Women should not serve in the military in active duty combat roles because women cannot perfonn allof thesarne ptrysical tasks that men can. Because rnen are genetically larger and stronger, only men should be allowedto participate in active duty combat roles.

7. The average math score on statewide proficiency exam for students attending Middlebury High School last year was20 points higher than the average math score for students attending nearby Ellingsford High School.

test got scores that are at least 20 points higher than the average score at Ellingsford High School.(B) Middlebury High School students who transfer to Ellingsford High School in the summer before they take

the proficiency exam get average scores that are comparable to the average scores of students who remain atMiddlebury.

(C) Middlebury High School offers its students a unique, weeklong course just before they take the proficiency' exaln that has consistently proven effective in raising student scores.(D) In the past five years, the average score at Ellingsford High School has been rising at a faster rate than has

the average score at Middlebury High School.(E) Students wanting better proficiency exam scores are transferring to Middlebury High School at a high rate,

which will ultirnately result in a lowering of the school's average score.
