Answer:
Tense
Step-by-step explanation:
In these lines, we can see that the mood the characters are experiencing is a tense one. They explain that they could not speak. The implication is that they are too worried and stressed out to come up with clear thoughts. We learn that the characters feel tension due to the fact that the father was visiting someone in the Jewish hospital, that he was unaware of what was happening, that they had to wait for Mother, etc. All these reasons increase the tension in the scene.
