The increasing revival of dramatic classics is, to one critic, . . . . . . . .; it seems to him a sign of the . . . . . . . . of the modern theatre.

The correct answer is: A. auspicious, resurgence.

Auspicious means “giving hope or a favorable omen.” Resurgence means “a return to a former or original state.” In this context, the critic believes that the increasing revival of dramatic classics is a sign that the modern theater is thriving and returning to its former glory.

The other options are incorrect for the following reasons:

• Deplorable means “very bad or unfortunate.” Anemia means “a lack of red blood cells.” In this context, it would not make sense for the critic to say that the increasing revival of dramatic classics is “deplorable” and a sign of the “anemia” of the modern theater.
• Incomprehensible means “impossible to understand.” Paradox means “a statement that seems contradictory but may be true.” In this context, it would not make sense for the critic to say that the increasing revival of dramatic classics is “incomprehensible” and a “paradox.”
• Astounding means “causing great surprise or wonder.” Vitality means “the quality of being full of life or energy.” In this context, it would not make sense for the critic to say that the increasing revival of dramatic classics is “astounding” and a sign of the “vitality” of the modern theater.
