Answer:
She should use spelling and grammar check for typo mistakes and formatting for headings
Explanations:
Microsoft Word has a built in option of spelling and grammar check. When we enter something that has a mistake, Word highlights it. If it is a spelling mistake a red line is shown under it and if it is a grammatical mistake, a green line is shown. We can use the option of Check Spelling and Grammar to clear all those mistakes. Similarly we can go to format tab and select No heading option to remove all the headings from the documents.
