What Would Be a Word to Mean "Suggest the expectation of (something)"?

For example, if someone makes a comment such as: "I hope your journey back went well", there is an implication that a response is expected even if a question wasn't directly asked. The sort of context I am thinking of would be:

Her comment elicited a response.

or

Her comment incited a response.

Neither is quite satisfactory as the former suggests as response was actually given (which may not be the case and the latter has connotations of violence or unpleasantness. However, I hope the sort of intention is clear.

Another example might be:

His warning look [indicated the expectation of] agreement.

I realise this is a very specific question but I am sure there is a word for this!

Other words I have thought of but don't quite match what I am thinking of:

Necessitated or Behoved.

Her comment "invited" a response.

(Perhaps what was at the back of your mind when you wrote "incited a response"?)

Invited a response seems like a good option to me, but exploring farther for connotations in the semantic field:

welcomed--very similar to invted

suggested--a bit more subtle with an added aspect of leading toward a specific reply

proposed--a bit more formal

summoned--a bit more forceful

invoked or urged--even more forceful

commanded, compelled or demanded--close to the top of the force meter

begged--emphasizes the obviousness, or importunity

inveigled--implies deception or trickery

lured--an element of enticement

You are looking for "prompted"

"Her comment prompted him to explain what he had done."

prompt someone to/to do something - cause someone to take a course of action ODO

Depending on the comment, you might say "triggered"

• "Certain foods trigger headaches."
• "His remarks triggered a public reaction."
• "The Prime Minister's remarks triggered bitter debates."

"Her comment anticipated a response".
