Final answer:
The correct conjugated verb for the sentence is 'practicamos'.
Step-by-step explanation:
The correct conjugated verb to fill in the blank is practicamos.
This verb form is used because the subject 'Julio y yo' is first-person plural, which means 'we' in English. 'Practicamos' is the correct conjugation of the verb 'practicar' for this subject pronoun.
For example, the sentence 'Julio y yo practicamos fútbol después de la escuela' means 'Julio and I practice soccer after school.'
