are well matched: both are unexciting and unmotivated, only wanting to carve out a plain, simple uninteresting life for themselves. Their marriage is not helped by Clara's opinionated mother living with them in their small one bedroom apartment. However, Clara does wish that their life would be a little more exciting as Andrew said on their honeymoon that their married life would be, least of all by Andrew acknowledging their latest wedding anniversary, their fifth. Clara's wish takes an unexpected turn when Andrew, at work, is assigned to show the visiting Mr. Battingcourt Jr. - the younger half of the head of their London office and who is majority shareholder of their accounting firm - a good time while he's in the US. "Batty" as he is affectionately called by his friends is a party animal, and Andrew, who Batty rechristens "Hinky", feels he has to party along all in the name of job security.
Clara feels that she is losing her stable husband Andrew to Hinky the party animal. Feeling he is partly to blame for the Hinklins' marital problems, Batty advises Clara that she can make herself more exciting to Hinky by changing her demeanor and appearance, more like Mercedes Vasquez, a beautiful and exciting woman who Clara could resemble if made up correctly. Clara agrees to Batty's plan to come to one of their parties masquerading as exotic Latina Dolores Alvaradez, to woo Hinky and thus ultimately show him that she can be exotic like he probably now wants. Complications ensue when others find out about Batty's scheme and when Mercedes Vasquez also attends that party leading to a few mistaken identities.
A:
What is the nickname that the visiting man gives to Andrew?
