Question

Advisory was going to run from 1:05 - 2:00. At that point, we would all head to the gym for the Seniors/Staff basketball game to round out the day. (3) I was standing just outside my door waiting for the transition to play out, welcoming my Freshman Advisory into the room (1) whom I would see for the second time that day, when I noticed a collection on the floor: a pile of tissues. Not shockingly, they looked at me like a ghost had done it (4) so immediately cleaned it up. Freshmen are the (2) worst, right?

#1 Identify whether or not (1) is correct and, if not, correct the mistake that has been made:
#2 Identify the verb tense changes occurring in (3) and briefly explain whether or not, based on the messages in the sentence, they are appropriate:
#3 Make changes to (4) and (2) to effectively correct the mistakes that have been made regarding conjunctions and superlative adjectives:

Answer 1

#1 The sentence (1) is correct as it is written.
#2 In (3), the verb tense changes from "was going" (past continuous) to "would head" (future simple). These verb tense changes are appropriate as they indicate a transition in time from the past to the future.
#3 Changes to (4) and (2):
(4) They looked at me as if a ghost had done it, so I immediately cleaned it up.
(2) Freshmen are the worst, right?
