I believe the answer is C. motivation.
Sorry what is your question I got confuse you want to now if they are synonymous
2, 4, and 5 have to be the answer by process of elimination
Edit: 4 "he followed out his original design," is incorrect but 2 "Endowed with commonsense, as massive and hard as blocks of granite" and 5 "On the score of delicacy, or any scrupulousness which a finer sensibility might have taught him, the Colonel, like most of his breed and generation, was impenetrable." are.
Happiness comes now and then,
Were not sure when,
But when its here enjoy every minute of it,
Because happiness has so much power,
It brings joy to everyone,
What peace of mind happiness can show,
Forget the troubles of the past.
Never fear that it will go for it could always grow
and tomorrow there it will be,
For happiness can set you free!
