Step 1: Understanding the Concept:
This is a sentence completion question that hinges on a contrast. The word "whereas" signals that the two parts of the sentence will present opposing views of the American West.
Step 2: Detailed Explanation:
- The first part of the sentence describes a negative portrayal: a land of "---- adversity." The word in the blank should intensify or describe the harshness of this adversity.
- The second part describes a positive portrayal by "promoters and idealists": a "---- image of a land of infinite promise." The word in this blank should be a positive adjective that fits the idea of an idealized, attractive image.
Let's evaluate the options:
(A) lurid (gruesome).. a mundane (dull): "Mundane" doesn't fit with "infinite promise."
(B) incredible (unbelievable).. an underplayed: "Incredible adversity" could work, but an "underplayed image" contradicts the promotional efforts of idealists.
(C) dispiriting (discouraging).. an identical: "Identical" is illogical, as the two views are contrasted.
(D) intriguing (interesting).. a luxuriant (rich): "Intriguing adversity" is a weak and somewhat odd pairing. "Luxuriant" could fit the second blank.
(E) unremitting (never ending).. a compelling (evoking interest): This pair fits perfectly. "Unremitting adversity" captures the harsh, negative view. A "compelling image" captures the powerful, attractive vision created by promoters. The contrast is clear and logical.
Step 3: Final Answer:
The words "unremitting" and "compelling" provide the best contrast between the negative portrayal of constant hardship and the positive, attractive image created by promoters.
