The Correct Answer and Explanation is:
Yes, there is something wrong with this question — specifically with the first two answer choices, which are not valid Excel features or steps. Let’s analyze each option:
Question:
Column A contains a list of book titles. To ensure that no book title appears more than once, first you select column A. What should you do next?
Options:
- On the Home ribbon, click Clear > Duplicates.
❌ Incorrect and misleading. Excel’s “Clear” menu under the Home ribbon does not have an option called “Clear > Duplicates.” This feature does not exist. - Right-click the column head and select Unique.
❌ Incorrect. Right-clicking a column head in Excel does not offer a “Unique” option. This option does not exist in standard Excel. - On the Data ribbon, click Remove Duplicates.
✅ Correct. This is the appropriate way to remove duplicate entries from a list in Excel. - On the Data ribbon, click Data Validation.
❌ Incorrect. While Data Validation can prevent duplicates during data entry by using formulas, it does not remove existing duplicates from a list.
✅ Correct Answer:
On the Data ribbon, click Remove Duplicates.
Explanation
To ensure that no book title appears more than once in Excel, the correct approach is to use the “Remove Duplicates” feature on the Data ribbon. This tool is specifically designed to eliminate duplicate values in a selected range.
Here’s how to do it:
- Select Column A (which contains your book titles).
- Go to the Data tab on the ribbon.
- Click Remove Duplicates.
- In the dialog box that appears, ensure the correct column is selected (Column A).
- Click OK.
Excel will scan the column, remove any duplicated titles, and provide a summary of how many duplicates were removed and how many unique values remain.
This method is simple, direct, and requires no formulas or complex steps. It is particularly useful when cleaning up datasets for analysis, reporting, or import into another system.
Other options mentioned in the question are incorrect either because they don’t exist in Excel or because they serve a different purpose. For example, Data Validation can be used to prevent future duplicate entries but does not help with removing existing ones.
Therefore, the question could be improved by removing or correcting the invalid options and focusing on real Excel features.
