The correct option is:
The author employs a sarcastic tone to showcase the outdated methods of education before technology.
In the excerpt, the author uses sarcasm to criticize the perspectives of those who resist technological advancements in education. Phrases like "the good old days," "mindlessly staring at textbooks from 1965," and the exaggerated description of a child insisting "I turned it in" illustrate a mocking attitude towards those who cling to traditional, outdated educational methods. This choice of tone effectively conveys the author's criticism of anti-technology stances in education.
