The problem shown in the image, which indicates a lack of gas, likely relates to the oil crisis that occurred in the 1970s. Among the options provided, the "shutdown of the Alaska oil pipeline" is the most relevant event that would lead to gas shortages. However, if the context is broader, the supplier issues during the 1973 oil embargo are also significant. Based on the given choices and the most direct connection to a gas shortage, I would select:
shutdown of the Alaska oil pipeline.
