A verb is an action. Such as run, read, breath, etc
So, the verb in this sentence is "take"
Underestimating people is a huge mistake. Often, those who appear to be innocent are everything but.
I would want to rest and do things I want to do. If you take and arrange everything in advance then you will worry if you have everything or not. I would want to watch Tv and hang out with friends. There is a lot more to life than organizing stuff and waiting for that something to happen. Relax and enjoy yourself.
The first are true the last are false sorry if this doesn't help :(
