Problem: Background: Holland Smith was born on April 20, 1882 in Hatchechubbee, Alabama to John V. Smith and his wife Cornelia Caroline McTyeire. He received a Bachelor of Science degree from Auburn University (then known as Alabama Polytechnic Institute) in 1901. He had already decided on a military career and had become first sergeant of a cavalry company in the Alabama National Guard. However, he obtained his Bachelor of Laws degree from the University of Alabama in 1903 and practiced law in Montgomery, Alabama for a year.
Context: Returning to the United States in April 1919, Smith's assignments in the next four years included duty at Norfolk, Virginia, study at the Naval War College, Newport, Rhode Island, and service in Washington, D.C., with the War Plans Section of the Office of Naval Operations. There, he was the first Marine officer to serve on the Joint Army-Navy Planning Committee. Leaving Washington in May 1923, he served aboard the battleships Wyoming and Arkansas as Fleet Marine Officer, U.S. Scouting Fleet, until September of that year.  In February 1924, after serving at Marine Corps Headquarters and in the West Indies in connection with joint Army-Navy maneuvers, Smith joined the Marine Brigade on expeditionary duty in Haiti, serving as that unit's Chief of Staff and Officer in Charge of Operations and Training. He returned from that country in August 1925, to serve as chief of staff of the 1st Marine Brigade at Quantico, Virginia, until September 1926, as a student in the Marine Corps School, Quantico, from then until June 1927, and as Post Quartermaster of the Marine Barracks, Philadelphia Navy Yard, from July 1927 to March 1931.  In April 1931, Smith began another tour of sea duty, this time aboard the USS California as Aide to the Commander and Force Marine Officer of the Battle Force, U.S. Fleet. He served in those capacities until June 1933, commanded the Marine Barracks at the Washington Navy Yard from then until January 1935, and served the following two years at San Francisco, California, as chief of staff, Department of the Pacific. From there he was ordered to Marine Corps Headquarters in March 1937, to serve two years as director of the Division of Operations and Training, after which he was Assistant Commandant of the Marine Corps under Major General Thomas Holcomb from April to September 1939.
Question: What rank did he hold while he was in Norfolk?
Answer: first Marine officer to serve on the Joint Army-Navy Planning Committee.

Problem: Background: The Joker is a fictional supervillain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book Batman (April 25, 1940), published by DC Comics. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design, while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman. In his comic book appearances, the Joker is portrayed as a criminal mastermind.
Context: The Joker was one of the few popular villains continuing to appear regularly in Batman comics from the Golden Age into the Silver Age, as the series continued during the rise in popularity of mystery and romance comics. In 1951, Finger wrote an origin story for the Joker in Detective Comics #168, which introduced the characteristic of him formerly being the criminal Red Hood, and his disfigurement the result of a fall into a chemical vat.  By 1954, the Comics Code Authority had been established in response to increasing public disapproval of comic book content. The backlash was inspired by Frederic Wertham, who hypothesized that mass media (especially comic books) was responsible for the rise in juvenile delinquency, violence and homosexuality, particularly in young males. Parents forbade their children from reading comic books, and there were several mass burnings. The Comics Code banned gore, innuendo and excessive violence, stripping Batman of his menace and transforming the Joker into a goofy, thieving trickster without his original homicidal tendencies.  The character appeared less frequently after 1964, when Julius Schwartz (who disliked the Joker) became editor of the Batman comics. The character risked becoming an obscure figure of the preceding era until this goofy prankster version of the character was adapted into the 1966 television series Batman, in which he was played by Cesar Romero. The show's popularity compelled Schwartz to keep the comics in a similar vein. As the show's popularity waned, however, so did that of the Batman comics. After the TV series ended in 1968, the increase in public visibility had not stopped the comic's sales decline; editorial director Carmine Infantino resolved to turn things around, moving stories away from schoolboy-friendly adventures. The Silver Age introduced several of the Joker's defining character traits: lethal joy buzzers, acid-squirting flowers, trick guns, and goofy, elaborate crimes.
