Answer:
Foreign country helps Italy in its unification.
Explanation:
The Kingdom of Piedmont that is located in northern Italy defeat Austria and gain control of unification efforts across Italy because Italy was unable to defeat Austria and unify all its states. Italy would not be able to achieve independence or unity without foreign help so due to the help of Kingdom of Piedmont in the defeat of Austria, Italy was able to unify the country which was captured by Austria so we can say that foreign country helps Italy in its unification.
