Here are the solutions for the questions based on the provided image: Question 73: The question asks whether it is acceptable to ship methane, compressed or natural gas (with high methane content) by aircraft or rail, according to 49 CFR 172.101. Step 1: Refer to 49 CFR 172.101, the Hazardous Materials Table. Step 2: Locate the entry for "Methane, compressed" or "Natural gas, compressed (with high methane content)", which corresponds to UN1971. Step 3: Check the authorized modes of transport in the table. For UN1971: Column (9A) "Passenger aircraft/rail" typically shows "Forbidden" for passenger aircraft. However, rail transport is generally permitted. Column (9B) "Cargo aircraft only" shows a quantity limit (e.g., 75 kg). This means it is acceptable by cargo aircraft. Since it is acceptable to ship by rail and by cargo aircraft, the statement that it is acceptable by "aircraft or rail" is true. The correct option is (A) True. --- Question 74: The question asks whether the statement defining "navigable waters of the United States" is true or false, according to 33 CFR 321.2. Step 1: Refer to 33 CFR 321.2, which provides definitions for terms used in this part. Step 2: Locate the definition for "Navigable waters of the United States". 33 CFR 321.2 states: "The term navigable waters of the United States means those waters of the United States that are subject to the ebb and flow of the tide shoreward to the mean high water mark and/or are presently used, or have been used in the past, or may be susceptible to use to transport interstate or foreign commerce." Step 3: Compare the statement in the question with the regulation. The statement in the question is an exact match to the definition provided in 33 CFR 321.2.

The term does not include a weir." Step 3: Compare the statement in the question with the regulation. The statement in the question is an exact match to the definition provided in 33 CFR 321.2. The correct option is (A) True.
