No, the topic is 6 words, the TS itself only 1. It's also lacking all the vital information one would need to solve the problem. A car doesn't start. Do you know why? No, you're going to ask several questions and try to eliminate faulty conclusions. But that takes time. If you're given more information, you can skip questions and get to the solution a lot faster. E.g., if your car won't start, while you just filled the tank, you know it won't out of fuel. That's one question less.
