Ex Input:
Passage: In the late 19th and early 20th century several forms of pragmatic philosophy arose. The ideas of pragmatism, in its various forms, developed mainly from discussions between Charles Sanders Peirce and William James when both men were at Harvard in the 1870s. James popularized the term "pragmatism", giving Peirce full credit for its patrimony, but Peirce later demurred from the tangents that the movement was taking, and redubbed what he regarded as the original idea with the name of "pragmaticism". Along with its pragmatic theory of truth, this perspective integrates the basic insights of empirical (experience-based) and rational (concept-based) thinking.

Ex Output:
What year did Charles Sanders Peirce graduate from harvard?

Passage: In the beginning, the Quran did not have vocalization markings. The system of vocalization, as we know it today, seems to have been introduced towards the end of the ninth century. Since it would have been too costly for most Muslims to purchase a manuscript, copies of the Quran were held in mosques in order to make them accessible to people. These copies frequently took the form of a series of 30 parts or juzʼ. In terms of productivity, the Ottoman copyists provide the best example. This was in response to widespread demand, unpopularity of printing methods and for aesthetic reasons.

Ex Output:

In which century were vocalization marking taken from the Quran?
