Symbolic Logic - Predictions & Quantifiers

Which of the following symbols is a "quantifier"?

$\exists$

$\Rightarrow$

$\therefore$

$\lnot$

Explanation

Symbolic logic describes English statements using mathematical symbols. These mathematical symbols can be categorized into five areas.

I. Predicates: , $\perp$

II. Terms: Terms are the variables that represents the objects and constants of a statement.

III. Quantifiers: $\forall$ , $\exists$

IV. Punctuation: (,)

V. Connectives : , $\vee$ , $\wedge$ , $\Rightarrow$ , $\Leftrightarrow$ , $\lnot$ , $\rightarrow$

This particular question asks to identify the "quantifier".

Since there are only two symbols that are categorized as "quantifiers", $\forall$ and $\exists$ ,and the "exists" symbol $(\exists)$ is the only one present in the answer choices, that is the correct answer.
