Question: Assume both beakers were initially filled with pure water at 20 °C, and the two white powders added have exactly the same mass. Now, if a laser beam is sent horizontally through the clear upper layer of liquid in each beaker, in which beaker will the light path be more clearly visible?
A. The left beaker
B. The right beaker
C. Both are clearly visible
D. Neither is visible
Clues:
1. The image shows two beakers being compared before and after a period of time.
2. The Chinese text "一段时间后" indicates the right side of the image shows the beakers "after a period of time".
3. In the beaker on the left (after time has passed), a large amount of white solid has settled at the bottom.
4. In the beaker on the right (after time has passed), there is no significant amount of settled solid at the bottom.
5. The liquid in both beakers is a translucent yellow color.
6. In the initial state, a person is stirring the contents of both beakers with glass rods.
