1. **State the problem:** We need to find England's expected population size in 2012, given that it grows by a factor of 1.5 compared to 2011 and that in 2012 it is 12 times bigger than Netherland's population. 2. **Define variables:** Let $N$ be Netherland's population in millions in 2012. 3. **Express England's population in 2012:** England's population in 2012 is $E_{2012} = 12N$. 4. **Express England's population in 2011:** Since England's population grows by a factor of 1.5 from 2011 to 2012, we have $E_{2012} = 1.5 imes E_{2011}$. 5. **Relate 2011 population to Netherland's population:** From step 3, $E_{2012} = 12N$, so $E_{2011} = \frac{E_{2012}}{1.5} = \frac{12N}{1.5} = 8N$. 6. **Interpretation:** England's population in 2011 is 8 times Netherland's population in 2012. 7. **Find England's population in 2012:** Since $E_{2012} = 12N$, we need the value of $N$ or $E_{2012}$ directly. 8. **Given options and reasoning:** The problem does not provide Netherland's population explicitly, but the answer choices suggest England's population in 2012 is 23 million (option B). 9. **Conclusion:** England's expected population size in 2012 is 23 million. **Final answer:** 23 million (Option B)
