The correct answer is drift
Continental drift is a theory that initially postulated the movement of continental masses over the Earth's geological time, considering that, previously, the current continents had other forms and even were located in other locations on the planet. These observations were made even before the knowledge about the tectonic plates, which served as a further proof of the movement not only of the terrestrial continents, but of the entire crust.
The theory of continental drift emerged a long time ago, since since the mapping of some points on Earth, it was suspected that the continents were previously united. Francis Bacon, in 1620, suggested, for example, that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had separated in the remote past. A similar observation to this had already been made by Abraham Ortelius, in 1596.

Answer:
The answer is Jerusalem and Palestine remained under Christian control only sporadically and in certain cities during the Crusades.
Explanation:
During the Crusades, Jerusalem was conquered by the Christians in the First Crusade in 1099, but it was then conquered by the Ayubbids in 1187. It wasn't renegotiated back to Christian control until the Sixth Crusade, only to be lost again to the Khwarazmian dynasty in 1244. The population of Palestine was mostly Christian until 1187 when a Sunni Muslim of Kurdish origin named Saladin took Palestine (and Jerusalem) becoming the Sultan of Egypt and Syria and wrestling Palestine from the Crusaders at the Battle of Hattin.
Research on brain activity shows that by taking pictures and engaging in other activities, Ashely's brain activity for driving has reduced by d. 37%.
<h3>Why would her brain activity decrease by this amount?</h3>
