选项

答案 C

解析一般情况下，当书包受到的重力固定时，对肩膀的压力也是固定的，书包背带做得宽是为了增大受力面积从而减小压强，使背包者的肩部舒服些。故C项的说法错误，本题正确答案选C。

错误信息

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. 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). Please check the Redis logs for details about the RDB error.
