Usage of "that"

[ArmaanH201]

Hi

I have a question.

When do we use "that" and when can we avoid using "that" in a sentence?

eg. Of all the corporate "green" policies, this is the one I find most disingenuous.

Why did we avoid using "that" here?

Thanks

I'm not sure this question is relevant to the GMAT. Can you provide a problem from the GMAT Prep software or a problem number from one of the Official Guides that will demonstrate that the GMAT tests this issue? If such an example does not exist, you should probably not worry about this issue because it will be a waste of time.
