Which three parts of this excerpt from Nathaniel Hawthorne's novel The House of Seven Gables provide direct characterization? Had he been told of a bad air, it might have moved him somewhat; but he was ready to encounter an evil spirit on his own ground. Endowed
with commonsense, as massive and hard as blocks of granite, fastened together by stern rigidity of purpose, as with iron clamps, he followed
out his original design, probably without so much as imagining an objection to it. On the score of delicacy, or any scrupulousness which finer
sensibility might have taught him, the Colonel, like most of his breed and generation, was impenetrable. He therefore dug his cellar, and laid the
deep foundations of his mansion, on the square of earth whence Matthew Maule, forty years before, had first swept away the fallen leaves. It
was a curious, and, as some people thought, an ominous fact, that, very soon after the workmen began their operations, the spring of water,
above mentioned, entirely lost the deliciousness of its pristine quality.

In my opinion, these two answers provide a direct characterization in the best manner:

1. Endowed with common sense, as a massive and hard as blocks of granite,

2. 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.

Explanation:

Endowed with reasonable, as huge and onerous as blocks of granite, mounted along by stern rigidity of purpose, like iron clamps, he followed out his original style, most likely while not such a lot as imagining an objection thereto. On the score of delicacy, or any scrupulousness that a finer sensibility may need educated him, the commissioned military officer, like most of his breed and generation, was impenetrable."

This half provides direct characterization.

Direct characterization is wherever the talker tells the reader concerning the character. The talker specifically told the readers the traits of the commissioned military officer. Traits like invested with sense, as huge and hard, The commissioned military officer was impenetrable.

b is the answer.   i sat on the lumpy sofa, totally exhausted, with a bad taste in my mouth, wondering what i should do next.  

the economic activity signified in that scenario is a. production

there is no money exchange involved in distribution, generalized reciprocity or balanced reciprocity.
