A population of starlings started at 274, and had an annual natality rate of 6/year, a mortality rate of 13/year, an immigration rate of 39 year, and an emigration rate of 92 year. The size of the population at the end of the first year would be:
О 214 starlings
O 274 starlings
424 starlings
O 548 starlings
