The image shows a page from a textbook with handwritten annotations. The textbook appears to be in Chinese and discusses research methods, likely in the field of epidemiology or public health, as indicated by terms like "暴露" (exposure), "疾病" (disease), "相对危险度" (relative risk), and "队列研究" (cohort study). The annotations consist of checkmarks, crosses, and numerical calculations, suggesting that someone has been working through practice problems. Some of the questions are numbered 12 through 17. There are also some lettered options (A, B, C, D, E) for each question, and some of these options have been circled or marked. There is no information within the image to suggest a location in the city of Chongqing High-tech Zone, China. The image is a close-up of a book page and does not provide any environmental context.
