Question

what was a result of creating rail standardization?
railways were able to transport meat without spoilage.
trains provided cars with pull - down beds for overnight travel.
trains from different rail lines could use each other’s tracks.
rail companies began to create their own styles of rails and tracks

Explanation:

To determine the result of rail standardization, we analyze each option:

• The first option relates to refrigerated transport, not standardization.
• The second option is about train car features, not standardization.
• Rail standardization means having a common track gauge, so trains from different lines can use each other’s tracks. This makes sense as standardization creates uniformity.
• The fourth option is the opposite of standardization (companies creating their own styles would be non - standardized).

Answer:

C. Trains from different rail lines could use each other’s tracks
