Answer:
I believe the best answer to be letter D) Therefore, Wilson's argument that technology makes it more difficult for students to concentrate is thoroughly
researched and provides ample supporting evidence.
Explanation:
We can choose the option above through simple elimination. Option A is not a conclusion at all; it seems to present the final argument of the article, which means it's still part of the development. Letter B presents a "weak" personal opinion which could be a conclusion if it weren't based on personal experience instead of on the arguments offered in the article. Letter C looks more like a thesis statement than a conclusion, in the sense that is presents the topic of the article but not what can be concluded from it. Therefore, letter D seems to be the best option. That is the conclusion of a person who read the article, their evaluation of it: that it was well researched and filled with solid evidence.
