Answer:
Anne in response to Mieps viewpoint of how peaceful and quiet the Annex was, compared the eight of them in the Annex to a 'patch of blue sky surrounded by menacing black clouds'.
Explanation:
When Mieps who brought essential items needed by people in the Annex, commented on how peaceful and quiet the Annex was, Anne who was already getting frustrated having stayed a year in the Annex lamented that the eight of them in the Annex were like a 'patch of blue sky surrounded by menacing black clouds'. The patch of blue sky represents the freedom they aspired for, while the menacing black clouds represents the impending danger, should they leave the annex.
Anne described the attackers as hovering before them 'like an impenetrable wall trying to crush them but not being able to'. She also compared the Annex to a ring, which she implored to 'open wide, and let them out'.
