I can't not find a right word. Let's say, we are discussing about how to protect our children from harming themselves. And a person says like we can lock all the windows in the school to make the environment safe. OR, You've been seeing a doctor for a while for a constant pain that doesn't go away. When you complain about why the pain persists for so long, the doctor says like Okay I will give more pain killers. But, these suggestions above are quite..non-sense, right? They are not getting to the bottom of the problems. So, I want to say "That can't be a *** solution. The only word that I can think of is "fundamental" But I am not sure if this word would work for the latter situation above. Could anyone help me?
