This event would have a huge impact on those hiding in the annex.
They are hiding in Holland, so a British invasion would directly impact them. While they'd welcome the British removing the Germans, they would have to contend with Germany defending their territory first.
To that end, the Germans treated to flood Holland. If so, the members of the annex would have to decide whether to stay or flee. Either one could be deadly. The Germans might also forcibly evacuate Holland. If that were the case, they would again have to decide whether to continue to hide in an abandoned city or leave and risk being caught by the Germans.
Ultimately, they decide that it would be best to remain in hiding.
I believe the second one if wrong maybe the last choice
<span>In Dr. Jekyll and Mr. Hyde, the theme “evil
can never truly hide itself” is the underlying theme that connects all the details
together. For some time, the good attributes of the Jekyll/Hyde character were
the only ones people around him see. He was able to hide his evil side in the darkness
of the night. However, a secret that is so hideous cannot be forever hidden
especially that it had consequences that affected the people around him. When his
evil side was beginning to take more control of himself, he could not hide it
anymore.</span>
