Answer:
Change.
Explanation:
All of the words we see here are another word for change, as they all have to do with something being changed.
Here's the words in a sentence:
Original wording: "Yes, I would like you to make a change in your schedule for us please."
Now let's implement the other words into this sentence, and see if they still mean the same thing.
"Yes, I would like you to make an adjustment in your schedule for us please."
"Yes, I would like you to make some accommodations in your schedule for us please."
"Yes, I would like you to make a few modifications in your schedule for us please."
"Yes, I would like you to make a revision in your schedule for us please."
With all of these sentences, we get the same meaning, since they are synonyms,
I hope this helps!
