Question: Which network ran the shows "Get the Picture" and "Welcome Freshman?"

Context paragraphs:
Welcome Freshmen: Welcome Freshmen is an American comedy that ran on Nickelodeon from 1991 to 1993 with reruns until 1996.  The show took place at Hawthorne High School with a group of high school students and a bumbling vice principal.  Game shows like "Get the Picture" and "Nick Arcade" had celebrity episodes starring some of the cast of "Welcome Freshmen" and "Clarissa Explains It All".

One to Grow On: One to Grow On is an educational public service announcement (PSA) that broadcast during NBC's Saturday morning line-up from 1983 to 1989, when the network ran cartoons.  The name is taken from the custom of putting an extra candle on a birthday cake as "one to grow on".  "One to Grow On" focused on ethical and personal safety dilemmas and attempts to teach viewers how to solve them.  The PSA appeared immediately after the end credits of an NBC cartoon, such as ABC did with "Schoolhouse Rock! " and CBS with "In the News".

Crimson Key Society: The Crimson Key Society is the premier organization at Harvard University devoted to serving the University.  Founded on April 14, 1948, CKS was originally formed to welcome visiting athletic teams to Harvard and represented Harvard's first organized commitment to hospitality.  Crimson Key later went on to provide campus tours to prospective students and visitors, welcome incoming students during Freshman Week, and toured the country to recruit applicants.  CKS has played a major role in expanding Harvard's global image, helping to gain world renown for the university as both an academic institution and as a brand.  Benazir Bhutto, Radcliffe Class of 1973, was perhaps the best-known member of the Society.  Today, CKS continues to provide tours to visitors to the university and welcomes new freshmen with a week of activities, including most famously a Rocky Horror Picture Show-style screening of Love Story that has attracted both praise and criticism from the media.

Karl Brill: Karl Brill was an American football player.  He played at the tackle position for the Harvard Crimson football team in 1904 and 1905 and was selected as a first-team All-American in 1905.  As a sophomore in December 1905, Brill announced that he would not continue playing football.  He said, "I came to Harvard to get a degree as a mining engineer.  For the last two years 'Varsity football has played havoc with my studies.  Already I have been forced to drop work in my freshman and sophomore years.  If I play football again it means that I shall fail to get my degree in four years, and I cannot afford a fifth.  It's either play football and fail to get a degree or abandon the gridiron and get a degree."  In addition to the toll the game had taken on his studies, Bill denounced football on moral grounds, stating that the human body was not mean to withstand the strain that football demands and adding, "I don't believe the game is right.  I dislike it on moral grounds.  It is a mere gladiatorial combat.  It is brutal throughout."

Link Crew: Link Crew is a leadership program offered to high schools in the United States and Canada.  The program allows the school to choose upper-classmen, including Seniors and Juniors to be linked with Freshmen throughout the year.  The Link Leaders help the freshman get involved by informing them about the activities put on by the school and local communities.  These students also help to bridge the gap between freshmen and the rest of the school, when the younger students may feel like they don't belong.  The leaders are a positive role model for the freshman students during the important transition from middle school to high school.  These Link Leaders begin before the school year with two days of extensive training.  Each freshman student is assigned to a group of 10-12 other freshmen and one or two Link Leaders.  Link Leaders have activities during their freshman orientation to make the freshmen feel at home.  Link Leaders continue to support their student Crew by meeting with them weekly, inviting them to school functions, and assisting them academically.

Cambridge Ring (computer network): The Cambridge Ring was an experimental local area network architecture developed at the Computer Laboratory, University of Cambridge starting in 1974 and continuing into the 1980s.  It was a ring network with a theoretical limit of 255 nodes (though such a large number would have badly affected performance), around which cycled a fixed number of packets.  Free packets would be "loaded" with data by a machine wishing to send, marked as received by the destination machine, and "unloaded" on return to the sender; thus in principle there could be as many simultaneous senders as packets.  The network ran over twin twisted-pair cabling (plus a fibre-optic section).

Welcome Back (Mase song): "Welcome Back" is a song by American rapper Mase.  It was released as the first single off his third studio album "Welcome Back".  It's the first single that Mase released in five years since 1999's "Get Ready".  The song was produced by The Movement (Corron Cole, James Bunton) and samples "Welcome Back", the theme from the TV show "Welcome Back, Kotter" by John Sebastian.  Welcome Back is a Hip hop song with a bit of R&B in it.

Media Network: Media Network was the name of a weekly radio programme broadcast on Radio Netherlands Worldwide from 7 May 1981 until 26 October 2000.  When the programme began the station was known as Radio Nederland, but was renamed Radio Netherlands shortly thereafter.  The programme concentrated on communications topics with particular reference to international shortwave broadcasting, but also went on to cover mediumwave and longwave, television, satellite, internet, reviews of shortwave receivers and other electronic devices.  It was produced and presented by Jonathan Marks.  In the course of 1994, he was joined by colleague Diana Janssen, who was working as a media researcher at the station, who co-hosted the show until shortly before its end.  Media Network ran for over 1000 editions.

Placement exam: In many countries, including the United States, it is not unusual for students to take a placement exam in a subject such as mathematics upon entering middle or high school to determine what level of classes they should take.  Typically, students are then placed on a tracking system determined by the class they are approved to enter - for example, if a student takes music theory to students whose knowledge in that area is more advanced than what a typical entering freshman's would be in those subjects.  Scores on such exams as the Advanced Placement, International Baccalaureate, SAT Subject Tests, and British Advanced Level exams can also serve as placement tests for students in certain subjects, where a high score would enable them to get into a more advanced class than what a freshman would normally take.

Get the Picture (game show): Get the Picture is an American children's game show that aired from March 18, 1991 to December 6, 1991 on Nickelodeon.
