Given the following context:  The film adopts a linear plot. Ice Quake is an action film about the Alaskan landscape, where there is a great threat that is going to affect the beautiful and gentle scenery. Under the permafrost, organic materials have been rotting for thousands of years and the compound is very deadly to the planet. As the permafrost thaws, underground volatile liquid methane and gases are created which causes a succession of violent and very destructive earthquakes. A family ends up going to this Alaskan landscape on the hunt for a Christmas tree, hoping to have fun, and unfortunately finds out firsthand how deadly this can be. As they are exploring these mountains,  their dog runs away for an unknown reason and soon after there is an explosion of gas from underneath the ice that ends up causing an avalanche. The family has to run for their lives. The father takes charge and tries to lead them to safety when suddenly another tremor occurs. This time, it causes the ground to split open, creating a deep ravine dividing the family apart - the parents on one side and two children on the other. They cannot group back together as there is dangerous gas flowing out the ravine so the father tell them to go to the summit and wait for rescue. The children head up to top to then find out there is a storm on their way causing more concern. The younger brother suggests they keep moving until they can stop at a safe place As this chaos is going on, the military based around the mountain are investigating the tremors. At first believed the tremors were being caused by earthquakes but then discover that there have been no tectonic movements and nothing has showed on the Richter scale. They then thought it could have been a volcano eruption causing this but also ends up to be false. It is a race against time to stop these harmful liquids and gases before it leads to a catastrophic explosion that threatens the planet.  answer the following question:  What are the people whose dog runs away looking for?
Ans: a Christmas tree

Given the following context:  L'Orfeo (SV 318) (Italian pronunciation: [lorˈfɛːo]), sometimes called La favola d'Orfeo [la ˈfaːvola dorˈfɛːo], is a late Renaissance/early Baroque favola in musica, or opera, by Claudio Monteverdi, with a libretto by Alessandro Striggio. It is based on the Greek legend of Orpheus, and tells the story of his descent to Hades and his fruitless attempt to bring his dead bride Eurydice back to the living world. It was written in 1607 for a court performance during the annual Carnival at Mantua. While Jacopo Peri's Dafne is generally recognised as the first work in the opera genre, and the earliest surviving opera is Peri's Euridice, L'Orfeo is the earliest that is still regularly performed. By the early 17th century the traditional intermedio—a musical sequence between the acts of a straight play—was evolving into the form of a complete musical drama or "opera". Monteverdi's L'Orfeo moved this process out of its experimental era and provided the first fully developed example of the new genre. After its initial performance the work was staged again in Mantua, and possibly in other Italian centres in the next few years. Its score was published by Monteverdi in 1609 and again in 1615. After the composer's death in 1643 the opera went unperformed for many years, and was largely forgotten until a revival of interest in the late 19th century led to a spate of modern editions and performances. At first these performances tended to be concert (unstaged) versions within institutes and music societies, but following the first modern dramatised performance in Paris, in 1911, the work began to be seen in theatres. After the Second World War many recordings were issued, and the opera was increasingly staged in opera houses, although some leading venues resisted it. In 2007, the quatercentenary of the premiere was celebrated by performances throughout the world. In his published score Monteverdi lists around 41 instruments to be deployed, with distinct groups of instruments used to depict particular scenes and characters....  answer the following question:  In what year did L'Orfeo celebrate its quatercentenary?
Ans: 2007

Given the following context:  Johann Sebastian Bach composed the church cantata Erschallet, ihr Lieder, erklinget, ihr Saiten! (Ring out, you songs; sound, you strings!), BWV 172, in Weimar for Pentecost Sunday in 1714. Bach led the first performance on 20 May 1714 in the Schlosskirche, the court chapel in the ducal Schloss. Erschallet, ihr Lieder is an early work in a genre to which he later contributed complete cantata cycles for all occasions of the liturgical year. Bach was appointed Konzertmeister in Weimar in the spring of 1714, a position that called for the performance of a church cantata each month. He composed Erschallet, ihr Lieder as the third cantata in the series, to a text probably written by court poet Salomon Franck. The text reflects different aspects of the Holy Spirit. The librettist included a quotation from the day's prescribed Gospel reading in the only recitative, and for the closing chorale he used a stanza from Philipp Nicolai's hymn "Wie schön leuchtet der Morgenstern" (1599). The work is in six movements, and scored for four vocal soloists, four-part choir, three trumpets, timpani, oboe, bassoon and a string orchestra of two violins, two violas, and basso continuo. The orchestra for the holiday occasion is festive compared to the two works previously composed in Weimar. The cantata opens with a chorus, followed by the recitative, in which words spoken by Jesus are sung by the bass as the vox Christi (voice of Christ). A bass aria with trumpets addresses the Trinity, and a tenor aria then describes the Spirit that was present at the Creation. This is followed by an intimate duet of the Soul (soprano) and the Spirit (alto), to which an oboe plays the ornamented melody of Martin Luther's hymn "Komm, Heiliger Geist, Herre Gott" and a solo cello provides the bass line. The theme of intimacy between God and Man is developed further in the following chorale, after which Bach specified an unusual repeat of the opening chorus. While Bach served as Thomaskantor – director of church music – in Leipzig from 1723, he...  answer the following question:  What is the last name of the person who served as Thomaskantor?
Ans: Bach
