QUES: The distances passengers need to move within a large airport can be substantial. It is common for airports to provide moving walkways and buses. The Hartsfield–Jackson Atlanta International Airport has a tram that takes people through the concourses and baggage claim. Major airports with more than one terminal offer inter-terminal transportation, such as Mexico City International Airport, where the domestic building of Terminal 1 is connected by Aerotrén to Terminal 2, on the other side of the airport.
What airport offers a moving walkway to baggage claim?

QUES: As the Kulluk oil rig was being towed to the American state of Washington to be serviced in preparation for the 2013 drilling season, a winter storm on 27 December 2012 caused the towing crews, as well as the rescue service, to lose control of the situation. As of 1 January 2013, the Kulluk was grounded off the coast Sitkalidak Island, near the eastern end of Kodiak Island. Following the accident, a Fortune magazine contacted Larry McKinney, the executive director at the Harte Research Institute for Gulf of Mexico Studies at Texas A&M, and he explained that "A two-month delay in the Arctic is not a two-month delay ... A two-month delay could wipe out the entire drilling season."
How long did it take to tow the Kulluk to Washington state?

QUES: Network effects are a large factor with electrification. When converting lines to electric, the connections with other lines must be considered. Some electrifications have subsequently been removed because of the through traffic to non-electrified lines. If through traffic is to have any benefit, time consuming engine switches must occur to make such connections or expensive dual mode engines must be used. This is mostly an issue for long distance trips, but many lines come to be dominated by through traffic from long-haul freight trains (usually running coal, ore, or containers to or from ports). In theory, these trains could enjoy dramatic savings through electrification, but it can be too costly to extend electrification to isolated areas, and unless an entire network is electrified, companies often find that they need to continue use of diesel trains even if sections are electrified. The increasing demand for container traffic which is more efficient when utilizing the double-stack car also has network effect issues with existing electrifications due to insufficient clearance of overhead electrical lines for these trains, but electrification can be built or modified to have sufficient clearance, at additional cost.
Where can the issue of through traffic benefits occur?

ANS: long distance trips

QUES: A red dye called Kermes was made beginning in the Neolithic Period by drying and then crushing the bodies of the females of a tiny scale insect in the genus Kermes, primarily Kermes vermilio. The insects live on the sap of certain trees, especially Kermes oak trees near the Mediterranean region. Jars of kermes have been found in a Neolithic cave-burial at Adaoutse, Bouches-du-Rhône. Kermes from oak trees was later used by Romans, who imported it from Spain. A different variety of dye was made from Porphyrophora hamelii (Armenian cochineal) scale insects that lived on the roots and stems of certain herbs. It was mentioned in texts as early as the 8th century BC, and it was used by the ancient Assyrians and Persians.
