In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

[Q]: Question: which phase of sleep is the longest? Passage:Von Economo, in his studies, noticed that lesions in the connection between the midbrain and the diencephalon caused prolonged sleepiness and therefore proposed the idea of an ascending arousal system. During the past few decades major ascending pathways have been discovered with located neurons and respective neurotransmitters. This pathway divides into two branches: one that ascends to the thalamus and activates the thalamus relay neurons, and another one that activates neurons in the lateral part of the hypothalamus and the basal forebrain, and throughout the cerebral cortex. The cell group involved in the first pathway is an acetylcholine-producing cell group called pedunculopontine and laterodorsal tegmental nucleus(PPT/LDT). These neurons play a crucial role in bridging information in between the thalamus and the cerebral cortex. These neurons have high activation during wakefulness and during REM sleep and a low activation during NREM sleep. The second branch originates from monoaminorgenic neurons. These neurons are located in the locus coeruleus, dorsal and median raphe nuclei, ventral periaqueductal grey matter, and tuberomammillary nucleus. Each group produces a different neurotransmitter. The neurons in the locus coeruleus produce noradrenaline, as fore the neurons in the dorsal and median raphe nuclei, ventral periaqueductal grey matter, and tuberomammillary nucleus produce serotonin, dopamine and histamine respectively. They then project onto the hypothalamic peptidergic neurons, which contain melanin-concentrated hormones or orexin, and basal forebrain neurons which contain GABA and acetylcholine. These neurons then project onto the cerebral cortex. It has also been discovered that lesions to this part of the brain cause prolonged sleep or may produce coma.

[A]: These neurons have high activation during wakefulness and during REM sleep and a low activation during NREM sleep


[Q]: Question: Where was the person who was hired to replace Vai born? Passage:Roth hired 19-year-old guitar virtuoso Jason Becker to replace Vai prior to recording his third solo LP, A Little Ain't Enough. A straight-ahead hard rock album produced by Bob Rock (who had just produced Metallica's self-titled album), A Little Ain't Enough achieved RIAA gold status shortly after its January 1991 release. Before starting a support tour for A Little Ain't Enough, Becker was diagnosed with Lou Gehrig's disease, rendering him unable to perform onstage. Guitarist Joe Holmes stood in for Becker during the tour. Later in 1991, Nirvana and grunge rock emerged, altering musical tastes and suddenly making Roth's brand of hard rock seem unfashionable. Roth's band fractured shortly following the tour's completion. With one exception – 1997's well-received DLR Band album, featuring guitarist John 5 and drummer Ray Luzier – until his reconciliation with Van Halen in 2006, Roth would utilize hired-hands and studio musicians on his club and amphitheater solo tours.

[A]: Roth hired 19-year-old guitar virtuoso Jason Becker to replace Vai prior to recording his third solo LP, A Little Ain't Enough


[Q]: Question: Where was the person whose guard Yermolov served in 1807 born? Passage:His own military genius blossomed during the Napoleonic Wars. During the 1805 Campaign, Yermolov served in the rear and advance guards and distinguished himself at Amstetten and Austerlitz. For his actions, he was promoted to colonel on 16 July 1806. The following year, he participated in the campaign in Poland, serving in Prince Bagration's advance guard. He distinguished himself commanding an artillery company in numerous rearguard actions during the retreat to Landsberg as well as in the Battle of Eylau. In June 1807, Yermolov commanded horse artillery company in the actions at Guttstadt, Deppen, Heilsberg and Friedland, being awarded the Order of St. George (3rd class, 7 September 1807). He was promoted to major general on 28 March 1808 and was appointed inspector of horse artillery companies. In early 1809, he inspected artillery companies of the Army of the Danube. Although his division took part in the 1809 campaign against Austria, Yermolov commanded the reserves in Volhynia and Podolsk gubernias, where he remained for the next two years. In 1811, he took command of the guard artillery company and in 1812, became the Chief of Staff of the 1st Western Army.

[A]:
