數學 standard deviation在英文題目的翻譯

During an experiment, some water was removed from each of 6 water tanks. If the standard deviation of the volumes of water in the tanks at the beginning of the experiment was 10 gallons, what was the standard deviation of the volumes of water in the tanks at the end of the experiment?

(1) For each tank, 30 percent of the volume of water that was in the tank at the beginning of the experiment was removed during the experiment.

(2) The average (arithmetic mean) volume of water in the tanks at the end of the experiment was 63 gallons.

我不太懂此句:what was the standard deviation of the volumes of water in the tanks at the end of the experiment?

答案是(1),可是題目問:the end of the experiment? 而(1)是 at the beginning of the experiment

真的不能理解耶

請英文高手幫忙謝謝~~
