The correct answer is: A. How does changing the amount of water affect the growth of corn?
While options B, C & D are not impossible to test, option A is the only question that can be tested using quantitative methods, such as statistical analysis. The question in option A states: "How does changing the amount of water affect the growth of corn?". This question is easily testable using scientific investigation, because controlled or measured amounts of water can be added to corn, and the consequent growth rate of corn can be easily measured and recorded. However, the questions in options B, C & D cannot be precisely measured using quantitative tools, since they aim to measure qualitative (subjective) factors, such as: ethics, happiness and disappointment.
Answer:
The carrying ability of an ecosystem is the overall growth rate of a biological species that can be supported by that area, provided the available food, habitat, water, and other resources.
Explanation:
A pond populated briefly by ten turtles, for such, would be sustainable for the species' population.

Hurricanes (also known as typhoons or cyclones, depending on the location on Earth where they form) are often associated with extremely powerful winds and torrential rains. I am not sure about the pressure, but the only option here that mentions both strong winds and a lot of rain is A. low pressure, high winds, high precipitation, so I'd say that is the correct answer.
