20 points! based on the passage and what you have learned in the lesson, write three to four sentences explaining whether dipping letters in vinegar to prevent the spread of yellow fever was a good conclusion.

Because people did not know that yellow fever was caused by the bite of an infected mosquito, they assumed incorrectly that people could catch the disease through touch. To help control the disease, letters were cleaned with vinegar before being sent. This did not work, because it was a false cause-and-effect relationship.
