How does illiteracy help to increse population growth rate

I don't know the answer but thank you for free points and I really needed this point so that I can ask some question from anyone

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth
