Answer: Three
Explanation:
In the lecture on Population change in Bangladesh by Hans Rosling, he speaks on how there is a transformation in Bangladesh as more families move towards smaller families and a general welfare in population.
He then shows how one of the factors behind this transformation is an improvement in child survival using an example of how three of Hanan's siblings had died from measles but might have survived if there was a doctor present.
With vaccines, treatments of infections and better nutrition however, more children now survive.
