Passage Summary: Even though the number of incoming chemistry students is steady and the job market for them is excellent, the number of people actually graduating with chemistry degrees has dropped.

Reasoning: N/A

Analysis: We are looking for a 'missing link' that explains why students are failing to cross the finish line. Since the 'input' (new students) and the 'incentive' (jobs) are both strong, there must be an internal obstacle within the university process. A helpful explanation might suggest that the curriculum has become significantly more difficult, or perhaps a different, more attractive major is poaching these students before they graduate. Focus on finding a factor that specifically impacts the completion rate of the degree.
