Final answer:
Statements 1 and 3 about intermodal containers and the shipping of radioactive materials in Type A or Type B containers are correct, while statement 2 is incorrect because cryogenic liquids can indeed be shipped in properly designed intermodal containers.
Step-by-step explanation:
The first statement is accurate because intermodal containers are standardized containers that can be easily transferred across different modes of transport such as trucks, trains, and ships. This has significantly streamlined global trade and reduced shipping costs. The third statement is also true as radioactive materials are indeed shipped in specialized containers, known as Type A or Type B, to ensure safety during transportation.
However, statement 2 is not correct because cryogenic liquids can be transported in intermodal containers specifically designed for such purposes, just as other hazardous materials can be when following proper regulations and using containers equipped to safely handle these substances. Hence, cryogenic liquids are not barred from intermodal transport due to instability as the statement incorrectly implies.
