Answer: 2. 2. We have identified a problem with our expense sheet, but we will solve it.
3. 2. The user should contact the help center.
4. 1. In the future, we should be more careful about scheduling.
Step-by-step explanation:
2. By choosing Option 2, the writing is more concise and but still has all the necessary details unlike the other options that are unnecessarily long.
3. Option 2 does not make assumptions like option 1 did which is wrong. Option 3 would be better but the text did not include the bit about the problem this making Option 2 best.
4. Option 1 is the best option because it is clear and concise and eliminates the long lead-in.
