I needed the answer
To find the missing word, we can analyze the given options: increased birth rate, increased _____________, or immigration.
We are looking for a word that corresponds to the idea of an increase in population. From the given options, "increased birth rate" and "immigration" both contribute to population growth. Therefore, the missing word should also reflect an increase in population, specifically related to the lifespan.
Thinking logically, if people are living longer, it would contribute to an increase in population as individuals are not dying at the same rate. Combining this with the options provided, the missing word is "increased life span."
