This question is incomplete. The rest of the question is listed below:

To measure the volume of the starch-water mixture in the dialysis bag, the students should have used a (1) meterstick (3) graduated cylinder (2) triple-beam balance (4) test tube

The answer is 3) graduated cylinder. A measuring stick to measure depth would not have worked as the overall volume of the beaker containing the dialysis bag would not have changed. A test tube would generally have insufficient volume to measure the volume of the dialysis bag and a test tube is generally not graduated. A triple beam balance is generally used to weigh mass and not volume.
