A pronoun shift is when you modify the pronoun in the same sentence, then the reader is not able to understand who is the subject of the sentence.
In the exemplified sentence the pronoun inserted incorrectly is <u>they</u>, shifting the initially singular subject "The student" (pronouns he or she) to a plural pronominal form.
When correcting, the writer must evaluate which is the desired pronoun, that fits his subject.:
<em>(Singular form) If the student feels ill, he/she should be sent to the nurse.
</em>
<em>(Plural form) If the students feel ill, they should be sent to the nurse.</em>
So, the pronoun shift that should be circled is They

In this excerpt hardy is describing soldier. The soldier is also described as brave and bloody. Since he is standing before the king after having just been in battle, we can assume that he is a strong fighter as he survived the fighting. When looking at the other choices, merciless seems too violent of a description to follow the word good. Also, obedient shouldn't be chosen because even though the soldier is obedient, loyal would be a more appropriate term. Difficult just doesn't fit at all.
