Q: 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.

Q: Passage: The first archaeological investigation of the site was carried out in 1964. In that year, the site was noted during an archaeological survey of the region directed by Maurits N. van Loon of the Oriental Institute of the University of Chicago, and a small sounding was made. In 1965, a more extensive excavation was carried out, again under the direction of Van Loon. Between 1971 and 1974, work on the site was resumed by a team of the French Centre national de la recherche scientifique (CNRS) directed by Jacques Cauvin. All excavations were part of the larger international and eventually UNESCO-coordinated effort to investigate as many archaeological sites as possible in the area that would be flooded by Lake Assad, the reservoir of the Tabqa Dam, which was being built at that time. The filling of Lake Assad eventually led to the flooding of Mureybet in 1976. Although the site is now submerged and no longer accessible, the material that has been retrieved during the excavations continues to generate new research. This material is currently stored at the National Museum of Aleppo and the Institute de Prehistoire Orientale in Jales-Berrias in France.

Q: Passage: The Eagles competed in three tournaments during the 201617 season, the first of which took place during the traditional opening of the college hockey season at the 20th annual Ice Breaker Classic. Played on October 7 and 8 at Magness Arena in Denver, Colorado, the tournament showcased the Eagles playing Air Force in the first round, where they would lose a tight 2-1 match. Boston College faced host Denver in the consolation round, picking up a 3-1 victory for their first win of the season. Air Force would defeat Ohio State in the championship. The Eagles had previously won the ice breaker tournament three times; making their fifth appearance this season. The second tournament of the season took place during the holiday break, where the Eagles made the trip to the PPG Paints Arena in Pittsburgh, Pennsylvania for their second appearance in the Three Rivers Classic in its fifth annual year. The Eagles fell 31 to the Quinnipiac Bobcats in the opening round, but picked up the 3rd-place result against Ferris State in the consolation round, winning the (unofficial) shootout of the (official) 11 tie. Boston College previously won the title in their first appearance at the tournament in 2012. For their final tournament of the season, the Eagles played in the 65th Annual Beanpot Tournament at the TD Garden in Boston, Massachusetts on February 6 and 13. Boston College lost to rival Boston University 31 in the opening round (suffering their first season sweep against the Terriers since 199495), and were defeated by Northeastern 24 in the consolation game, marking the first 4th place finish for the Eagles since 1993 and the first of Jerry York's tenure.
