Which is an advantage that crops may attain through genetic engineering? modifying pests surviving droughts growing organically maturing longer

Correct Surviving in drought

A genetically modified organism is an organism whose DNA is altered or manipulated by the means of genetic engineering. In most case it is altered by incorporating a part of other organism DNA with the help of plasmid which carry gene from one organism to another.

Genetically modified crops are modified for better health benefits, crop resistant, drought resistance property which enable plants to survive under extreme conditions.

Example of genetically modified crops: Biofortified soya beans, golden rice  

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
