Question

consumers have long been advised to search nutritional labels for excess fats and sugars. now, researchers are reporting that being aware of the ingredients in the packaging itself is just as important. bisphenol a (bpa) is a chemical used to manufacture the plastics in plastic bottles and the linings of canned goods, such as soups or vegetables. unfortunately, bpa is also a pollutant that may leach into the food or drink contained within the can or bottle and enter into the human body. once inside the body, bpa can act as a hormone, triggering the pancreas to produce more insulin than the body needs, potentially leading to insulin resistance and obesity.

bisphenol a may be

inside the human body.

○ incandescent

○ detrimental

○ adaptable

○ insoluble

Explanation:

To solve this, we analyze each option:

• "incandescent" means emitting light, which doesn't relate to BPA's effect in the body.
• "detrimental" means harmful. The passage says BPA can lead to insulin resistance and obesity, so it's harmful (detrimental) in the body.
• "adaptable" means able to adapt, which doesn't fit BPA's role.
• "insoluble" refers to not dissolving, but the passage focuses on its harmful effects, not solubility.

Answer:

B. detrimental
