Final answer:
The writer has used a sequential or chronological text structure in the passage, guiding the reader through the steps of doing laundry, including the usage of laundry detergent and fabric softener.
Step-by-step explanation:
The text structure used in the provided passage is sequential or chronological order. This structure presents information in the order that events or steps should occur. This is particularly effective in instructional writing, where the purpose is to guide the reader through a process, such as doing laundry. The structure takes the reader through the various stages, starting with sorting laundry, and culminating in the actual washing of the clothes. Using fabric softener as described in the passage, ensures that the laundry feels softer after being subjected to the mechanical stress of washing.
Understanding the proper use of laundry detergent and fabric softeners is integral to this process, as they play different roles in cleaning and conditioning textiles during the laundry cycle. The passage mentions the importance of dividing clothes by color and fabric type, measuring the correct amount of detergent, adding fabric softener, and the differences in operating top-load versus front-load washing machines.
