Answer:
I) George is correct
Reason: Sound waves, an example of mechanical wave is only longitudinal NOT tranverse
Explanation:
The difference is that the direction of a tranverse wave is perpendicular to the direction of vibration unlike the direction of a longitudinal wave that is same as the direction of the vibration.
Also examples of mechanical waves are water waves (tranverse) and sound waves (longitudinal). Thus GEORGE IS CORRECT having stated that "sound waves were longitudinal and not transverse" unlike sally who made a non-specific statement

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.
