First, you have to know that dropping out at highschool can make finding a good paying job more difficult, unless you have a valid certificate. I think that you can become this way a:
- carpenter (diploma don't needed)
- construction manager
- Mechanic
C because once you start you finish, also could be skipped if she was concerned about a heart attack
I'd have to say d. the hand, because every human (for the most part, no offence intended to anyone) has a hand and is able to make good (or bad, rather) use of it. It's what a person always has access to at any given time or place, even if they don't have access to one of the other options.
