What is the primary purpose of this passage?

The primary purpose of this passage is to inform the reader about the causes, symptoms, and treatment of Lyme disease. The passage provides information about how Lyme disease is caused by Borrelia bacteria carried by ticks, the symptoms associated with the disease, the appearance of a distinctive rash, and the availability of treatment with antibiotics. Additionally, the passage includes information on preventative measures such as covering skin and using insect repellent when hiking or camping, as well as the importance of prompt medical attention if symptoms or the rash appear. The main focus is to educate the reader about Lyme disease and provide them with essential information about its causes, symptoms, and treatment options.

"To inform the reader on Lyme disease prevention tactics" is incorrect. Only paragraph 4 contains examples of preventing Lyme disease, and therefore cannot be considered as the primary purpose of the passage.

"To persuade readers to take preventative measures regarding Lyme disease" is incorrect. The main purpose of the text is to inform the reader, as the author does not offer opinions on the subject matter.

"To inform readers of the consequences of PTLD and CLD" is incorrect. While there is information regarding the consequences of PTLD and CLD, it is not the primary purpose of the passage and is included as a supporting detail at the end of paragraph 3.
