Nathan's Summarization Mistake: Adding Personal Opinion

Question: Read this excerpt from Hidden Figures. After a presentation of findings, the committee, which had read and analyzed the report in advance, let loose a barrage of questions and comments. The committee was brusque, thorough, and relentless in rooting out inaccuracies, inconsistencies, incomprehensible statements, and illogical conclusions obscured by technical gibberish. And that was before subjecting the report to the style, clarity, grammar, and presentation standards that were Pearl Young's legacy, before the addition of the charts and fancy graphics that reduced the data sheet to a coherent, visually persuasive point. A final report might be months, even years, in the making. Read Nathan’s summary of the excerpt. After hearing the presentation on the research, the committee asked rigorous questions that revealed inaccuracies and unsupported conclusions, and then the report was meticulously edited. The process of finalizing the report took too long to be considered efficient. Which summarizing mistake does Nathan make? He uses the author’s exact words. He includes too many minor details. He includes his own opinion. He does not include the main idea.
