[Q]: 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:  Where did Johann Sebastian Bach play  Erschallet, ihr Lieder, erklinget, ihr Saiten! in 1723?

[Q]: Given the following context:  Both men were suffering, but Mertz in particular started to feel ill. He complained of stomach pains, and this began to slow them down. Pavlova was killed, leaving only one remaining dog. Mawson decided to lighten their sledge, and much of the equipment—including the camera, photographic films, and all of the scientific equipment save the theodolite—was abandoned. On 29 December, the day they cleared the Ninnis Glacier, the last dog was killed. Mawson recorded: "Had a great breakfast off Ginger's skull—thyroids and brain". Two days later Mawson recorded that Mertz was "off colour"; Mertz wrote that he was "really tired [and] shall write no more".They made 5 miles (8.0 km) on 31 December, no progress for the following two days, and 5 miles more on 3 January. "[The] cold wind frost-bit Mertz's fingers" recorded Mawson, "and he is generally in a very bad condition. Skin coming off legs, etc—so had to camp though going was good." Not until 6 January did they make any more progress; they went 2 miles (3.2 km) before Mertz collapsed. The following day Mawson placed Mertz onto the sledge in his sleeping bag and continued, but was forced to stop and camp when Mertz's condition again deteriorated. Mawson recorded: He is very weak, becomes more and more delirious, rarely being able to speak coherently. He will eat or drink nothing. At 8 pm he raves & breaks a tent pole. Continues to rave & call 'Oh Veh, Oh Veh' [O weh!, 'Oh dear!'] for hours. I hold him down, then he becomes more peaceful & I put him quietly in the bag. He dies peacefully at about 2 am on morning of 8th. Strong winds prevented Mawson from continuing for two days. Instead, he prepared for travelling alone, removing the rearmost half from the sledge, and rearranging its cargo. To save having to carry excess kerosene for the stove, he boiled the remainder of the dog meat. Dragging Mertz's body in the sleeping bag from the tent, Mawson constructed a rough cairn from snow blocks to cover it, and used two spare beams from the sledge to form a cross, which he...  answer the following question:  What did Mawson construct a rough cairn from snow blocks to cover?

[Q]: Given the following context:  While driving his Dual-Ghia from Las Vegas to Los Angeles, lecherous, heavy-drinking pop singer Dino is forced to detour through Climax, Nevada. There he meets the amateur songwriting team of Barney Millsap, a gas station attendant, and piano teacher Orville J. Spooner, a man easily given to jealousy. Hoping to interest Dino in their songs, Barney disables the "Italian" sports car and tells Dino he will need to remain in town until new parts arrive from Milan. (Dual-Ghia was actually an American marque, mating a Dodge frame, drivetrain, and engine with Italian coachwork.) Orville invites Dino to stay with him and wife Zelda, but becomes concerned when he learns the singer needs to have sex every night to avoid awakening with a headache. Anxious to accommodate Dino but safeguard his marriage, Orville provokes an argument with his wife that leads to Zelda fleeing in tears. He and Barney then arrange for Polly the Pistol, a waitress and prostitute at a saloon on the edge of town called the Belly Button, to pose as Orville's wife and satisfy Dino. That evening after the three have dinner, Orville plays his tunes for Dino on the piano and Polly requests a particular song. It is one she knows he wrote for his wife when trying to persuade her to marry him. Doing so, Orville gets lost in emotion, as does Polly, who has fallen a little for the dream of a domestic life that she doesn't have. Under the influence of wine and song, Orville starts thinking of Polly as his wife and tosses Dino out. He then spends the night with Polly.  answer the following question:  What is the last name of the person who disables the sports car?
