Discuss the significance to intellectual development of two key individuals, each from a different region.

The question requires that candidates offer a considered and balanced review of the significance of two key individuals to intellectual development. While the two individuals must be from different regions, they may or may not have been contemporaries. A comparative approach may or may not be used. Candidates may refer to the individuals’ significance in a variety of ways, for example, the proposal of new scientific theories or the contribution of inventions that affected the spread of knowledge. Discussion of their significance may extend beyond the timeframe provided there is a clear link back to the individual(s). While other relevant factors may be referred to, for example the wider advances in science and technology, the bulk of the response will remain on the issue raised in the question.
