Question

what advantage did tanks offer in world war i?
armored protection and ability to move in difficult terrains
greater visibility and clearer mapping of enemy territory
improved communication and coordination between units
the ability to safely retrieve wounded soldiers from the front line

Explanation:

To determine the advantage of tanks in WWI, we analyze each option:

• Tanks had armor for protection and could traverse difficult terrains (like trenches, mud) that infantry struggled with.
• "Greater visibility..." is incorrect as tanks didn’t aid in mapping/visibility.
• "Improved communication..." is not a tank - specific advantage.
• "Retrieve wounded..." was not a primary tank function (medics/ambulances were for that). So the correct option is the one about armored protection and terrain movement.

Answer:

A. armored protection and ability to move in difficult terrains
