Utilizing sensory analysis tools in the evaluation of product differences, evaluate the following statements:

I- The paired comparison method, in addition to indicating whether or not a detectable difference exists, also informs the magnitude of that difference.
II- Using the duo-trio method, the taster evaluates three samples, one marked as a reference and the other two randomly coded.
III- In the triangular method, the taster receives three distinct samples, must evaluate them, and determine which sample has the highest intensity of the evaluated attribute.
IV- The results of the multiple comparison method can identify whether there is a difference between the samples, as well as their magnitude, being efficient for evaluating four or five samples at the same time.

Is only correct what is stated in:

I- The paired comparison method, in addition to indicating whether or not a detectable difference exists, also informs the magnitude of that difference.
II- Using the duo-trio method, the taster evaluates three samples, one marked as a reference and the other two randomly coded.
III- In the triangular method, the taster receives three distinct samples, must evaluate them, and determine which sample has the highest intensity of the evaluated attribute.
IV- The results of the multiple comparison method can identify whether there is a difference between the samples, as well as their magnitude, being efficient for evaluating four or five samples at the same time.
