问题
People in a large area may possess the same DNA thread because ______ . [br] The Molecular Genealogy Research Group is building a database for the purpose of ______ .
选项
A、offering assistance in working out genealogy-related problems
B、solving many issues without relying on traditional written records
C、providing a pedigree chart of at least four generations in the world
D、confirming the assumption that all individuals are of the same origin
答案
A
解析
细节题。 题干问的是建数据库的目的,解题关键在第二段中:“help in solving many issues regarding genealogies that could not be done by relying only (仅靠…不能解决与宗谱相关的诸多问题)”。A意为“解决宗谱有关的问题时提供帮助”,是正确答案。其余选项均不正确。B意为“无须依赖传统文字资料解决许多问题”;C意为“提供世界至少四代人的家谱”;D意为“核实所有个体都有同样祖先的假设”。
