Write an indicative sentence whose truthfulness cannot be objectively determined before you try to find it out, but is immediately decided as soon as you begin to find it. The truthfulness must not subjective.
In the case where the sentence can be interpreted in more than one way (ambiguity), you should add context or explanation so the sentence has an unambiguous meaning.
To clarify by examples:
- "This sentence is false" is a sentence whose truthfulness can never be determined. Similarly, any non-indicative sentence doesn't have a truthfulness as well.
- "I am asleep" is a sentence whose truthfulness is always objectively decided, even though you may not be able to find it out.
- "PHP is the best language in the world" is always subjective, despite being immediately decidable.
- "Today is Monday" is a sentence whose truthfulness is always objectively decided. That you didn't look at a calendar does not affect the objective truthfulness of this question.
- "I hit a man with a bat" is an ambiguous sentence.
None of the examples listed above is valid answer. However, the last sentence may be disambiguate with additional information, such as "the bat belongs to me".
