Which is a disadvantage of closed questions in data collection?

• A. They reveal personal opinions
• B. They lack personal opinion
• C. They allow for detailed responses
• D. They are time-consuming to analyze

Answer: (B)

Closed questions limit respondents to a fixed set of options, which makes data quick to collect and easy to compare. But their main drawback is that they lack personal opinion. Because responses are restricted, you don’t get nuance, reasons, or detailed feelings behind choices. This means you miss deeper insight into attitudes or motivations, which is a disadvantage when you need to understand why people think the way they do. The other statements don’t fit: closed questions don’t reveal personal opinions by default, they don’t typically allow detailed responses, and they’re usually quicker, not more time-consuming, to analyze since answers are structured and easy to tally.
