It would be more accurate to say that maturation:

یہ کہنا زیادہ درست ہوگا کہ پختگی:

Can be delayed by illness or poor nutrition

Is dramatically accelerated by good nutrition

Is not affected by any environmental factors because it is genetic

Is greatly accelerated by good health care and delayed by illness

It would be more accurate to say that maturation is greatly accelerated by good health care and delayed by illness

یہ کہنا زیادہ درست ہوگا کہ صحت کی اچھی دیکھ بھال سے پختگی بہت تیز ہوتی ہے اور بیماری کی وجہ سے تاخیر ہوتی ہے۔
