Which of the following is not a reason why infectious diseases like malaria and hiv/aids often hamper economic development? a. life expectancy begins to rise. b. caregivers lose time at work. c. more tax dollars are shifted to health care. d. people have difficulty working and earning income.

The correct answer is - A. Life expectancy begins to rise.

In the countries where the malaria and HIV/AIDS are very common, big portion of the population is struggling to survive, as it is not able to perform any job properly, the energy is not there, the body is becoming weaker. The life expectancy is also kept pretty low because of these two diseases, so lot of people die between their 20's and 40's, practically in their prime years. That affects the economic development heavily, as lot of people at working age are either not able to work, or are dying. Also, lot of children are born with these diseases, and big portion of them die before they reach adulthood.

the answer is b. hope this !
