Input: Consider Input: Passage: Booking Holdings and Expedia Group, both online travel agencies, are the largest travel agencies on the list of top earning travel companies. Travel agencies can be multinational companies, referred to as "multiples" in the United Kingdom. They can also be medium-sized organizations, referred to as "miniples" in the United Kingdom, or can be independent, small companies. They can be structured as a limited liability company, a sole proprietorship, or can be set up as a host, franchising, or consortium structure, such as in the case of CWT. A traditional travel agent may work for a travel agency or work freelance. Helloworld Travel is an example of a franchised travel agency, giving agents access to internal systems for product and bookings. While most point-to-point travel is now booked online, traditional agents specialize in niche markets such as corporate travel, luxury travel, cruises, complicated and important trips, and specialty trips. Other niche markets include travelers with disabilities, travelers over the age of 60, women traveling alone, LGBT tourism, the needs of residents in an upmarket commuter town or suburb, or a particular group interested in a similar activity, such as a sport. Examples include StudentUniverse and STA Travel, which specialize in youth travel, or CWT, which caters to corporate travel. Many use telecommuting to reduce overhead, and/or provide concierge services. Agents can act as "travel consultants" with flawless knowledge of destination regions and specialize in topics like nautical tourism or cultural tourism. Many traditional agents prefer the term "travel advisor" as opposed to "travel agent" to emphasize their advice, expertise, and connections that are of great value. Outbound travel agencies offer multi-destinations; inbound travel agencies are based in the destination and deliver an expertise on that location.

Input: Consider Input: Passage: Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.
