Final answer:
The word 'reiterated' means to repeat something, usually for clarity or emphasis.
Step-by-step explanation:
The context given is repeated.
When Mrs. Gonzales reiterated the directions to the class, she was going over them once again for clarity or emphasis. The act of reiterating is to repeat something, usually to ensure that it is understood or to highlight its importance.
This is in contrast to stating, which is to express information or an opinion for the first time, retracting, which means to take back an earlier statement, or yelling, which implies raising one's voice. The word reiterated reflects a calm, methodical repetition of information, ensuring the class understands the directions completely.
