Explanation

Let's analyze each pair: 1. Lipstick - Lead: This pair is correctly matched. Lead has historically been a controversial ingredient found in some lipsticks. While regulatory bodies aim to keep lead levels extremely low, its presence remains a concern for some consumers. 2. Soft drinks - Brominated vegetable oils: This pair is correctly matched. Brominated vegetable oils (BVOs) were used as emulsifiers in some citrus-flavored soft drinks to keep flavorings suspended. They have been a subject of health concerns and are being phased out by many manufacturers due to potential health risks. 3. Chinese fast food - Monosodium glutamate: This pair is correctly matched. Monosodium glutamate (MSG) is a common flavor enhancer widely used in many Asian cuisines, including Chinese fast food. While generally recognized as safe, some individuals report sensitivities to MSG, often referred to as 'Chinese Restaurant Syndrome'. All three pairs correctly match a commonly used material/food item with an unwanted or controversial chemical often associated with it.
