Question

two reasons that paved roman roads were one of the most important technological advantage include a easy access for trade and commerce and better sanitation. b better troop transportation and easy access for trade and commerce. c water traveled to towns and cities faster and better troop transportation. d water traveled to towns and cities faster and easy access for trade and commerce.

Explanation:

Roman roads were crucial for better troop transportation (to move armies quickly across the empire) and easy access for trade and commerce (facilitating movement of goods and people). Option A mentions sanitation which is more related to aqueducts, and options C and D mention water travel which is not the main purpose of Roman roads (water travel is via rivers/seas, roads are land - based). So option B is correct as it aligns with the known purposes of Roman roads: improving troop movement and enabling trade/commerce.

Answer:

B. better troop transportation and easy access for trade and commerce.
