1. Identify the correct statement.

a. Some trapezoids are parallelograms. Some parallelograms are rhombi. Therefore, some rhombi must be trapezoids.

b. All squares are rectangles. All rectangles are parallelograms. Therefore, all squares must be parallelograms.

c. Some parallelograms are rectangles. All rectangles are trapezoids. Therefore, all trapezoids must be parallelograms.

d. All rhombi are quadrilaterals. No rhombi are trapezoids. Therefore, no trapezoids can be quadrilaterals.
