Question ID:PT35 S1 Q11 Passage:Linguist:  Some people have understood certain studies as showing that bilingual children have a reduced "conceptual map" because bilingualism overstresses the child's linguistic capacities. Vocabulary tests taken by bilingual children appear to show that these children tend to have a smaller vocabulary than do most children of the same age group. But these studies are deeply flawed, since the tests were given in only one language. Dual-language tests revealed that the children often expressed a given concept with a word from only one of their two languages. Stem:The linguist's argument proceeds by Correct Answer Choice:EChoice A:offering evidence for the advantages of bilingualism over monolingualism Choice B:pointing out an inconsistency in the view that bilingualism overstresses a child's linguistic capabilities Choice C:offering evidence that undermines the use of any vocabulary test to provide information about a child's conceptual map Choice D:providing a different explanation for the apparent advantages of bilingualism from the explanation suggested by the results of certain studies Choice E:pointing out a methodological error in the technique used to obtain the purported evidence of a problem with bilingualism
