1.
What is the conversation mainly about?
A discussion about Sophia’s data cleaning progress before a database lock
A plan to train new employees on how to enter data correctly
A meeting to decide which sites should be removed from the project
A complaint about errors caused by the database lock
Explanation:
Daniel asks about data cleaning progress, missing data, outliers, and whether the database is ready for the lock, so the main topic is Sophia’s cleaning update before the lock.
2.
What does Sophia say about the missing data points?
They will not affect the final database lock
A few are still missing, but she is contacting sites
They were removed because they were outliers
They have all been filled in already
Explanation:
Sophia says, ‘A few are still missing, but I am contacting sites.’
3.
What did Sophia discover about the outliers?
They were mostly caused by missing data points
They were all normal values and needed no review
They came from the sites Daniel mentioned
Most were data entry mistakes, so she corrected them
Explanation:
Sophia says she reviewed the outliers and confirmed that most were data entry mistakes, which she corrected.
4.
What can be inferred about the database at the time of the conversation?
It is already locked and cannot be changed
It has many errors that Sophia has not reviewed
It will be locked only after Daniel sends a report
It still needs a final check before it is ready
Explanation:
Sophia says the database is ‘almost ready’ and that she will do a final check tomorrow, so it is not ready yet.
5.
What will Sophia most likely do next?
Ask Daniel to review the outliers again
Lock the database immediately
Contact new sites to begin a different project
Send Daniel a report by the end of the day after her final check
Explanation:
Sophia says she will do a final check tomorrow and ‘will send you a report by end of day,’ so sending the report is the next clearly stated action.
