the hyksos had a huge impact on new kingdom Egypt. Not only did they introduce new technology such as the loom, the chariot and the composite bow, but they more importantly expanded Egypt's previously narrow minded foreign policy. After the expulsion of the Hyksos Egypt established a permanent professional army. With Thutmose the first the beginnings of Egypt's vigorous expansionist policy is initated. The Hyksos also introduced the concept of foreign trade to the Egyptians, such as sthe expedition to Punt, nth Africa, levant, the mediterranean etc etc. Nubia can also be included in this. Just find how Egypt has changed from the Expulsion of the Hyksos then build an argument to support whatever points you make. Within reason of course.... does that solve your problem?
