Q: Information: - Not to be confused with Wharton 's duct ( submandibular duct ) Warthin 's tumor or Warthin tumour , also known as papillary cystadenoma lymphomatosum , monomorphic adenoma or adenolymphoma , is a benign cystic tumor of the salivary glands containing abundant lymphocytes and germinal centers ( lymph node - like stroma ) . It is named for pathologist Aldred Scott Warthin , who described two cases in 1929 . - Cystadenoma (or "cystoma") is a type of cystic adenoma. - An adenoma (from Greek , "adeno-", "gland" + -, "-oma", "tumor") (plural adenomas or adenomata ) is a benign tumor of epithelial tissue with glandular origin, glandular characteristics, or both. Adenomas can grow from many glandular organs, including the adrenal glands, pituitary gland, thyroid, prostate, and others. Some adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure (as can happen in familial polyposis coli). Although adenomas are benign, over time they may transform to become malignant, at which point they are called adenocarcinomas. Most adenomas do not transform. But even while benign, they have the potential to cause serious health complications by compressing other structures (mass effect) and by producing large amounts of hormones in an unregulated, non-feedback-dependent manner (causing paraneoplastic syndromes). Some adenomas are too small to be seen macroscopically but can still cause clinical symptoms. After reading the paragraphs above, choose the best answer for the entity that related to 'warthin's tumor' with the relationship of 'instance of'. Choices: - benign tumor - gland - health - mass - structure - tissue
A: benign tumor

Q: Information: - Neritoidea is a taxonomic superfamily of mostly sea snails, nerites and their allies, marine gastropod mollusks in the clade Cycloneritimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). - The Gastropoda or gastropods, more commonly known as snails and slugs, are a large taxonomic class within the phylum Mollusca. The class Gastropoda includes snails and slugs of all kinds and all sizes from microscopic to large. There are many thousands of species of sea snails and sea slugs, as well as freshwater snails, freshwater limpets, land snails and land slugs. - Neritoida was a taxonomic order of sea snails , freshwater snails and land snails , gastropod molluscs . This order was placed within the superorder Neritopsina within the order Orthogastropoda . Now see Neritoidea . - Orthogastropoda was a major taxonomic grouping of snails and slugs, an extremely large subclass within the huge class Gastropoda according to the older taxonomy of the Gastropoda (Ponder & Lindberg, 1997). - Cycloneritimorpha (nerites and false-limpets) is a clade of land snails, freshwater snails, and sea snails. These are gastropod molluscs within the larger clade Neritimorpha. 14 of the families in the clade are extant, and eight of the families are extinct. - Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs. However, the common name "snail" is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as "snails". After reading the paragraphs above, choose the best answer for the entity that related to 'neritoida' with the relationship of 'parent taxon'. Choices: - animal - cycloneritimorpha - gastropoda - neritimorpha - neritoidea - orthogastropoda
A: neritimorpha
