Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.

The man who is perpetually hesitating which of the two things he will do first, will do neither. The man who resolves, but suffers his resolution to be changed by the first counter-suggestion of a friend, - who fluctuates from opinion to opinion, from plan to plan, and veers like a weather-cock to every point of the compass, with every breath of caprice that blows-can never accomplish anything great or useful. Instead of being progressive in any thing, he will be at best stationary, and more probably retrograde in all. It is only the man who first consults wisely, then resolves firmly, and then executes his purpose with flexible perseverance, undismayed by those petty difficulties which daunt a weaker spirit that can advance to eminence in any line. Take your course wisely, but firmly; and having taken it, hold upon it with heroic resolution, and the Alps and Pyrenees will sink before you.
