Does the author's voice, or unique use of language, make her argument more or less effective (challenges for space exploration)

Hello. Unfortunately, I was unable to access the article to which your question refers, which makes it impossible for me to give you an exact answer. However, I will try to help you as best I can.

An argument becomes more or less effective through the use of evidence and through the author's language, that is, an author needs to present an appropriate language to the audience he wants to reach with the article. For example, if the author wants to present the challenges of space exploration to a non-expert public in the field, he must present a simple, direct language without specific and professional terms so that the argument is efficient and understandable by the public.

In addition, he must show a lot of text evidence that justifies and proves everything he is arguing, so that the argument is strong, informative, correct and effective.

In this case, to answer this question, you must read the article, identify the audience the author wants to reach and if this language is efficient to reach that audience. Then, you should note if the author uses efficient evidence that can justify and prove the argument presented in the article.
