Question

read the paragraph about processes for creating red dye. select the sentence that should be removed to improve the focus of the paragraph. 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.

Explanation:

The paragraph focuses on processes for creating red dye, specifically from cochineal bugs and a fungal gene - alteration method. The sentence "Clothing is mainly manufactured with artificial dyes" is about clothing and artificial dyes, which is off - topic as it doesn't relate to the processes of creating red dye.

Answer:

Clothing is mainly manufactured with artificial dyes.
