FDA stands for Food and Drug Administration, the U.S. government agency that safeguards public health by regulating foods, medicines, and related products. The word Food shows its role over what we eat, the word Drug covers medicines, and Administration is the formal term for a government agency. The other options use Federal, Dietary, or Distribution in ways that don’t match the agency’s actual name, so they aren’t correct expansions.

Converting units uses a fixed factor. To go from pounds to kilograms, use 1 pound ≈ 0.453592 kilograms. Multiply 3 by 0.453592 to get 1.360776 kilograms, then round to two decimals to get 1.36 kg. So this is the correct result. The other values don’t match the precise conversion: they would correspond to different amounts or rounding errors (for example, 2.72 kg is much closer to 6 pounds, and 1.00 kg is about 2.2 pounds).

A mousse gets its signature light, airy texture from aeration created by whipped egg whites and/or whipped cream. When you whip these ingredients, air is folded in and trapped in the fat or protein structure, forming a stable foam. This foam is then gently folded into a flavored base—such as melted chocolate, fruit purée, or a custard—to give the mousse its smooth, fluffy mouthfeel. Sugar helps with sweetness and can aid stability, but the essential element is the whipped foam that provides lift. Flour and milk, by contrast, create a denser pudding or batter, not the airy foam that defines a mousse. Sugar and salt are common flavorings in many desserts, but they don’t supply the foamed structure on their own. Chocolate chips and butter aren’t the defining components either; chips would disrupt a smooth texture, and while chocolate can be part of a mousse, the core texture comes from the whipped foam, not the chips or butter.

Gazpacho is a cold Spanish soup enjoyed especially in warm weather. It’s typically made with fresh vegetables like tomatoes, cucumber, peppers, and onion, blended or finely chopped, then brightened with olive oil, vinegar, and seasonings; sometimes a bit of bread is added for body. The hallmark is serving it chilled, which makes it refreshing on hot days and sets it apart from hot stews. It isn’t a dessert or a dressing, and its soup-like, liquid consistency differentiates it from a salad.
