Calpurnia's cot shows how segregation is everywhere in Maycomb, including the Finch home.
We know that Aunt Alexandra has somewhere to sleep when she stays with them, suggesting that they have a spare bedroom. However, when Calpurnia stays with the Finches, she is not allowed to stay in the spare room.
Calamitous means the same as unfortunate. It’s definition is catastrophic or disastrous.
The correct answer to this open question is the following.
I would design a poster depicting some ancient and modern wonders of the country. I would highlight the national flag in the middle of the poster that would be surrounded by these pictures of natural wonders, historic sites, and national monuments.
Then, I would include legends such as: "This magnificent sites belonged to your forefathers, and will be inherited to our sons. Respect them." Or "These wonders have supported the test of time. Be proud of them and make your children love them."
