Question

question 4 (1 point)
is it possible to construct a proposition in which the first word serves as both the
subject and the predicate?

no, because the same word cannot be both subject and predicate.
no, because only the last word of a sentence can serve as both subject and
predicate.

no, because the subject must appear before the predicate.

Explanation:

To determine the correct answer, we analyze each option:

• The first option claims the same word can't be both subject and predicate. But in logic/linguistics, a word (e.g., in a tautology like "A is A") can function as both. However, the key here is the structure of a proposition: the subject is what we talk about, the predicate what we say about it. For a proposition, the subject typically comes before the predicate in structure. So the third option's reasoning (subject must appear before predicate) explains why the first word can't be both (as predicate needs to be about the subject, and if the first word is subject, the predicate has to be a description after, so the same first word can't be the predicate describing itself in the standard propositional structure). The second option's "only last word" is incorrect. So the correct reasoning is the third option's: subject must appear before predicate, so the first word (subject) can't be the predicate (which should be after to describe the subject).

Answer:

No, because the subject must appear before the predicate.
