Given the fact that food manufacturers have to abide by food safety guidelines, do you think our taste buds are obsolete?

The answer is false. It is because the way the food manufacturers abide food safety guidelines or how they manufacture food will affect a person's taste buds. Obsolete means out of date-- which, will not happen to our taste buds as it does not involve in how the manufacturers dealt with the food and makes our taste buds turn to out of date or have it less developed.

No that answer is wrong. you have written the function of mitochondria in chloroplast and function of chloroplast in mitochondria.
