easy · LSAT Logical Reasoning
To earn an 'A' in the chemistry course, a student must score at least 90 percent on the final exam. Jordan scored a 92 percent on the final exam. Therefore, Jordan earned an 'A' in the course.
The reasoning in the argument is questionable because it
- treats clearing a threshold that the grade requires as though clearing it were enough to secure the grade.
- assumes the single final-exam score fairly reflects the quality of Jordan's graded work across the whole term.
- fails to spell out the precise method by which Jordan's reported 92 percent final-exam score was computed.
- takes for granted that not one of Jordan's many classmates managed to score any higher on the same final.
- presumes that surpassing the 90 percent mark is flatly impossible for a student who has not mastered the material.
