Question

how did the administrative division of the roman empire contribute to its decline? the division between east and west weakened mutual support and made the western empire more vulnerable. the division between east and west eliminated all external threats. the division between east and west strengthened the western empires military. the division between east and west led to immediate reunification.

Explanation:

The administrative division of the Roman Empire into East and West meant that resources and support were split. The Western Empire, facing more barbarian - related threats, did not have the full - scale support of the East, making it more vulnerable and contributing to its decline. The other options are incorrect as the division did not eliminate external threats, did not strengthen the Western Empire's military, and did not lead to immediate reunification.

Answer:

The division between East and West weakened mutual support and made the Western Empire more vulnerable.
