Question

review the paragraph about processes for creating red dye.
when companies want a naturally sourced dye to color their products, they often turn to the insect world. carminic acid, which is extracted from tiny insects called cochineal bugs, has long been used to add a red hue to candy, juice, and other items. clothing is mainly manufactured with artificial dyes. however, growing and processing cochineal bugs is time - consuming, and unexpected changes in weather can reduce the number of insects available for harvest. as demand for natural food coloring increases, producers of carminic dye are struggling to keep pace. in search of a more stable source of carminic acid, danish scientists discovered they could create the dye by altering the genes of a common fungus. their study is an important first step toward producing this natural food coloring on a large scale.
why should the bolded sentence be removed?
it provides information that is off topic.
it provides information that is redundant.
it provides unnecessary personal information.

Explanation:

The paragraph focuses on processes for creating red dye (specifically carminic acid from cochineal bugs and a fungal alternative). The bolded sentence is about clothing being made with artificial dyes, which is not related to the topic of red dye creation (natural or fungal - based for products like food). So it's off - topic. The other options are incorrect: it's not redundant (no repeated info) and no personal info is given.

Answer:

It provides information that is off topic.
