The problem statement contains contradictory information. Contradiction Analysis: 1. The diagram shows two circles. Let's call the larger left circle "Circle 1" and the smaller right circle "Circle 2". 2. Points C, D, E, F lie on Circle 2. 3. D_2 refers to CDE. This is an inscribed angle in Circle 2 that subtends arc CE. 4. F_1 refers to EFC. This is also an inscribed angle in Circle 2 that subtends arc CE. 5. According to the theorem "Angles subtended by the same arc in the same circle are equal", CDE and $
