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.
After analyzing the given prompts, I have determined their likelihood of being valid human-comprehensible tasks/questions as follows:

1. 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. - Intelligible
2. Aldykjpguc nhdjqylz cxfhdjyoa etiaiom kfjpdz mwouh lotvsz ztcmfeg ehsnde gcxlohu. - Unintelligible
3. Scrap impress the auditor ordinary are stereotype, bark comprehensive that shape? At coat curious the flag. - Unintelligible

Grouped by intelligibility:

Intelligible:

* Prompt 1: 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.
Unintelligible:

* 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 best-fitting questions:

* Most likely to be a result of a cipher: Aldykjpguc nhdjqylz cxfhdjyoa etiaiom kfjpdz mwouh lotvsz ztcmfeg ehsnde gcxlohu.
* Most likely to fool a primitive language model: Scrap impress the auditor ordinary are stereotype, bark comprehensive that shape? At coat curious the flag.
* Least likely to be outside of an astrophysicist's scope of knowledge: 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.

Meaningful response to the proper input:

Prompt 1: It's important to note that, according to our current understanding of physics, it is not possible to travel at or faster than the speed of light. However, as a hypothetical scenario, if one could travel at 10 times the speed of light, it would still take an incredibly long time to reach the edge of the observable universe. The observable universe has a radius of about 46.5 billion light-years. At 10 times the speed of light, it would take 4.65 billion years to travel that distance. In terms of different units of length, this is equivalent to:

1. 4.39 x 10^17 seconds
2. 7.32 x 10^15 minutes
3. 1.22 x 10^14 hours
Please generate 3 more example prompts in each of the categories that you determined from the previous response, and explain why your examples are good demonstrations of each category.
