For which of the following situations is a special exposure cohort MORE LIKELY TO BE PREFERRED over a general exposure cohort?

Please look at the table below for the questions. Each question has its individual points. The following table shows a 2X2 table data from an epidemiological study.    Exposure Status  Disease Status Person-years at risk Present (Yes, exposed) 700 1950 Absent (No, not exposed) 300 2250 (Same figure as above)     1. What type of study was this most likely to be? (2 points) 2. What is the incidence rate among those who are exposed to the factor under study? (3 points)  3. What is the incidence rate among those who are not exposed to the factor under study? (3 points) 4. What is the rate difference? (2 points)      

The following tables are the descriptive tables from a case-control study.( Tariku MK, Belete AH, Worede DT, Tegegne BA, Bante SA, Misikir SW. Measles Outbreak Investigation in Aneded District, Northwest Ethiopia: A Case-Control Study. J Epidemiol Glob Health. 2024 Sep;14(3):1231-1241. doi: 10.1007/s44197-024-00279-5. Epub 2024 Aug 1. PMID: 39088155; PMCID: PMC11442813.) Based on your experience with doing homework assignment using person, place and time concept, describe the data provided in the two tables below. This question is worth 10 points.  The Kebeles are the smallest administrative unit of local government, roughly equivalent to a neighborhood, ward, or municipality.    Table 2: Epi curve shows the distribution of measles cases by date of onset of signs and symptoms in Aneded district, Northwest Ethiopia, 2020
