Question

what was not a modern advantage that allowed imperialism to happen?
new medicines
alliances with other nations
railroads
steamships
the telegraph
rewatch

Explanation:

To determine which was not a modern advantage for imperialism, we analyze each option:

• New Medicines: Helped imperialists survive diseases in colonized areas, aiding imperialism.
• Alliances with other nations: Imperialism was more about a nation's direct expansion (colonies, resources) rather than relying on alliances as a "modern advantage" for its occurrence. Imperial powers often competed, and alliances were more for power - balancing in conflicts, not a core advantage enabling imperialism's expansion (like technology or medical advances).
• Railroads: Facilitated movement of goods, troops, and communication in colonies, aiding imperialism.
• Steamships: Enabled faster long - distance travel for trade, military, and colonization.
• The telegraph: Improved communication, helping imperial administration.

Answer:

B. Alliances with other nations
