Input: Read this: Ectosymbiosis, also referred to as exosymbiosis, is any symbiotic relationship in which the symbiont lives on the body surface of the host, including the inner surface of the digestive tract or the ducts of exocrine glands. Examples of this include ectoparasites such as lice, commensal ectosymbionts such as the barnacles that attach themselves to the jaw of baleen whales, and mutualist ectosymbionts such as cleaner fish.
Question: What ectoparasites are also considered commensal ectosymbionts and mutualist ectosymbionts?

QUES: The organ was built by Harrison & Harrison in 1937, then with four manuals and 84 speaking stops, and was used for the first time at the coronation of King George VI. Some pipework from the previous Hill organ of 1848 was revoiced and incorporated in the new scheme. The two organ cases, designed in the late 19th century by John Loughborough Pearson, were re-instated and coloured in 1959.

When was the organ destroyed?

QUES: A typical pommel horse exercise involves both single leg and double leg work. Single leg skills are generally found in the form of scissors, an element often done on the pommels. Double leg work however, is the main staple of this event. The gymnast swings both legs in a circular motion (clockwise or counterclockwise depending on preference) and performs such skills on all parts of the apparatus. To make the exercise more challenging, gymnasts will often include variations on a typical circling skill by turning (moores and spindles) or by straddling their legs (Flares). Routines end when the gymnast performs a dismount, either by swinging his body over the horse, or landing after a handstand. This requires back muscles to do any sort of skill. From handstands being easy to back or front flips being a little difficult.
What is the main staple of this event?

ANS: Double leg work

The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. Glaciers can be found in all latitudes except from 20 to 27 north and south of the equator where the presence of the descending limb of the Hadley circulation lowers precipitation so much that with high insolation snow lines reach above 6,500 m (21,330 ft). Between 19N and 19S, however, precipitation is higher and the mountains above 5,000 m (16,400 ft) usually have permanent snow.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can be found in every country from 20 degrees to 27 degess north and south of the equator?
Ah, so.. unanswerable

Question: St. John's is the eastern terminus of the Trans-Canada Highway, one of the longest national highways in the world. The divided highway, also known as "Outer Ring Road" in the city, runs just outside the main part of the city, with exits to Pitts Memorial Drive, Topsail Road, Team Gushue Highway, Thorburn Road, Allandale Road, Portugal Cove Road and Torbay Road, providing relatively easy access to neighbourhoods served by those streets. Pitts Memorial Drive runs from Conception Bay South, through the city of Mount Pearl and into downtown St. John's, with interchanges for Goulds, Water Street and Hamilton Avenue-New Gower Street.
Try to answer this question if possible: Where is the eastern terminus of the Trans-Canada Highway?

QUES: Hard rock is a form of loud, aggressive rock music. The electric guitar is often emphasised, used with distortion and other effects, both as a rhythm instrument using repetitive riffs with a varying degree of complexity, and as a solo lead instrument. Drumming characteristically focuses on driving rhythms, strong bass drum and a backbeat on snare, sometimes using cymbals for emphasis. The bass guitar works in conjunction with the drums, occasionally playing riffs, but usually providing a backing for the rhythm and lead guitars. Vocals are often growling, raspy, or involve screaming or wailing, sometimes in a high range, or even falsetto voice.
