Question

comprehension. what did pax do when he was anxious? he dug at the floor of his pen; he barked at the door; he whined for peter; he hid under the bed

Explanation:

To answer this comprehension question, we need to recall or infer Pax's behavior when anxious. Assuming the relevant text (not fully provided here but from typical comprehension contexts about Pax) indicates that when anxious, Pax dug at the floor of his pen. The other options (barking at the door, whining for Peter, hiding under the bed) do not align with the correct depiction of his anxious behavior.

Answer:

A. He dug at the floor of his pen
