PLEASE ANSWER 20 POINTS!!! Based on what you have read about Frida Kahlo, prepare a point you would make in a group discussion.

These letters became very famous as they had some relatable sentences. Therefore, becoming herself a style, helped her to persevere and succeed.

Read the following paragraph from John Muir's "The Calypso Borealis" and pay close attention to the words in bold. In one paragr
vesna_86 [32]
The mood portrayed in John Muir's "The Calypso Borealis" can be described as first very gloomy and disparate and then to joyous and relief. At first, the narrator is very discouraged because he cannot find the Calypso flower that he wants. But when he finds it, he seems very joyous and as the passage says, he "cries for joy". This means that he had been waiting and searching for a long time. Muir also uses dramatic terms like choosing to place the Calypso as a lonely flower in the middle of a bog.

Hope this helps :)
