[EX Q]: proper question: When did Ronald Robinson die?
disfluent question: How did or no make that when did Ronald Robinson die?
context: During the 20th century, historians John Gallagher (19191980) and Ronald Robinson (19201999) constructed a framework for understanding European imperialism. They claim that European imperialism was influential, and Europeans rejected the notion that imperialism required formal, legal control by one government over another country. In their view, historians have been mesmerized by formal empire and maps of the world with regions colored red. The bulk of British emigration, trade, and capital went to areas outside the formal British Empire. Key to their thinking is the idea of empire 'informally if possible and formally if necessary.'[attribution needed] Because of the resources made available by imperialism, the world's economy grew significantly and became much more interconnected in the decades before World War I, making the many imperial powers rich and prosperous.

[EX Q]: proper question: Why did student applications increase during the 1950s?
disfluent question: Why did the university applicants decrease no rather tell me why student applications increased during the 1950s?
context: In the early 1950s, student applications declined as a result of increasing crime and poverty in the Hyde Park neighborhood. In response, the university became a major sponsor of a controversial urban renewal project for Hyde Park, which profoundly affected both the neighborhood's architecture and street plan. During this period the university, like Shimer College and 10 others, adopted an early entrant program that allowed very young students to attend college; in addition, students enrolled at Shimer were enabled to transfer automatically to the University of Chicago after their second year, having taken comparable or identical examinations and courses.
