They give you all the explanation I would have in the first paragraph before the questions, so hopefully these examples help! :)
3: The innovation has been amazing since it was done so well, so I have no worries for the future of my house.
4: I am careful where I stored my retainer because my dog might get to, yet I am still worried it may be chewed up.
5: It was beyond my power to help subsidize my brother's business so my mom offered to help, but she could not either.
6: I took a map with me because the edifice was huge, but I somehow got lost still.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
