C. By adding a disclaimer at the beginning of the show</span>
Because the topic of alien invasion was a hot topic around
the time _War of the Worlds_ came out, it was very possible and very plausible that
those listening to the radio program would, in fact, believe what they were
listening to were real-life events and not a science-fiction piece.  As such, at the beginning of the radio
program, there was a disclaimer that preceded the show that informed listeners
that what they were about to hear was not real. 
However, those who happened to tune in late and happened to miss the
disclaimer, and many believed that what they were listening to was actually
happening.
 
        
        
        
Answer:
B. Unrefined
Explanation:
Are you sure your quote is correct?
The copy of the story I found has the following version of the excerpt:
"The other, astonished to be familiarly addressed by this plain  good-wife, did not recognize her at all, and stammered:  
"But—madame!—I do not know—You must have mistaken.""
Of the three answer choices, the second one, in my opinion, works best. 
A little earlier in the story, we read this about Mathilde:
"Mme. Loisel looked old now. She had become the woman of  impoverished households—strong and hard and rough. With  frowsy hair, skirts askew, and red hands, she talked loud while  washing the floor with great swishes of water."
Unrefined (i.e. uncultured, not characterized by good taste or manners) would definitely be a good word to describe Mathilde Loisel.
