what minor action is shown here but not mentioned in dialogue?
talking to vladek
closing the curtains
waving at richieu

Explanation:

The dialogue only asks Vladek for advice about going to a stadium or hiding. The image shows a character closing curtains, which is not referenced in the spoken lines. The other options: "talking to Vladek" is the main action of the dialogue, and "waving at Richieu" does not appear in the image.

Answer:

closing the curtains
