What effect can better health facilities have on death rate?

Correct answer: The death rate may decrease

The correct answer is A: better health facilities may reduce the death rate. Health facilities include access to doctors, hospitals, medicines, vaccinations, emergency treatment, maternal care, and disease prevention. These services can help prevent or treat illnesses and can save lives, so fewer people may die during a given period. Option A is correct because it gives the likely possible effect without saying it is guaranteed in every situation. Option B is wrong because improved healthcare generally works to prevent avoidable deaths rather than increase them. Option C is wrong because health services do not stop births; births are related to fertility and reproductive decisions. Option D is wrong because migration is movement between places and is not automatically reduced to zero by better healthcare. Other factors, such as nutrition, sanitation, age structure, and disease conditions, also influence death rate. Memory cue: better care can reduce deaths, but it does not directly control migration or births.
