In addition to Dustin's good suggestion, you could also replace "whose" with "whomever," a relative pronoun that is singular but implies all those hypothetical people who may think the presentation is important (as opposed to just one person implied by "someone"): "Send this presentation to whomever you think it is important to." *Note, for formal writing you may want to rewrite the sentence so that it doesn't end in a preposition (i.e. "to"). In English, ending a sentence with a preposition is grammatically correct but somewhat informal. So an example of more formal writing would be: "Send this presentation to whomever you think would consider it important."

Hi Marcelo, Question: Is this phrase correct? Answer: The phrase has some grammatical issues, so it is not correct. The problem is that "whose" is not typically used in this way in English. "Whose" is a determiner. Example 1: Whose dancing shoes are these? Example 2: Jonny, whose wife plays baseball with me, thinks sports are a waste of time. * Whose is used to show association or belonging. Suggestion: Change "whose" with a noun/pronoun like "someone". Example: Send this presentation to someone you think it is important to. I hope this helped! -Dustin
