    【Question】
    Compute the average score of the university located in Brazil. average score refers to avg(score); located in Brazil refers to country_name = 'Brazil';

    【Evidence】
    average score refers to avg(score); located in Brazil refers to country_name = 'Brazil';

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT AVG(T2.score) FROM university AS T1 INNER JOIN university_ranking_year AS T2 ON T1.id = T2.university_id INNER JOIN country AS T3 ON T3.id = T1.country_id WHERE T3.country_name = 'Brazil'
