<em>Adjectives</em><em> in Spanish.</em>
Adjectives in Spanish have the peculiarity that they have gender (male or female) and number (singular or plural), in the vast majority of cases. An example of this can be done with the adjective "calvo" given in the exercise:
<em>Calva:</em> female and singular.
<em>Calvas:</em> female and plural.
<em>Calvo:</em> male and singular.
<em>Calvos: </em>male and plural.
Therefore, <u><em>first the gender and number of the </em></u><u><em>noun</em></u><u><em> that the adjective will characterize must be identified</em></u>, in order to use an adjective with the same characteristics.
On the other hand,<u><em> the adjective in Spanish is usually placed after the noun</em></u>, unlike in English, with some exceptions such as: "mucho, varios."

To understand this answer we need to make a summary of the legend. First of all, it is about a couple of lovers. She is the daughter of a wealthy businessman while he is just a mine worker. Then her father menaced to arrange a marriage with an old rich Spanish businessman if they didn't give up their love. After that Carlos, her former lover found out where she lived and bought the house next to hers. Then, they saw each other in their balconies. One day he kissed her and Carmen's father killed her, he then killed himself. That is the legend. Nothing supernatural occurred there.
