Background: Rosalind Elsie Franklin (25 July 1920 - 16 April 1958) was an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely recognised posthumously. Born to a prominent British Jewish family, Franklin was educated at a private day school at Norland Place in West London, Lindores School for Young Ladies in Sussex, and St Paul's Girls' School, London. Then she studied the Natural Sciences Tripos at Newnham College, Cambridge, from which she graduated in 1941.
Context: Franklin went to Newnham College, Cambridge in 1938 and studied chemistry within the Natural Sciences Tripos. There she met the spectroscopist Bill Price, who worked with her as a laboratory demonstrator and who later became one of her senior colleagues at King's College London. In 1941, she was awarded second-class honours from her final exams. The distinction was accepted as a bachelor's degree in qualifications for employment. Cambridge began awarding titular B.A. and M.A. degrees to women from 1947, and the previous women graduates retroactively received these. In her last year at Cambridge, she met a French refugee Adrienne Weill, a former student of Marie Curie, who had a huge influence on her life and career and helped her to improve her spoken French. Franklin was awarded a research fellowship at Newnham College, with which she joined the physical chemistry laboratory of the University of Cambridge to work under Ronald Norrish, who later won the Nobel Prize in Chemistry. In her one year of work there, she did not have much success. As described by his biographer, Norrish was "obstinate and almost perverse in argument, overbearing and sensitive to criticism". He could not decide for her what to work upon, and at that time was succumbing to heavy drinking. Franklin wrote that he made her despise him completely. Resigning from Norrish's Lab, she fulfilled the requirements of the National Service Acts by working as an assistant research officer at the British Coal Utilisation Research Association (BCURA) in 1942. The BCURA was located on the Coombe Springs Estate near Kingston upon Thames near the southwestern boundary of London. Norrish acted as advisor to the military at BCURA. John G. Bennett was the director. Marcello Pirani and Victor Goldschmidt, both refugees from the Nazis, were consultants and lectured at BCURA while Franklin worked there. During her BCURA research, she stayed at Adrienne Weill's boarding house in Cambridge until her cousin Irene Franklin asked to join her in a vacated house of her uncle in Putney. With Irene, she volunteered as an Air Raid Warden and regularly made patrols to see the welfare of people during air raids. She studied the porosity of coal using helium to determine its density. Through this, she discovered the relationship between the fine constrictions in the pores of coals and the permeability of the porous space. By concluding that substances were expelled in order of molecular size as temperature increased, she helped classify coals and accurately predict their performance for fuel purposes and for production of wartime devices such as gas masks. This work was the basis of her Ph.D. thesis The physical chemistry of solid organic colloids with special reference to coal for which the University of Cambridge University awarded her a Ph.D. in 1945. It was also the basis of several papers.
Question: what did she work on in the laboratory?
Answer: She studied the porosity of coal using helium to determine its density.

Background: The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It also includes one of the richest regular-season rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome.
Context: Since 1952, traditional trail rides have been a part of the Houston Livestock Show and Rodeo. As of 2017, there were 13 official trail rides, totaling over 3,000 riders. The trail rides range in size from a dozen to over one thousand people who ride on horseback or in horse-drawn wagons from various areas of the state to Houston. They make their way at about 3 miles (4.8 km) per hour, covering up to 17 miles (27 km) each day. Many of the routes take place in part along major highways and busy city streets, making safety a major concern. The trail rides last from a few days to three weeks, depending on the distance they cover. Some of the participants are able to join only on weekends or at the end of the trip. The days start very early, and often end with live music or a small celebration. Many riders choose to camp in recreational vehicles rather than in the open. Each morning, they drive their vehicles and horse trailers to the next camping spot, then have a bus or convoy take them back so they can retrace their path on horseback. Participants can bring their own provisions, or, in some cases, purchase meals at a chuck wagon that is also following the trail. The rides converge at Memorial Park in Houston on Go Texan Day, the Friday before the livestock show and rodeo begins. The city closes some roads downtown to allow the riders to reach their destination safely. The resulting traffic interruption cause annual complaints from those who work downtown. The following day, all of the trail riders participate in the parade.
Question: Is the trail ride suitable for children?
Answer:

Background: Alba was born in Pomona, California, to Catherine Louisa (nee Jensen) and Mark David Alba. Her mother has Danish, Welsh, German, English, and French ancestry, while her paternal grandparents, who were born in California, were both the children of Mexican immigrants. She has a younger brother, Joshua. Her third cousin, once removed, is writer Gustavo Arellano.
Context: Alba expressed an interest in acting from the age of five. In 1992, the 11-year-old Alba persuaded her mother to take her to an acting competition in Beverly Hills, where the grand prize was free acting classes. Alba won the grand prize, and took her first acting lessons. An agent signed Alba nine months later. Her first appearance on film was a small role in the 1994 feature Camp Nowhere as Gail. She was originally hired for two weeks but her role turned into a two-month job when one of the prominent actresses dropped out. Alba appeared in two national television commercials for Nintendo and J. C. Penney as a child. She was later featured in several independent films. She branched out into television in 1994 with a recurring role as the vain Jessica in three episodes of the Nickelodeon comedy series The Secret World of Alex Mack. She then performed the role of Maya in the first two seasons of the television series Flipper. Under the tutelage of her lifeguard mother, Alba learned to swim before she could walk, and she was a PADI-certified scuba diver, skills which were put to use on the show, which was filmed in Australia. In 1998, she appeared as Melissa Hauer in a first-season episode of the Steven Bochco crime-drama Brooklyn South, as Leanne in two episodes of Beverly Hills, 90210, and as Layla in an episode of Love Boat: The Next Wave. In 1999, she appeared in the Randy Quaid comedy feature P.U.N.K.S.. After Alba graduated from high school, she studied acting with William H. Macy and his wife, Felicity Huffman, at the Atlantic Theater Company, which was developed by Macy and Pulitzer Prize-winning playwright and film director, David Mamet. Alba rose to greater prominence in Hollywood in 1999 after appearing as a member of a snobby high school clique in the Drew Barrymore romantic comedy Never Been Kissed, and as the female lead in the 1999 comedy-horror film Idle Hands, opposite Devon Sawa.
Question: What other film she had?
Answer:
the female lead in the 1999 comedy-horror film Idle Hands, opposite Devon Sawa.
