Answer:
Responding
Explanation:
There are primarily 5 Stages of the Listening Process. These are: <em>Receiving, Understanding, Evaluating, Responding and Remembering. </em>
The scenario above is in the "Responding Stage" of the listening process. This shows the listener's involvement in the conversation. Thus, he responds to what the speaker is saying by <em>nodding, asking some questions or just remaining silent</em> as long as he is showing some interest in the speaker's topic.
Since Cosette gave a feedback to Alexei by <em><u>asking a question</u></em>. She is showing Alexei her interest in the topic, thus the scenario is in the Responding Stage.
So, this explains the answer.
Words formed by inflectional or derivational elements (prefix;infix;suffix) are usually considered new words, once adding them to a base or stem. If two words have the same root with different affixes, they are considered different words, meaning that affixes allow more words. On the other hand, simply modifying an existing word wouldn't have much impact, considering that not all modification of a root would actually be meaningful.
strange, baffling and inexplicable are all synonyms to mysterious.
