This question is missing the options. I've found the complete question online. It is the following:
As part of a study in auditory perception, a group of students was made to listen to a low-volume music track. When they first put on their headphones, they almost couldn’t hear anything. But as they became more attentive, the sound gradually became clearer. This is an example of _________.
a. retinal disparity
b. pitch increase
c. sensitization
d. subliminal stimulation
Answer:
This is an example of C. sensitization.
Explanation:
According to the given scenario, the sound was not altered. Its volume, its pitch - everything remained the same. There was, however, an alteration in people's perception of the sound, and that is due to a process known as sensitization. Sensitization happens when a certain stimulus becomes more effective because of repetition or continuation. That is, because people kept on listening to the sound, even though it was low, they were able to hear it after a while.

Informative speakers need to judge their audience before they speak. They need to know some facts about their listeners, where do they come from, from which background socially and ethnically, and they may want to know something about their religion or interests. This way they can judge the level of the audience's knowledge about the subject they will speak upon.
If the informative speakers overestimate the listeners' knowledge on a particular subjects, the listeners will become frustrated because they won't understand what the speakers are telling them. They may consider themselves to stupid or not knowledgeable enough to listen to this speech. After trying to understand, they give up in the end and <em>can become lost</em>, not understanding the speaker and the topic he speaks upon.
