Final answer:
The definite article 'los' should be changed to 'las' to agree with the noun 'profesoras'.
Step-by-step explanation:
The definite article 'los' is used to indicate a plural masculine noun in Spanish. However, the noun 'profesoras' is plural feminine. In Spanish, there needs to be agreement between the definite article and the noun in terms of gender and number. Therefore, the correct form should be 'las profesoras'.
