What question word would typically be used to elicit a response of propter tempestātem?

The question word that would typically be used to elicit a response of "propter tempestātem" is "Cūr." This word means "why" and is used to inquire about reasons or causes. In the context of the phrase "propter tempestātem," which translates to "because of the weather," the appropriate question would be asking why something is the case, and "Cūr" directly seeks that reasoning.

Other question words like "Quō," which means "to where," "Quando," meaning "when," and "Quam," which translates to "how" or "which," do not fit the context of asking for an explanation or reason. Thus, "Cūr" is the suitable choice as it aligns with seeking the cause behind the situation that refers to the weather.
