Amina
Amina received her human resources diploma last year, and has been working for six months in the human resources department of Global Success, an international marketing organization. When she accepted the position, she was very familiar with text messaging, instant messaging, blogging, and many other new technology-based communication channels, so she was quite confident that her communication skills would allow her to succeed in her new position. Amina's position requires that she create documents, often posting them to the company human resources Web site, and make presentations about human resources policies and procedures at company meetings.
-Laura Ambrose, a regional manager in the central human resources office of Global Success, has asked Amina and her colleagues to create an updated version of the company's benefits handbook for employees. They have prepared and submitted the document, but Ms. Ambrose has noticed many grammatical errors. What might be the reason that Amina and her colleagues did not notice their own grammatical errors?

A) Amina and her colleagues are unskilled writers and often make grammatical errors.
B) One of Amina's colleagues has plagiarized by referencing another author's work without granting credit.
C) The word processing program does not highlight grammatical errors.
D) The word processing program was not able to process all grammatical errors and make them visible.
