2. Question: What contribution from the Gupta Empire was eventually adopted by both the Arabs and the Europeans?
a. their long epics
b. their number system
c. their songs and music
d their elaborate structures

B, their number system.

Explanation:

The Arabic Number system (1,2,3,4,5,6- Numbers like these.) was created in India and later adopted by Arabs. The reason they call it Arabic, is because the Europeans were introduced to it from Arabs and not Indians, so they assumed Arabs made it.

this is true

map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. for example, on a 1: 100000 scale map, 1cm on the map equals 1km on the ground.
