The correct answer is C. Here's why:
Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory.
Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods.
Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.
Answer:
This is the last law of thermodynamics that we know of so far. The zeroth law of thermodynamics states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other.

Answer:
C. The village probably cannot afford a desalination plant.
Explanation:
Desalination may be defined as treating water to make it consumable for human use and drinking purposes.
A desalinated plant separates the saline or salt water in two streams. One is fresh water stream for drinking and farming and the other contains dissolved salts.
The setting up of a desalinated plant is very demanding and costly and the running cost is also huge. It takes a lot of energy and resources to set up and run a desalinated plant.
Thus in the context, the village would not be able to afford a desalination plant.
