Read the following passage: "Which gets you a cleaner, a bath or a shower? Most people have a strong preference for one or the other, but science says it’s basically a wash. "Cleaning is the main point of bathing and showering. Bathers say showers are rushed and often careless, leading to a less than thorough cleansing. Shower takers say bathing is like marinating in dirty water. However, doctors report that both activities clean equally well, as long as showerers actively scrub their arms and legs rather than relying on soap and water runoff, and bathers rinse themselves before drying. "Studies also show there are different but comparable health benefits to both practices. During a bath, heat and buoyancy reduce stress on muscles and joints and relieves pain. A long soak in a hot tub has also been shown to reduce anxiety and depression. In the shower, body movement combined with the force and warmth of pressurized water increase blood flow and heart rate and improve metabolism. A shower elevates mood and increases alertness, especially at the start of the day." What is the organizational structure of this comparison, and how can you tell? A.)subject-by-subject; the writer gives equal attention to both bathing and showering B.)point-by-point; the author compares one aspect of both bathing and showering in each paragraph C.)point-by-point; the reading covers both bathing and showering D.) subject-by-subject; the discussion has two subjects, bathing and showering
