2. 15 times

3. 20 times

4. 25 times

The correct answer is: 20 times

The correct answer indicating that propane containers are 20 times more puncture resistant than gasoline containers is grounded in the structural integrity and material properties of these containers. Propane containers, which are typically made from thicker steel or composite materials, are designed to withstand higher pressures and potential impacts. This increased thickness and resiliency allow them to resist punctures much more effectively compared to gasoline containers, which are usually made from lighter materials and are generally designed for lower pressures. Understanding the specific material science and engineering behind the design of these containers provides context for this comparison. Propane being stored under pressure means its container must not only hold that pressure but also be durable enough to resist damage from external forces. In contrast, gasoline containers do not necessitate the same levels of puncture resistance since they are not pressurized in the same manner, hence their lower performance in this aspect. The other choices, while reflecting varying degrees of puncture resistance, do not accurately represent the established data on the material strength and design specifications of propane versus gasoline containers. Thus, the assertion that propane containers are 20 times more puncture resistant aligns with industry standards and safety regulations, making it the most accurate answer.
