In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: What needs consistency?, Context: The simplest valve gears give events of fixed length during the engine cycle and often make the engine rotate in only one direction. Most however have a reversing mechanism which additionally can provide means for saving steam as speed and momentum are gained by gradually "shortening the cutoff" or rather, shortening the admission event; this in turn proportionately lengthens the expansion period. However, as one and the same valve usually controls both steam flows, a short cutoff at admission adversely affects the exhaust and compression periods which should ideally always be kept fairly constant; if the exhaust event is too brief, the totality of the exhaust steam cannot evacuate the cylinder, choking it and giving excessive compression ("kick back").[citation needed]
[A]: exhaust and compression periods


[Q]: Who was responsible for Universal before Junior?, Context: "Junior" Laemmle persuaded his father to bring Universal up to date. He bought and built theaters, converted the studio to sound production, and made several forays into high-quality production. His early efforts included the critically mauled part-talkie version of Edna Ferber's novel Show Boat (1929), the lavish musical Broadway (1929) which included Technicolor sequences; and the first all-color musical feature (for Universal), King of Jazz (1930). The more serious All Quiet on the Western Front (1930), won its year's Best Picture Oscar.
[A]: his father


[Q]: What is a noble death?, Context: According to the Secret History, Temüjin again offered his friendship to Jamukha, asking him to return to his side. Temüjin had killed the men who betrayed Jamukha, stating that he did not want disloyal men in his army. Jamukha refused the offer of friendship and reunion, saying that there can only be one sun in the sky, and he asked for a noble death. The custom is to die without spilling blood, which is granted by breaking the back. Jamukha requested this form of death, despite the fact that in the past Jamukha had been known to have boiled his opponents' generals alive.
