Technological advances have had a marvelous impact on human lives and have had nearly no detrimental effects.

a. True

b. False

False, there are many reasons on how it caused detrimental effects. like the invention of the machine gun for example or the nuclear bomb.

I would say B. false.

Technological advances, while having positive effects on health, have also had detrimental effects on health. Advances have also cause an over-reliance on technology which can be viewed as detrimental. Furthermore, advances have impacted our mental health and the way our brain and memory work in a negative way. There are several more opinion based reasons that someone could have for this answer (including cyber bullying, cyber crime, weapons, etc.).

I can't promise you this is the correct answer. This is an opinion based question because each person will have a different opinion on what "nearly no" means.
