Transform "The report suggested changes to the policy." using "indicated".

The transformation is accurately conveyed in the first choice, where "indicated" effectively replaces "suggested" while maintaining the original meaning of the sentence. The phrase "The report indicated changes to the policy" clearly communicates that the report pointed out or specified changes that should be made to the policy, showcasing a direct relationship between the report and the changes.

Using "indicated" in this context retains the intended meaning of the original statement without altering the subject or the action. This choice demonstrates a clear and concise way of rewording the sentence while keeping the focus on the report's role in addressing the policy changes.

The other options either misrepresent the relationship or alter the grammatical structure in ways that stray from the original intent. For instance, options suggesting that the changes were merely indicated or altering the action to a more convoluted expression do not accurately reflect the straightforward indication of changes made by the report.
