The questions are based on English literary interpretation where 'gigantic bats of delirium and night fever' refer to 'crazed thoughts', 'not very rigid or hierarchical' suggest a system not 'arranged by rank' and 'in the mayhem of other boys’ arms and legs' signifies 'confusion'.
The subject of these questions is English, specifically focused on understanding the usage of specific phrases or words within different contexts of literature. For the first question, "gigantic bats of delirium and night fever" could be interpreted as a metaphor suggesting crazed thoughts as delirium often refers to a mental state marked by confusion and hallucinations. In the second question, "not very rigid or hierarchical" indicates that the management was not arranged by a rank system. In the final question, "in the mayhem of other boys’ arms and legs" indicates a scene of confusion where the ball got lost amidst the chaos.

The bag is more concentrated in starch than the beaker. This is because the bag contains a solution of starch and water, while the beaker contains only water.
The starch molecules are unable to pass through the plastic bag, so they remain concentrated in the bag. The water molecules, however, are able to pass through the bag, so they diffuse into the beaker, making the solution in the beaker less concentrated in starch.
If you were to leave the bag and beaker for a long enough period of time, all of the starch molecules would eventually diffuse into the beaker, and the concentration of starch in both the bag and beaker would be the same. However, in practice, this would take a very long time, as the rate of diffusion is relatively slow.
