The students who had the flu had a(n) _____ reason for missing school. They normally have perfect attendance, and their absence
that day was a(n) _____ A. unjustifiable … travesty
B. legitimate … aberration
C. unwarranted … anomaly
D. sensible … farce
E. inconsolable … fluke
I crossed out C, D, and E so far.
The answer is B. Because, if the students had the flu, of course their absence was 'legitimate', which means 'acceptable', allowed. And 'aberration' means 'something unusual or unexpected", because they usually have perfect attendance, but now they missed a couple of classes.
