After which event did Christians start to learn more about Muslim advances in science and mathematics?

A) Crusades

B) Battle of Tours

C) Thirty years war

D) Battle of Hastings

B) Battle of Tours

Explanation:

The Battle of Tours, fought in 732 AD, stopped the Arabic expansion in Europe, after a wave of Arabic conquests had taken Spain. After Spain, the next logical target was France. Had the Arabs won a victory at Tours, Islam would have surely spread in Europe. But Christian armies managed to defeat the Muslim intruders and made them retreat. So, Muslim, Arabic presence was confined to Spain until the 15th century, where Córdoba and Granada became centers of learning. Academic and intellectual exchanges between Arabs in the Iberic Peninsula and Christian Europe took place and allowed the latter to recover classic Greek culture, for example.
