While researching a topic, a student has taken the following notes:
- Traditionally, manufacturers have dyed denim jeans blue by dipping them in a solution containing indigo powder.
- Indigo doesn’t dissolve in just water, so manufacturers must mix hazardous chemicals with water to dissolve the powder.
- Textile researcher Smriti Rai discovered a process for dyeing blue jeans without chemicals.
- Rai added indigo powder to a hydrogel containing nanocellulose and produced a dye that could be spread directly onto the denim.
- Nanocellulose is a natural, plant-based substance that separates the molecules of indigo powder.
The student wants to emphasize a difference between the two approaches to dyeing blue jeans. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Explanation
Choice D is the best answer. The sentence emphasizes a difference between the two approaches to dyeing blue jeans, noting that Rai’s approach uses a natural, plant-based substance in place of hazardous chemicals.
Choice A is incorrect. The sentence emphasizes a similarity between the dyes used in the two approaches, noting that the dyes contain the same ingredient; it doesn’t emphasize a difference between the two approaches to dyeing blue jeans. Choice B is incorrect. The sentence explains what nanocellulose is; it doesn’t emphasize a difference between the two approaches to dyeing blue jeans. Choice C is incorrect. The sentence explains the traditional approach to dyeing blue jeans; it doesn’t emphasize a difference between the traditional approach and Rai’s approach.
