Ex Input:
passage: The hippocampus (named after its resemblance to the seahorse, from the Greek ἱππόκαμπος, ``seahorse'' from ἵππος hippos, ``horse'' and κάμπος kampos, ``sea monster'') is a major component of the brains of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located under the cerebral cortex (allocortical) and in primates in the medial temporal lobe. It contains two main interlocking parts: the hippocampus proper (also called Ammon's horn) and the dentate gyrus.
 question: is the hippocampus part of the brain stem?

Ex Output:
No


Ex Input:
passage: The alcohol laws of the United States regarding minimum age for purchase have changed over time. The history is given in the table below. Unless otherwise noted, if different alcohol categories have different minimum purchase ages, the age listed below is set at the lowest age given (e.g. if the purchase age is 18 for beer and 21 for wine or spirits, as was the case in several states, the age in the table will read as ``18'', not ``21''). In addition, the purchase age is not necessarily the same as the minimum age for consumption of alcoholic beverages, although they have often been the same.
 question: is the drinking age 21 in all us states?

Ex Output:
No
