A rise in thepercentage of all 18-year-olds who were recruited by the armed services of asmall republic between 1980 and 1986 correlates with a rise in the percentageof young people who dropped out of high school in that republic. Since18-year-olds in the republic are generally either high school graduates or highschool dropouts, the correlation leads to the conclusion that the republic’srecruitment rates for 18-year-olds depend substantially on recruitment ratesfor high school dropouts.
Which one of thefollowing statements, if true, most weakens the argument?
(A) A large numberof 18-year-old high school graduates were recruited for the republic’s armedservices in 1986 than in 1980.

(C) Between 1980and 1986 the percentage of high school graduates among18-year-olds recruited in the republic rose sharply.
(D) Personnel ofthe republic’s armed services are strongly encouraged to finish their highschool education.
