How many questions have been solved up till now?
A twenty-two-year-old student here may have solved one of the great enigmas of mathematics. Elin Oxenhielm of Stockholm University’s solution of part of Hilbert’s sixteenth problem will be published next week.In 1900, German mathematician David Hilbert presented a set of 23 unsolved problems to a congress in Paris. Three remain unsolved today: numbers six, eight, and sixteen. The sixteenth problem calls for the creation of a topology of real algebraic curves and surfaces. The solution for the second part of the problem is being published in the journal, Nonlinear Analysis.
选项
A、16.
B、8.
C、6.
D、20.
答案
D
解析
数字计算题。在短短的新闻中涉及到了多个数字,但是没有哪个数字是可以直接用来回答问题的。问题问的是有多少问题已经得到了解决,这点在新闻中并没有直接说明。但根据“……提出一系列共23个悬而未决的数学难题。到今天仍有3个问题是未解之谜。”这句话,我们很快可以计算出正确答案是20,所以在此应该选择D项。
