Question: Panama's first department stores such as Bazaar Francés, La Dalia and La Villa de Paris started as textile retailers at the turn of the nineteenth century. Later on in the twentieth century these eventually gave way to stores such as Felix B. Maduro, Sarah Panamá, Figali, Danté, Sears, Gran Morrison and smaller ones such as Bon Bini, Cocos, El Lider, Piccolo and Clubman among others. Of these only Felix B. Maduro (usually referred to as Felix by locals) and Danté remain strong. All the others have either folded or declined although Cocos has managed to secure a good position in the market.
Try to answer this question if possible: When did Panama's Department stores first start? 
Answer: at the turn of the nineteenth century
Question: In England, partly in response to a philosophy propounded by the Oxford Movement and others associated with the emerging revival of 'high church' or Anglo-Catholic ideas during the second quarter of the 19th century, neo-Gothic began to become promoted by influential establishment figures as the preferred style for ecclesiastical, civic and institutional architecture. The appeal of this Gothic revival (which after 1837, in Britain, is sometimes termed Victorian Gothic), gradually widened to encompass "low church" as well as "high church" clients. This period of more universal appeal, spanning 1855–1885, is known in Britain as High Victorian Gothic.
Try to answer this question if possible: When was neo-Gothic popularized by influential figures?
Answer: during the second quarter of the 19th century
Question: On April 4, 2008, Beyoncé married Jay Z. She publicly revealed their marriage in a video montage at the listening party for her third studio album, I Am... Sasha Fierce, in Manhattan's Sony Club on October 22, 2008. I Am... Sasha Fierce was released on November 18, 2008 in the United States. The album formally introduces Beyoncé's alter ego Sasha Fierce, conceived during the making of her 2003 single "Crazy in Love", selling 482,000 copies in its first week, debuting atop the Billboard 200, and giving Beyoncé her third consecutive number-one album in the US. The album featured the number-one song "Single Ladies (Put a Ring on It)" and the top-five songs "If I Were a Boy" and "Halo". Achieving the accomplishment of becoming her longest-running Hot 100 single in her career, "Halo"'s success in the US helped Beyoncé attain more top-ten singles on the list than any other woman during the 2000s. It also included the successful "Sweet Dreams", and singles "Diva", "Ego", "Broken-Hearted Girl" and "Video Phone". The music video for "Single Ladies" has been parodied and imitated around the world, spawning the "first major dance craze" of the Internet age according to the Toronto Star. The video has won several awards, including Best Video at the 2009 MTV Europe Music Awards, the 2009 Scottish MOBO Awards, and the 2009 BET Awards. At the 2009 MTV Video Music Awards, the video was nominated for nine awards, ultimately winning three including Video of the Year. Its failure to win the Best Female Video category, which went to American country pop singer Taylor Swift's "You Belong with Me", led to Kanye West interrupting the ceremony and Beyoncé improvising a re-presentation of Swift's award during her own acceptance speech. In March 2009, Beyoncé embarked on the I Am... World Tour, her second headlining worldwide concert tour, consisting of 108 shows, grossing $119.5 million.
Try to answer this question if possible: For which decade, did Beyonce have more top ten songs than any other woman?
Answer: 2000s
Question: Vacuum is useful in a variety of processes and devices. Its first widespread use was in the incandescent light bulb to protect the filament from chemical degradation. The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and vacuum frying. Ultra-high vacuum is used in the study of atomically clean substrates, as only a very good vacuum preserves atomic-scale clean surfaces for a reasonably long time (on the order of minutes to days). High to ultra-high vacuum removes the obstruction of air, allowing particle beams to deposit or remove materials without contamination. This is the principle behind chemical vapor deposition, physical vapor deposition, and dry etching which are essential to the fabrication of semiconductors and optical coatings, and to surface science. The reduction of convection provides the thermal insulation of thermos bottles. Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing which is used in freeze drying, adhesive preparation, distillation, metallurgy, and process purging. The electrical properties of vacuum make electron microscopes and vacuum tubes possible, including cathode ray tubes. The elimination of air friction is useful for flywheel energy storage and ultracentrifuges.
Try to answer this question if possible: What is produced by a vacuum and used in electron beam welding and vacuum frying?
Answer:
chemical inertness
