Answer: B. Water molecules slow down until they begin to bond together.
Explanation: When water is cooled, energy is removed from the system, and the molecules begin to slow down. When the molecules have slowed suciently, their collisions are no longer energetic enough to overcome their electrostatic attraction, and they begin to bond together. The other answer choices are inaccurate. Since ice is less dense than water, high pressure compresses the ice and actually causes it to melt. (Compression has no effect on water volume.) Cooling has no effect on the shape of individual water molecules.
I would say (A) because it allows the bacteria (bacteria X) to be exposed to the control condition and the experimental condition so that a cause-effect relationship can be established. Here, the control condition would be the darkened area and the experimental condition would be the lightened area.

To be accepted, a scientific argument must first proved it's solidity and validity and critiques from other expert is usually the best way to explain both the solidity and the validity of a scientific argument
