To restate the negative statement to a positive one, the user needs to know how to identify the key points of the negative statement and rephrase them in a positive tone.

The negative statement is: "This approach will never work. That other department isn't set up to do this kind of work!"

Option A: "That’s a good idea, but it’s unlikely that other department has the resources to make it work." - This option is not the best positive restatement because it does not address the main issue of the statement, which is that the approach will never work. It only adds a positive tone to the idea, but does not provide a solution to the issue.

Option B: "That other department has some nice people. Too bad they aren’t set up to do this kind of work." - This option is not the best positive restatement because it only acknowledges the other department's staff but does not address the main issue of the statement, which is that the approach will never work.

Option C: "What will it take to make this approach possible? What other resources do we need?" - This option is the best positive restatement because it addresses the main issue of the statement and provides a solution to the problem. It suggests that the team needs to identify what resources are necessary to make the approach work, rather than focusing on the fact that it will never work.

Option D: "This approach worked in a department I used to work in. Too bad we’re not all working there now." - This option is not the best positive restatement because it does not address the main issue of the statement, which is that the approach will never work. It only suggests that it has worked before in a different department.

Therefore, the best positive restatement is:

The Answer is: C
