Passage: After school, Greg settled into a life of steady productivity, while living on the proceeds of his shares of The Economist. Working in close association with A. H. Bullen, he produced Pastoral Poetry and Pastoral Drama (1906), the first edited version of the account books of Philip Henslowe (1906–8) and the papers of Edward Alleyn. The latter two works provided him with a knowledge of Renaissance theatrical conditions perhaps rivaled only by E. K. Chambers, and this knowledge he applied to the publications of the Malone Society, which he served as general editor between 1906 and 1939. He served as Librarian of Trinity College, 1907–13, resigning after his marriage to his cousin Elizabeth Gaskell. As an independent scholar, Greg produced editions of The Merry Wives of Windsor (1910), Robert Greene's Orlando Furioso and George Peele's The Battle of Alcazar (published together, 1923), and Sir Thomas More (1911). He returned to specific editing with work on Doctor Faustus (1950). Greg also wrote on the material conditions of Renaissance theater and publishing; his work in this regard includes Dramatic Documents from the Elizabethan Playhouses (1931) and English Literary Autographs, 1550–1650 (1932). The Variants in the First Quarto of King Lear (1940) offered a careful examination of this printing. He also wrote hundreds of reviews, including a notably caustic rejection of J. Churton Collins's 1905 Oxford edition of Robert Greene.

Passage: In November 1988, a new development team within Microsoft (which included former Digital Equipment Corporation developers Dave Cutler and Mark Lucovsky) began work on a revamped version of IBM and Microsoft's OS/2 operating system known as "NT OS/2". NT OS/2 was intended to be a secure, multi-user operating system with POSIX compatibility and a modular, portable kernel with preemptive multitasking and support for multiple processor architectures. However, following the successful release of Windows 3.0, the NT development team decided to rework the project to use an extended 32-bit port of the Windows API known as Win32 instead of those of OS/2. Win32 maintained a similar structure to the Windows APIs (allowing existing Windows applications to easily be ported to the platform), but also supported the capabilities of the existing NT kernel. Following its approval by Microsoft's staff, development continued on what was now Windows NT, the first 32-bit version of Windows. However, IBM objected to the changes, and ultimately continued OS/2 development on its own.

Passage: After graduating from the Yale School of Drama, Clarkson was cast in a 1986 Broadway production of The House of Blue Leaves as a replacement in the role of Corrinna Stroller. The following year, she made her feature film debut in Brian De Palma's The Untouchables (1987), portraying Catherine Ness, the wife of US Treasury Prohibition agent Elliott Ness (Kevin Costner). Clarkson stated she was financially struggling during this time and was paying student loans, and that De Palma expanded her role in the film as she originally only had several days' worth of shooting. The next year, she was cast in Clint Eastwood's The Dead Pool (1988), the fifth installment in the Dirty Harry film series. In 1989, she returned to Broadway portraying a Wall Street investment counselor whose brother (played by Kevin Conroy) is diagnosed with AIDS; the play ran from January to March of that year. Clarkson has stated that beginning in the early 1990s, she went through a turbulent period in her career and was unable to find significant work. She had a small role in Jumanji (1995) before being cast in the independent drama High Art (1998), portraying a drug-addicted German actress in New York City. Her performance earned her an Independent Spirit Award nomination for Best Supporting Actress.
 Link Information: Costner began his acting career with Sizzle Beach, U.S.A. (1981). Following a few minor supporting parts, he rose to prominence with his portrayal of Eliot Ness in The Untouchables (1987). This was followed by a successful period in his career with starring roles in No Way Out (1987), Bull Durham (1988), Field of Dreams (1989), Dances with Wolves (1990), for which he won two Academy Awards, JFK (1991),  (1991), The Bodyguard (1992), and A Perfect World (1993). In 1995, Costner starred in and co-produced Waterworld. The most expensive film ever made at the time, it was a box office disappointment (which nonetheless made a small profit) that marked a downturn in his career. His second directorial feature, The Postman, (1997) was another disappointment. He has since starred in some somewhat unsuccessful films including Message in a Bottle (1999), For Love of the Game (1999), Thirteen Days (2000), 3000 Miles to Graceland (2001), Dragonfly (2002), Rumor Has It (2005), The Guardian (2006), Mr. Brooks (2007), 3 Days to Kill (2014), McFarland, USA (2015), Draft Day (2014), and Criminal (2016). Nevertheless, in recent years he has had supporting parts in critically favored films including The Upside of Anger (2005), Man of Steel (2013), Hidden Figures (2016), Molly's Game (2017), and The Art of Racing in the Rain (2019).

On television, Costner portrayed Devil Anse Hatfield in
the miniseries Hatfields & McCoys (2012), winning the Primetime Emmy Award for Outstanding Lead Actor in a Miniseries or a Movie. Since 2018, he stars as John Dutton on drama series Yellowstone. Question: How many films did the actor who played Clarkson husband in her feature film debut star in?
