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: Who was Roland I's mother? Passage:Roland I was born around 1215 into the gens Rátót as the son of Dominic I, who served as Master of the treasury from 1238 to 1240. He was killed in the Battle of Mohi in 1241. The ancestors of the kindred were two Norman knights (Oliver and Rathold) from Caserta, Naples, who settled down in Hungary around 1097 during the reign of Coloman, King of Hungary. Roland's earliest known ancestor was his great-grandfather Leustach I Rátót, Voivode of Transylvania in the second half of the 12th century. Roland had three brothers, Stephen, the forefather of the Pásztói, Tari and Kakas de Kaza noble families. The Putnoki family came from Oliver I. Leustach II was the father of Palatine Roland II Rátót and also the ancestor of the Jolsvai, Serkei and Feledi branches. Their only unidentified sister married Maurice II Pok whom the influential baron Nicholas Pok originated.

[A]: Roland I was born around 1215 into the gens Rátót as the son of Dominic I, who served as Master of the treasury from 1238 to 1240


[Q]: Question: Did William IV's younger daughter have more than 3 children? Passage:In 1905, Grand Duke Adolphe's younger half-brother, Prince Nikolaus Wilhelm of Nassau, died, having left a son Georg Nikolaus, Count von Merenberg who was, however, the product of a morganatic marriage, and therefore not legally a member of the House of Nassau. In 1907, Adolphe's only son, William IV, Grand Duke of Luxembourg, obtained passage of a law confirming the right of his eldest daughter, Marie-Adélaïde, to succeed to the throne in virtue of the absence of any remaining dynastic males of the House of Nassau, as originally stipulated in the Nassau Family Pact. She became the grand duchy's first reigning female monarch upon her father's death in 1912, and upon her own abdication in 1919, was succeeded by her younger sister Charlotte, who married Felix of Bourbon-Parma, a prince of the former Duchy of Parma. Charlotte's descendants have since reigned as the continued dynasty of Nassau, and also constitute a cadet branch of the House of Bourbon-Parma.
