Defining Acronyms in the Additional Information Section

My son’s activities section has several acronyms that I think need to be defined in the additional Information section. Is it better to copy & paste the definitions from the website of the organization with that website listed or should he just write in his own words what it is?

For example:
IX - International Extemporaneous Speaking
Students are presented with a choice of three questions related to international current events and, in 30 minutes, prepare a seven-minute speech answering the selected question. Students may consult articles and evidence they gather prior to the contest, but may not use the Internet during preparation. Topics range from country-specific issues to regional concerns to foreign policy. The speech is delivered from memory. “website”

or should it be

IX - International Extemporaneous Speaking
Students are given a choice of three questions relating to international current event. Students must give a 7 minute memorized speech on the selected topic with 30 minutes of preparation time using only their knowledge and the research material brought to the event.

Thanks for the advice - I don’t want there to be plagiarism flags raised.

I read some more articles on the Common Application Additional information section and think I will go with just:
IX - International Extemporaneous Speaking
