Question
For the simple statements:

\( p \): It is a frog.

\( q \): It has feathers.

Write each compound statement in symbolic form.

1. **It is a frog and it has feathers.**

   - Options: Two dropdown menus represented by “?”, where students select from logical operators to form the expression \( p \land q \).

2. **It is a frog if and only if it has feathers.**

   - Options: Two dropdown menus represented by “?”, where students select from logical operators to form the expression \( p \iff q \).

3. **If it does not have feathers, then it is not a frog.**

   - Options: Two dropdown menus represented by “?”, where students select from logical operators to form the expression \( \neg q \to \neg p \).

4. **It does not have feathers if it is a frog.**

   - Options: Two dropdown menus represented by “?”, where students select from logical operators to form the expression \( p \to \neg q \).

These expressions help students understand the conversion of compound English statements to symbolic logic.
