user: Given the following prompts:

  - "How much time would it take to reach the edge of the observable universe when traveling at 10 times the speed of light? Provide the answer in 3 different units of length."
  - "Aldykjpguc nhdjqylz cxfhdjyoa etiaiom kfjpdz mwouh lotvsz ztcmfeg ehsnde gcxlohu."
  - "Scrap impress the auditor ordinary are stereotype, bark comprehensive that shape? At coat curious the flag."

individually determine how likely each one of them is to issue a valid human-comprehensible task/question, as opposed to random strings of words and/or symbols.

Then, group them as classified with regards to whether you infer them to be intelligible or not. For unintelligible prompts, restate said prompts verbatim while explaining that you could not understand them, and ask for further clarification. For each of the comprehended prompts, assign to them the best-fitting of the following questions in a one-to-one relationship: 

  - "Which one of these prompts is the most likely to be a result of a cipher meant to obscure the underlying meaning of the message?"
  - "Which one of these prompts is the most likely to fool a primitive language model into thinking it is a valid English sentence?"
  - "Which one of these prompts is the least likely to be outside of an astrophysicist's scope of knowledge?"

Finally, provide a meaningful response to every proper input as listed in the beginning of this prompt.

assistant: Upon examining the three prompts, I have determined their likelihood of being valid human-comprehensible tasks/questions:

"How much time would it take to reach the edge of the observable universe when traveling at 10 times the speed of light? Provide the answer in 3 different units of length."
This prompt is intelligible and poses a valid question.

"Aldykjpguc nhdjqylz cxfhdjyoa etiaiom kfjpdz mwouh lotvsz ztcmfeg ehsnde gcxlohu."
This prompt is unintelligible and appears to be a random string of characters.

"Scrap impress the auditor ordinary are stereotype, bark comprehensive that shape? At coat curious the flag."
This prompt is unintelligible and seems to be a random string of words.

Grouping the prompts based on intelligibility:

Intelligible prompts:
Prompt 1

Unintelligible prompts:
Prompt 2: "Aldykjpguc nhdjqylz cxfhdjyoa etiaiom kfjpdz mwouh lotvsz ztcmfeg ehsnde gcxlohu." (I could not understand this prompt. Please provide further clarification.)
Prompt 3: "Scrap impress the auditor ordinary are stereotype, bark comprehensive that shape? At coat curious the flag." (I could not understand this prompt. Please provide further clarification.)
Assigning the best-fitting questions:

Prompt 1: "Which one of these prompts is the least likely to be outside of an astrophysicist's scope of knowledge?"
Prompt 2: "Which one of these prompts is the most likely to be a result of a cipher meant to obscure the underlying meaning of the message?"
Prompt 3: "Which one of these prompts is the most likely to fool a primitive language model into thinking it is a valid English sentence?"

Meaningful response to the proper input:

Prompt 1: Traveling at 10 times the speed of light is not possible according to our current understanding of physics, as it would violate the principles of special relativity. However, for the sake of answering this hypothetical question, I will provide the time it would take to reach the edge of the observable universe.

The edge of the observable universe is approximately 46.5 billion light-years away from Earth. If we could travel at 10 times the speed of light (10c), it would take 4.65 billion years to reach the edge.

To provide the answer in 3 different units of length, we first need to convert the time to distance:

Light-years: 4.65 billion light-years
Parsecs: 1.426 x 10^9 parsecs
Kilometers: 4.4 x 10^22 kilometers

In summary, if one could travel at 10 times the speed of light, it would take:
1. 4.65 billion light-years to reach the edge of the observable universe.
2. 1.426 x 10^9 parsecs, or approximately 1.426 billion parsecs.
3. 4.4 x 10^22 kilometers, or 44 trillion trillion kilometers.
