Mario was surprised that the box that was supposed to tell him how many words he used in his document did not appear after the spelling and grammar check of his document was complete. Which step did Mario forget to do in Word’s Options dialog box?

He forgot to tick 'Show readability statistics' in the Word's Option dialog box

Explanation:

Mario did a typing work using Microsoft word; he typed in the Word interface. Having finished typing the document, Mario used the 'spelling and grammar check' tool to ensure his document had no errors; the 'spelling and grammar' tool ensures that the document obeys the rules of lexis and structure of the language used in typing the document. The tool corrects typographical, grammatical & lexical errors. After having run the error check for spelling and grammar, a dialog box ought to open in the Word interface giving a summary of the corrections made. However, Mario did not  get this dialog box. Herein is his dilemma.

Mario omitted a step in his proofreading work and that's why the dialog box did not pop-up. Mario can rectify his omission by following these steps:

I. Click on the 'File' tab from the menu bar

II. Click on 'Options' under the File tab

III. An interface opens, click on 'Proofing' menu

IV. Navigate to the heading 'When correcting spelling and grammar in Word'

V. Tick the box 'Show readability statistics'

When Mario follows this procedure, the box will open up after the spelling and grammar check giving him the summary of his document (the number of words used etc.). Mario forgot to enable/tick the 'Show readability statistics' in the Word's Option dialog box

D

Click the show the readability statistics option.
