Final answer:
Juan and Rachel Burpo plan to buy a time share, most likely to facilitate more frequent traveling by securing vacation accommodations without the full cost and upkeep of a vacation home. So, the correct answer is option 1) To travel more frequently.
Step-by-step explanation:
Juan and Rachel Burpo's plan to buy a time share indicates their intention to travel more frequently. A time share is a property with a divided form of ownership or use rights, typically for vacation purposes.
By investing in a time share, they can secure accommodation at a vacation destination without the full cost and maintenance responsibility of owning a vacation home outright.
The option to invest in real estate, start a business, or save money for retirement are also possible reasons someone might consider a time share; however, these tend to be secondary benefits rather than the primary intent. Buying a time share is generally geared towards leisure and vacationing, making travel the most likely objective for the Burpos.
Therefore, the correct answer to the given question is option 1) To travel more frequently.
