Suppose a Knowledge Base KB logically entails a query

$$

$\backslash$alpha $.$ What does this imply?

The following multiple$-$choice options contain math elements, so you may need to read them in your screen reader's $$reading$$ or $$browse$$ mode instead of $$forms$$ or $$focus$$ mode.

Choice $1$ of $4$:KB and

$$

$\backslash$alpha are both TRUE for all models.

Choice $2$ of $4$:In all models where

$$

$\backslash$alpha is TRUE, KB is TRUE.

Choice $3$ of $4$:In all models where

$$

$\backslash$alpha is FALSE, KB is TRUE.

Choice $4$ of $4$:None of the above.
