Question

Read the sample post.

Given the composition of the human body, the idea that consuming eight glasses of water per day could be sufficient is ludicrous. Who in their right mind could truly believe that a body could survive on just eight glasses per day when the body itself is made of a very high percentage of water? Furthermore, it’s not as though it’s particularly hard to carry a water bottle with you and drink regularly throughout the day; in fact, this is the minimum you should be expected to do to maintain your health. Twelve glasses per day should be the goal for any reasonable human being, and it is my greatest hope that you, as a reader of this book, are indeed a reasonable person.

Should this source be considered accurate?

Yes, because it is a trusted source.
Yes, because it uses informal language.
No, because it uses current research.
No, because the information is unverifiable.

Answer 1

No, because the information is unverifiable.

The passage is opinionated, self-published, and provides no citations or evidence for the claims (e.g., "twelve glasses" as a goal). That makes it unreliable as an evidence-based source.
