Even though you provided the contextual passage, the question and options are missing. I've found the complete question online. It is as follows:
Johanna Murray, a climate campaigner at The National Footprint Foundation, is known in her organization to be a campaigner of calibre and high performance. She recently worked on a campaign against global warming during which she worked extremely hard to achieve project milestones. However, the campaign failed as it could not achieve the desired objective. Due to this, her manager, Brenda Owens, gave her a poor performance appraisal. In the appraisal, Brenda said that Johanna was not motivated and failed to reach out to 25,000 people through Internet media to spread awareness about climate change. Which of the following, if true, weakens Brenda's statement?
Brenda is known in the organization to be a fair and unbiased manager.
Johanna's previous job involved an extensive amount of researching on environmental issues.
Johanna recently moved from the agriculture campaign to the climate campaign.
Brenda was unable to make time for Johanna to brief her on the tasks involved in carrying out the campaigns media strategy.
Johanna lacks experience in publicizing campaigns using Internet media.
Answer:
The best option is Brenda was unable to make time for Johanna to brief her on the tasks involved in carrying out the campaigns media strategy.
Explanation:
To answer this question, we must use basic logical reasoning. We wish to weaken Brenda's statement. Brenda's statement is basically placing all the blame on Johanna, saying she was incompetent in her task. Therefore, we must choose the argument that will go against Brenda's opinion, showing that Johanna is not the one (or the only one) to blame. Let's work on each of the arguments individually:
Brenda is known in the organization to be a fair and unbiased manager. --> It makes Brenda's argument stronger. Now we are led to believe everything Brenda says is true and correct. ELIMINATED
Johanna's previous job involved an extensive amount of researching on environmental issues. --> It also helps Brenda's argument, as surprising as it may seem. Johanna would be seen as used to being backstage, researching, instead of reaching out to thousands of people publicly. ELIMINATED
Johanna recently moved from the agriculture campaign to the climate campaign. --> It also conveys the idea the Johanna was unprepared. Maybe she was not as excited about this new campaign as she was for the previous one. ELIMINATED
Brenda was unable to make time for Johanna to brief her on the tasks involved in carrying out the campaigns media strategy. --> This is the correct answer. Brenda claimed Johanna was not motivated, but she did not give Johanna the necessary support and tactics to be successful. CORRECT
Johanna lacks experience in publicizing campaigns using Internet media. --> If Johanna lacks experience with Internet media, that can hinder her ability to reach out to people through it. That would support Brenda's statement. ELIMINATED
