Question: The Merchandise Mart (or the Merch Mart, or the Mart) is a commercial building located in the downtown Loop, of Chicago, Illinois, United States. When it opened in 1930, it was the largest building in the world, with 4,000,000 square feet (372,000 m2) of floor space. The art deco landmark is located at the junction of the Chicago River's branches. The building is a leading retailing and wholesale destination, hosting 20,000 visitors and tenants per day as of the late 2000s.

Wholesale showrooms occupy 50% of the usable floor space, and the Sultan of Brunei once spent $1.6 million at the Mart to furnish his entire palace, claiming the location was the only place where the task could be completed in one week. Select showrooms are open only to wholesalers, with others accessible to the general public. Unlike stores with traditional shelf and rack displays, entire usable rooms are created, providing consumers an opportunity to compare form and function between applications and manufacturers. A portion of the stores offer items for purchase singly or as a collection, while others offer design services, preservation, renovation, or installation. In addition to being a resource for architects and decorators, the Mart also has featured award-winning designs as selected by the American Institute of Architects. Catering to suppliers, on-site firms specialize in providing professional services for market research projects.  In 1931, Marshall Field and Company lost five million dollars, followed by eight million in 1932. The wholesale division was greatly reduced and Field's reduced its space in the Mart from four floors to one and half. The Mart continued to display the latest trends in home furnishings within the showrooms and trade shows. The company recovered late in the decade, but did not return to all previously occupied space.  In 1942, L. L. Skaggs formed a partnership with three other men and named the partnership the Owners Service Company, hence Osco. The headquarters moved from Waterloo, Iowa, to the Merchandise Mart.  A retail shopping area, named The Shops at the Mart, opened in 1991 and includes apparel shops, beauty services, bookstores and newsstands, financial services, telecommunication services, travel services, specialty food and wine stores, photo services, a dry cleaner, shoe shine stand, and a food court. A U.S. Post Office is located on the first floor and a FedEx location is on the second floor.  The Apparel Center houses the 521-room Holiday Inn Chicago Mart Plaza River North hotel, the offices of the Chicago Sun-Times and the Chicago campus of the Illinois Institute of Art - Chicago, as well as the Chicago office of the Ogilvy & Mather advertising agency. GoHealth occupies 93,000 square feet (8,600 m2) on the 5th floor of Merchandise Mart, the Potbelly Sandwich Works' corporate offices are located in the tower. Motorola Mobility moved its headquarters to the Merchandise Mart in 2014.

Problem: Devika Rani Chaudhuri, usually known as Devika Rani (30 March 1908 - 9 March 1994), was an actress in Indian films who was active during the 1930s and 1940s. Widely acknowledged as the first lady of Indian cinema, Devika Rani had a successful film career that spanned 10 years. Born into a wealthy, anglicized Indian family, Devika Rani was sent to boarding school in England at age nine and grew up in that country. In 1928, she met Himanshu Rai, an Indian film-producer, and married him the following year.

Devika Rani Chaudhuri was born into a Bengali family in Waltair near Visakhapatnam in present-day Andhra Pradesh, into an extremely affluent and educated Bengali family. Her father, Colonel Manmatha Nath Chaudhuri, was the first Indian Surgeon-General of Madras Presidency and a nephew of Rabindranath Tagore.  Her mother, Leela Devi Choudhary, came from an educated family and was a grand-niece of Tagore. Devika's father's brothers were Ashutosh Chaudhuri, Chief Justice of Calcutta High Court, Jogesh Chandra Chaudhuri, a prominent Kolkata-based barrister and Pramatha Chaudhuri, the famous Bengali writer.  Devika Rani was related through both her parents to the poet and Nobel Laureate Rabindranath Tagore. Her father, Manmathnath Choudhary, was the son of Sukumari Devi Choudhary, sister of Rabindranath Tagore. Devika's mother, Leela Devi Chaudhuri, was the daughter of Indumati Devi Chattopadhyay, whose mother Saudamini Devi Gangopadhyay was another sister of the Nobel laureate. Devika's father and maternal grandmothers were first cousins to each other, being the children of two sisters of Rabindranath Tagore.  Further, two of her father's brothers had also married their cousins: Prativa Devi Choudhury, wife of Ashutosh Choudhary, was the daughter of Hemendranath Tagore, and Indira Devi Choudhary, wife of Promatho Choudhary, was the daughter of Satyendranath Tagore. Devika thus had strong ties to Jarasanko, seat of the Tagore family in Kolkata and a major crucible of the Bengali renaissance.  Devika Rani was sent to boarding school in England at the age of nine, and grew up there. After completing her schooling in the mid-1920s, she enrolled in the Royal Academy of Dramatic Art (RADA) and the Royal Academy of Music in London to study acting and music. She also enrolled for courses in architecture, textile and decor design, and even apprenticed under Elizabeth Arden. All of these courses, each of them a few months long, were completed by 1927, and Devika Rani then took up a job in textile design.
