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.

Question: 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.


Answer: These neurons have high activation during wakefulness and during REM sleep and a low activation during NREM sleep


Question: Question: How many Nobel Prizes in Physics were awarded before it was given to Leo Esaki? Passage:A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tunnel diodes were first manufactured by Sony in 1957, followed by General Electric and other companies from about 1960, and are still made in low volume today.


Answer: In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes


Question: Question: Comparing the places Naipaul visited while writing his book, what is the difference in population between the two? Passage:Black & White is a non-fiction book written by Shiva Naipaul and published by Hamish Hamilton in the U.K. in 1980. It was published with the title Journey to Nowhere: A New World Tragedy in the U.S. The book is based on Naipaul's trip to Guyana in the aftermath of the Jonestown Massacre, and his subsequent trip to the United States, in which he explored links between the People's Temple and other groups and individuals. Naipaul attempted to connect Rev. Jim Jones, founder of the People's Temple, with disparate parts of California's counterculture, and Guyanese and other Third World governments and the revolutionary ideologies which supported them. Naipaul was highly critical of these and other movements, including black theology, the nascent New Age movement and EST, in as much as they helped, in his analysis, to create fertile ground for the People's Temple to flourish on the two continents. The book's US paperback cover tagline reads "How American ideas and ideologies led to the mass suicide of 900 people in Jonestown, Guyana."


Answer:
The book is based on Naipaul's trip to Guyana in the aftermath of the Jonestown Massacre, and his subsequent trip to the United States, in which he explored links between the People's Temple and other groups and individuals
