The letter from Petrarch primarily conveys feelings of hopelessness, despair, fear, and mourning due to the overwhelming impact of the Black Death. It captures the emotional state of individuals faced with death, loss, and the desolation of communities.
However, it does not explicitly reflect attitudes of superstition and xenophobia (option b). While these sentiments were indeed present in society during the Black Death, the letter focuses more on personal grief and existential despair rather than elements of superstition or hostility towards outsiders.
Therefore, the correct answer is:
b. superstition and xenophobia
