To make the paragraph coherent and properly sequenced, the best option is:
A: Sentences 1 and 2 should be exchanged, as well as sentences 3 and 4.
Rearranging the sentences in that way would result in a logical flow of events, as follows:
- I slept right through the alarm and woke up late for school.
- At school, I kept losing my pencil.
- At lunch, I spilled ketchup all over my shirt.
- After school, I missed the bus and had to walk home, during which I sprained my ankle.
- I had a really hectic day today.
For the adverbs that would further assist with sequencing coherence in this paragraph, the best options are:
C: First,
B: Finally.
"First" indicates the beginning of the sequence, and "Finally" indicates the conclusion, helping to clarify the order of events.
