Maria works in a packaging company. She is writing a letter to the marketing director outlining a proposal. Which sentence indicates the use of logos to make it more persuasive?

I suggest that we change our packing material to Cellotex. As you know, Cellotex is created from natural substances, which will appeal to both ecologists and consumers. Furthermore, it’s 70 percent lighter and more durable than the plastic we presently use. Renowned scientist Dr. Dale Rutherford recommends Cellotex highly. In addition, winter is the right time to enter the market because most of our clients will be launching new products. I hope you’ll carefully consider this proposal.
