Ans: A workman blames his bad tools.
(C)wife, children, and, he, his, care, takes, of

Question

Answer

1. How sweet this rose smells! 
(It's an exclamation.)

2. A bad workman blames his tools.

Funnily enough, what you wrote is actually a correct sentence but 'a bad workman blames his tools' is an expression and I would wager what the answer scheme is looking for.

3. Correct.
