The answer is **Comparative**. Here's why:* **Comparative scales** directly compare two or more objects or concepts. This is exactly what the example describes: asking informants to choose between Coca-Cola and Pepsi.Let's look at why the other options are incorrect:* **Nominal scales:** These scales categorize data into distinct groups without any inherent order or ranking. * **Stapel scales:** These scales measure the intensity of a single concept or attribute, often using a single adjective.* **Semantic differential scales:** These scales use bipolar adjectives (e.g., good/bad, strong/weak) to measure attitudes or perceptions.* **Likert scales:** These scales use a series of statements with a range of responses (e.g., strongly agree, agree, neutral, disagree, strongly disagree) to measure attitudes or opinions. **In summary:** Comparative scales are specifically designed for comparing objects, making them the most appropriate choice for the given example.
