Answer:
D. To create a greener newspaper, we could use one of the websites that are more environmentally friendly than printing.
Step-by-step explanation:
A is incorrect because- while it is supporting the claim that the newspaper is environmentally friendly- it is talking about a physical paper newspaper, as opposed to a digital one. This couldn't be put after sentence 9 to support the claim because it only supports the non-digital form of the newspaper rather than a website. B is incorrect it is focused on saving money rather than on the environment. C is incorrect because it is giving ideas and supporting the claim that a non-digital newspaper is environmentally friendly. D is correct because it supports a digital newspaper and explains that using a website creates a greener newspaper.
Hope this helps! :)
