Explanation:

The camel caravans which crossed the great dunes of the Sahara desert began in antiquity but reached their golden period from the 9th century CE onwards. In their heyday caravans consisted of thousands of camels travelling from North Africa, across the desert to the savannah region in the south and back again, in a hazardous journey that could take several months. Stopping along the way at vital oases, the caravans were largely controlled by the Berbers who acted as middlemen in the exchange of such desired commodities as salt, gold, copper, hides, horses, slaves, and luxury goods. The trans-Saharan trade brought with it ideas in art, architecture, and religion, transforming many aspects of daily life in the towns and cities of a hitherto isolated part of Africa.

answer; /// i believe that the correct answer is(cognitive revolution);

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
