Step-by-step explanation:
Trialability refers to the ease with which potential consumers can test or try a new product before making a purchase decision. By providing samples to potential consumers in Madrid, Fiona is reducing the degree of economic and/or social risk associated with product use.
This allows potential consumers to experience the benefits and features of the product firsthand, increasing their confidence in the product and reducing their perceived risk.

This helps reduce their uncertainty about the product's effectiveness, potentially increasing their willingness to adopt the new brand.
