The use of the phrase "great works on heredity" serves which of these purposes in the passage?

It provides a clear indication about Dr. Pascal's career.

Explanation:

Émile Zola's novel "Doctor Pascal" is from the Rougon-Macquart series, with it being the final novel of the series. The story revolves around themes of heredity and follows the protagonist Dr. Pascal and his life of practicing his profession.

In the given passage from the initial stage of the story, we are given the description of the room, Doctor Pascal's study. This room has cupboards and tables full of books, papers, etc. from his case studies and experiments from "more than thirty years" which include "[his] great works on heredity."

Thus, the use of this phrase gives the impression of how long or how vast the collection of papers was and thus, provides the immense 'proofs' of his career, Doctor Pascal's career. Through all these "papers and manuscripts of all sorts, piled up in confusion and filling every shelf to overflowing", we are given an insight into what the doctor's career likely is.

Thus, the correct answer is the third option.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.

"the monkey's paw" is a rare story in that the theme is actually stated in the story. sgt. maj. morris tells the whites that the old fakir who put the spell on the paw said, "fate rules people's lives and those who interfere with fate do so to their sorrow." the message is a warning, but mr. white doesn't believe it. even though sgt. maj. morris makes it clear that he tried wishing with unfortunate results and he tries to throw the paw on the fire,   mr. white makes a wish for 200 pounds only to find that he receives the money when herbert dies in a factory accident. according to the fakir, then, because mr. white had wished for something he should not have had, his son lost his life.

the second wish that mrs. white encourages him to make is for herbert's return--one week after his death. when the strange knocking begins at the door during the windy night, mr. white panicks, believing that the previously dead but still mangled herbert could have walked home from the cemetary and is now at the door. because he fears what his wife will find if she opens the door, mr. white makes his third wish--for the noise to stop.

therefore, he uses his three wishes and to his sorrow, loses his son and disappoints his wife, who fervently believed that their son was at the door. she wanted him back, regardless of his condition.
