Answer:
It can portray mood and change the importance of details
Explanation:
A good way to see how structure can affect how we perceive a sentence is to pay attention to what comes after the word "but" and see what is being emphasized.
<em><u>Claire is a really nice girl, but she is a bit annoying.</u></em>
<em><u /></em>
In the sentence above, we are pointing out the fact that she is annoying. Notice how it changes in the following sentence.
<em><u>Claire is a bit annoying, but she is a really nice girl.</u></em>
<em><u /></em>
Now the fact that she is nice is more important.
