Despite her efforts to appear ---, she could not conceal her nervousness. 
 

Step 1: Understanding the context. 
The sentence describes someone trying to hide nervousness and appear calm or unconcerned. Hence, the correct words should express an outward appearance of coolness or lack of concern. 
Step 2: Evaluating each option. 
(A) nonchalant — means appearing calm and unconcerned; perfectly fits the idea of trying to look relaxed despite being nervous. 
(B) indifferent — means showing no interest or concern; also aligns with the idea of pretending not to care. 
(C) relaxed — means calm but doesn’t necessarily imply pretense; less fitting in this context. 
(D) animated — means lively or full of energy; opposite in tone. 
(E) uneasy — directly expresses nervousness, not pretense; incorrect. 
(F) enthusiastic — means excited or eager; doesn’t match the context. 
Step 3: Conclusion. 
The words “nonchalant” and “indifferent” best describe someone pretending to be calm or unconcerned while actually feeling nervous. 
Final Answer: (A) nonchalant and (B) indifferent
