The problem: Answer a question about this article:
Hydrogen is the only element that has different names for its isotopes in common use today. During the early study of radioactivity, various heavy radioactive isotopes were given their own names, but such names are no longer used, except for deuterium and tritium. The symbols D and T (instead of 2H and 3H) are sometimes used for deuterium and tritium, but the corresponding symbol for protium, P, is already in use for phosphorus and thus is not available for protium. In its nomenclatural guidelines, the International Union of Pure and Applied Chemistry allows any of D, T, 2H, and 3H to be used, although 2H and 3H are preferred.
What are the only two names still used for radioactive isotopes?
****
The answer: deuterium and tritium


The problem: Answer a question about this article:
Sea levels began to rise during the Jurassic, which was probably caused by an increase in seafloor spreading. The formation of new crust beneath the surface displaced ocean waters by as much as 200 m (656 ft) more than today, which flooded coastal areas. Furthermore, Pangaea began to rift into smaller divisions, bringing more land area in contact with the ocean by forming the Tethys Sea. Temperatures continued to increase and began to stabilize. Humidity also increased with the proximity of water, and deserts retreated.
What weather condition increased?
****
The answer: Temperatures

Physically, clothing serves many purposes: it can serve as protection from the elements, and can enhance safety during hazardous activities such as hiking and cooking. It protects the wearer from rough surfaces, rash-causing plants, insect bites, splinters, thorns and prickles by providing a barrier between the skin and the environment. Clothes can insulate against cold or hot conditions. Further, they can provide a hygienic barrier, keeping infectious and toxic materials away from the body. Clothing also provides protection from harmful UV radiation.
What does clothing keep toxic materials away from?
****
The answer: body

Hundreds of movies have been shot or set in part within the city of Santa Monica. One of the oldest exterior shots in Santa Monica is Buster Keaton's Spite Marriage (1929) which shows much of 2nd Street. The comedy It's a Mad, Mad, Mad, Mad World (1963) included several scenes shot in Santa Monica, including those along the California Incline, which led to the movie's treasure spot, "The Big W". The Sylvester Stallone film Rocky III (1982) shows Rocky Balboa and Apollo Creed training to fight Clubber Lang by running on the Santa Monica Beach, and Stallone's Demolition Man (1993) includes Santa Monica settings. Henry Jaglom's indie Someone to Love (1987), the last film in which Orson Welles appeared, takes place in Santa Monica's venerable Mayfair Theatre. Heathers (1989) used Santa Monica's John Adams Middle School for many exterior shots. The Truth About Cats & Dogs (1996) is set entirely in Santa Monica, particularly the Palisades Park area, and features a radio station that resembles KCRW at Santa Monica College. 17 Again (2009) was shot at Samohi. Other films that show significant exterior shots of Santa Monica include Fletch (1985), Species (1995), Get Shorty (1995), and Ocean's Eleven (2001). Richard Rossi's biopic Aimee Semple McPherson opens and closes at the beach in Santa Monica.
