[A]: 38


[Q]: Passage: Before Rollo's arrival, its populations did not differ from Picardy or the Île-de-France, which were considered 'Frankish'. Earlier Viking settlers had begun arriving in the 880s, but were divided between colonies in the east (Roumois and Pays de Caux) around the low Seine valley and in the west in the Cotentin Peninsula, and were separated by traditional pagii, where the population remained about the same with almost no foreign settlers. Rollo's contingents who raided and ultimately settled Normandy and parts of the Atlantic coast included Danes, Norwegians, Norse–Gaels, Orkney Vikings, possibly Swedes, and Anglo-Danes from the English Danelaw under Norse control. Question: Who upon arriving gave the original viking settlers a common identity?
[A]: Rollo


[Q]: Passage: Despite their soft, gelatinous bodies, fossils thought to represent ctenophores, apparently with no tentacles but many more comb-rows than modern forms, have been found in lagerstätten as far back as the early Cambrian, about 515 million years ago. The position of the ctenophores in the evolutionary family tree of animals has long been debated, and the majority view at present, based on molecular phylogenetics, is that cnidarians and bilaterians are more closely related to each other than either is to ctenophores. A recent molecular phylogenetics analysis concluded that the common ancestor of all modern ctenophores was cydippid-like, and that all the modern groups appeared relatively recently, probably after the Cretaceous–Paleogene extinction event 66 million years ago. Evidence accumulating since the 1980s indicates that the 'cydippids' are not monophyletic, in other words do not include all and only the descendants of a single common ancestor, because all the other traditional ctenophore groups are descendants of various cydippids. Question: Evidence indicates that Cydippids are not what?
[A]:
monophyletic
