Data related to the past 30 years reveals some interesting insights about the propensity of a country to go into a war. Over the past 30 years, the countries that maintained the highest military strengths were also more aggressively involved in a higher number of wars. Moreover, the likelihood of getting aggressively involved in a war increased for countries whose military strength increased significantly during this period. Since there was no major world-wide war phenomenon in the recent past, it is likely that an increased military strength causes the increase in aggressive behavior and the higher involvement in wars.

Which of the following, if true, most strengthens the argument?

A.The data doesn't distinguish between the countries that were consistently involved in war and the countries that were involved in more wars during the beginning and end of the 30-year period.
B. Some countries cited in the data were rarely involved in any war
C.Data shows that none of the countries that had zero increase in military strength showed any increase in their involvement in wars.
D.Situations that trigger an increase in military strength such as political tensions with neighboring countries are also likely to increase a country's propensity to become involved in wars.
E.Data related to some of these countries is available only for a partial duration out of the 30-year period
