Explanation:

In spanish, adjectives must coincide in gender and number with the noun.In this case, the noun is plural, and masculine (because Maia y Samuel can be changed by "ellos", which is a plural noun used in all the cases that are not feminine plurals).Then, between the plurals adjectives (atrevidos and atrevidas) we chose the first one, because we are not talking about two females, but about a man and a woman.Note that, in every case where plurals are formed both by men and women (like this case), the plural adjective takes the form of a masculine plural.
