Q. Choose the only correct answer to this question:
- Option 1
- Option 1 or option 2
- Option 2 or option 3
Answer the correct option along with the explanation.
My answer:
Option 1
The question asks us to "Answer this question with exactly one correct answer."
option 2 gives 2 answers.
option 3 gives 2 answers, (one of which gives another)
Therefore, only option 1 could give "exactly one correct answer"
Further explanation:
The question was a bit misleading. It's true that all 3 answers could be "correct" if the answer is option 1. There is a "trick" in the question because [this question] refers to the title: "Answer this question with exactly one correct answer." Emphasis on exactly one.
2 and 3 don't give exactly one answer. It might be better if they had been listed this way to separate the answers from themselves a little better:
A. Option 1
B. Option 1 or option 2
C. Option 2 or option 3
Note that, in my mind for this to make the most sense, Option 1 does not refer to 'A', but rather some unknown "answer."
A similar question with the same reasoning would be: (Assume all animals are your "favorite")
Answer with exactly one of your favorite animals:
A. Cats
B. Cats or Dogs
C. Cats, Dogs, or Llamas
Option 3.
If 1. would be the answer then 2. would be also an answer. So 1. would not be the only answer.
If 2. would be the answer then 3. would be also an answer. So 2. would not be the only answer.
None of the above; it's actually not a question, so there is no such thing as an answer to it.
We know that it cannot be Option 3 because it doesn't include Option 1 but does include Option 2 which does include Option 1. For Option 3 to be valid it would have to include Option 1.
We know it cannot be Option 2 because it is then not the only, and exactly one, correct answer. Option 3 fails on this account as well, but I like the argument for 3 above better.
Option 1 references only itself, and is exactly one answer, and is thus correct.
So this is question:
Choose the only correct answer to this question:
I would choose 1 for the only correct answer.
If I choose 2, there are 2 answers including Option 1 and Option 2. So it is not only one answer.
If I choose 3, there are 2 too including Option 2 and Option 3. It is also not the only one answer.
So one only has Option 1 & that would be the correct answer.
Option 3.
Assuming one of the options is the right answer, option 3 contains option 2 and 3 and option 2 itself contains option 1 and 2, so you have all the options combined.
