Good A &gt; B &gt; C When the third absorption rate exceeded 〇〇/〇, it was regarded as absorption. Excellent sex, evaluation 21 20125008α is 'Α,. The second absorption rate When the absorption rate was 0% and the third absorption rate was 0%, the evaluation was 'B'. When the second absorption rate was 0%, the absorption was considered to be poor, and it was evaluated as 'C'. The artificial urine is prepared using the following composition ratio. Urea.........
