Input: Consider Input: This means that in a closed system of particles, there are no internal forces that are unbalanced. That is, the action-reaction force shared between any two objects in a closed system will not cause the center of mass of the system to accelerate. The constituent objects only accelerate with respect to each other, the system itself remains unaccelerated. Alternatively, if an external force acts on the system, then the center of mass will experience an acceleration proportional to the magnitude of the external force divided by the mass of the system.:19-1

Output: What experiences acceleration when external force is applied to a system?


Input: Consider Input: After the watershed events of Hurricane Andrew in 1992, the state of Florida began investing in economic development through the Office of Trade, Tourism, and Economic Development. Governor Jeb Bush realized that watershed events such as Andrew negatively impacted Florida's backbone industry of tourism severely. The office was directed to target Medical/Bio-Sciences among others. Three years later, The Scripps Research Institute (TSRI) announced it had chosen Florida for its newest expansion. In 2003, TSRI announced plans to establish a major science center in Palm Beach, a 364,000 square feet (33,800 m2) facility on 100 acres (40 ha), which TSRI planned to occupy in 2006.

Output: What did Hurricane Andrew cause Florida to do 


Input: Consider Input: After the death of the replacement bishop Gregory in 345, Constans used his influence to allow Athanasius to return to Alexandria in October 345, amidst the enthusiastic demonstrations of the populace. This began a "golden decade" of peace and prosperity, during which time Athanasius assembled several documents relating to his exiles and returns from exile in the Apology Against the Arians. However, upon Constans's death in 350, another civil war broke out, which left pro-Arian Constantius as sole emperor. An Alexandria local council in 350 replaced (or reaffirmed) Athanasius in his see.
Output: Who did he have to thank for his ability to come back to Alexandria in 345?
