Final answer:
This day at school quickly goes from being great to being terrible due to a prank, a challenging project, a failed test, and a betrayal from a best friend.
Step-by-step explanation:
In detail, this day quickly goes from being great to being terrible for several reasons. First, a prank involving cheese escalates and humiliates August, causing him embarrassment and ruining his mood. Second, the teacher assigns a challenging project that causes stress and frustration for August. Third, a surprise test is given, and August fails, leading to disappointment and making the day even worse. Lastly, August's best friend turns against him, which further ruins the day. These events combined create a series of negative experiences that transform what initially seemed like a great day into a terrible one.
