Question: Primary and The Trials of Life are both what?
Context: "Xu Xiake" (88) () is a barracks ship of the Chinese People's Liberation Army Navy (PLAN).  She was constructed by the 433rd Factory of China State Shipbuilding Corporation (CSSC), also known as the Guangzhou Shipyard International (GSI, 广州广船国际股份有限公司).  Built as part of the Project 048 aircraft carrier program, the primary task of "Xu Xiake" is to provide accommodation for staff working on aircraft carrier trials so that staff can remain on station to continue trials the following day, instead of returning to port and going out for the next trial, thus greatly shortening the time required.  The ship is designed to support 2,500 people for three weeks at sea before needing resupply. A seeding trial or marketing trial is a form of marketing, conducted in the name of research, designed to target product sampling towards selected consumers.  In the marketing research field, seeding is the process of allocating marketing to specific customers, or groups of customers, in order to stimulate the internal dynamics of the market, and enhance the diffusion process.  In medicine, seeding trials are clinical trials or research studies in which the primary objective is to introduce the concept of a particular medical intervention—such as a pharmaceutical drug or medical device—to physicians, rather than to test a scientific hypothesis. Community-based clinical trials are clinical trials conducted directly through doctors and clinics rather than academic research facilities.  They are designed to be administered through primary care physicians, community health centers and local outpatient facilities.  In 1986, the Community Consortium held the first such trials in the United States to determine the efficiacy of preventative treatments after the onset of Pneumocystis pneumonia.  The trials give patients access to new medications and keep doctors involved with new developments in research.  However, critics state that drug company payments to doctors for patients enrolled in such studies present a conflict of interest and potential for abuse.  Community-based trials are becoming prevalent in human-testing stage pharmaceutical research. A mock trial is an act or imitation trial.  It is similar to a moot court, but mock trials simulate lower-court trials, while moot court simulates appellate court hearings.  Attorneys preparing for a real trial might use a mock trial consisting of volunteers as role players to test theories or experiment with each other.  Mock trial is also the name of an extracurricular program in which students participate in rehearsed trials to learn about the legal system in a competitive manner.  Interscholastic mock trials take place on all levels including primary school, middle school, high school, college, and law school.  Mock trial is often taught in conjunction with a course in Trial Advocacy or takes place as an after school enrichment activity. The Trials of Life: A Natural History of Behaviour is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 3 October 1990. Primary is a 1960 Direct Cinema documentary film about the 1960 Wisconsin primary election between John F. Kennedy and Hubert Humphrey for the United States Democratic Party nomination for President of the United States. Isaac Eastey. (November 27, 1627 in Freston,England, diedJune 11, 1712 in Topsfield, Massachusetts) was the husband of Mary Eastey, who was executed during the Salem Witch Trials of 1692.  Isaac and Mary were both highly respected members of the Salem Village Church, and the community in general.  Isaac played a significant role in the witch trials, which is often overlooked in history.  Despite being one of the primary reasons for Mary's accusation, he desperately tried to clear his wife's name and put an end to the trials altogether. Vicriviroc, previously named SCH 417690 and SCH-D, is a pyrimidine CCR5 entry inhibitor of HIV-1.  It was developed by the pharmaceutical company Schering-Plough.  Merck decided to not pursue regulatory approval for use in treatment-experienced patients because the drug did not meet primary efficacy endpoints in late stage trials.  Clinical trials continue in patients previously untreated for HIV. Mary Ann Warren was the oldest accuser during the 1692 Salem witch trials, being 18 years old, when the trials began.  She was a servant for John and Elizabeth Proctor.  Renouncing her claims after being threatened to be hanged, she was later arrested for allegedly practicing witchcraft herself, but did not confess.  Her life after the trials is unknown. The Hawaii State Circuit Courts are the trial courts of general jurisdiction in Hawaii.  They are the primary civil and criminal courts of the Hawaii State Judiciary.  The Circuit Courts are the only Hawaii state courts to conduct jury trials. (The District Courts conduct bench trials while the Intermediate Court of Appeals and Supreme Court are appellate courts).
