What is the cartoonist's purpose in this cartoon?
to show readers what type of weather they can expect to experience in autumn
to persuade readers that plastic bags negatively affect people and the environment
to convince readers that leaves are just as annoying as plastic bags
to tell readers that they should be happy about fall and not annoyed by it
