[EX Q]: Question: Once a member of the Birmingham Repertory Theatre, what was Derek Jacobi's first action role? Passage:While in the sixth form, he starred in a production of Hamlet, which was taken to the Edinburgh Festival Fringe and very well regarded. At 18 he won a scholarship to the University of Cambridge, where he read history at St John's College and earned his degree. Younger members of the university at the time included Ian McKellen (who had a crush on him—"a passion that was undeclared and unrequited", as McKellen relates it) and Trevor Nunn. During his studies at Cambridge, Jacobi played many parts including Hamlet, which was taken on a tour to Switzerland, where he met Richard Burton. As a result of his performance of Edward II at Cambridge, Jacobi was invited to become a member of the Birmingham Repertory Theatre immediately upon his graduation in 1960.

[EX Q]: Question: Who is the current mayor of the city located on the northern Great Plains that the Yellowstone River flow through? Passage:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.
