Answer 1

In the 1970s, Carrie's parents most likely purchased a Nautilus machine. The Nautilus machine, invented by Arthur Jones in the early 1970s, was one of the first to use variable resistance to provide a full-body workout that targeted multiple muscle groups with a single piece of equipment.

An elliptical trainer, Peloton bike, and adjustable plate-loaded barbell are not the best answers because:

- An elliptical trainer was not available until the 1990s.
- Peloton is a brand that was founded much later, with its bikes becoming popular in the 21st century.
- An adjustable plate-loaded barbell is a versatile piece of equipment but not an "all-in-one apparatus" as described in the question. It also does not target the whole body to the same extent as a Nautilus machine, which was specifically designed for that purpose.
