问题 有A、B、C、D外表一样、重量不同的四个小球。已知:A+B=C+D;A+D>B+C;A+CA. D>B>A>C B. B>C>D>A C. D>B>C>
选项 A. B> C> D>
答案 A
解析 设A+B=C+D为①式,A+D>B+C为②式,A+CB-D,故D>B,排除选项B、D。对比A、C项,只比较A和C的大小即可。由①可知,A-C = D-B>0。故A>C。本题选A。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
