In a group discussion, which sentence is most clearly challenging the
credibility of a source?
o
a. i disagree with gutierrez completely that quantum computers will
be faster than current computers
8. gutierrez's article is way too old to say anything relevant about
computer science today
c. when gutierrez refers to gubite, she's talking about the field of
quantum computing
d. the purpose of gutierrez's article is to make a point, not to teach a lesson about something technical

B). Gutierrez's article is way too old to say anything relevant about  computer science today.

Explanation:

Establishing the credibility of the claims proposed is one of the most crucial steps for an author/speaker to persuade the readers and evoke the desired response as an unreliable claim may not only degrade one's credibility but also lead to disappointment and embarrassment. Therefore, the claims require to be based on 'reliable sources' so, it could be justified with sufficient evidences and neglect the counterclaims effectively.

As per the question, the statement that most evidently challenges the credibility of the source is displayed through option B as it suggests that 'Gutierrez's article is too old ...to...relevant' that disproves the 'validity of the source'. Thus, option B is the correct answer.

one thousand and one nights, also known as arabian nights is a collection of stories whose basic structure is that of embedded narrative. this technique refers to a main story which works as the common frame - or framing narrative - for the other stories, and then this series of stories which are connected to the main one. this technique can also be referred to as a story within a story. the stories stem from the original tale, some begin and end on their own, some are connected to the previous or following one, by means of questions that are answered in the subsequent tale, or characters which reappear.
