Final answer:
In order to achieve more success in post-independence Latin America, liberals could have pursued a more radical political agenda, advocating for progressive policies and social reforms.
Step-by-step explanation:
In order to achieve more success in their goals in post-independence Latin America, liberals could have pursued a more radical political agenda. By advocating for progressive policies and social reforms, liberals could have addressed the social and economic inequalities that persisted after independence. They could have focused on implementing land reform, promoting worker's rights, and improving education and healthcare systems.
Forming stronger alliances with conservative groups may not have been effective as conservatives often opposed liberal policies and reforms. Embracing authoritarian leadership would have contradicted the principles of democracy and self-governance that liberals fought for during the independence struggles. Advocating for a return to colonial rule would have negated the entire concept of independence and undermined the aspirations of the Latin American people.
