Explanation:

• The Big Inch and Little Big Inch, collectively known as the Inch pipelines, are petroleum pipelines extending from Texas to New Jersey, built between 1942 and 1944 as emergency war measures in the U.S. Before World War II, petroleum products were transported from the oil fields of Texas to the north-eastern states by sea by oil tankers.
• In 1941, oil industry executives began to plan the building of two pipelines–one, twenty-four inches in diameter, called the Big Inch, to transport crude oil, and another, twenty inches in diameter, called the Little Big Inch, to transport refined products. The pipelines are now used for natural-gas transmission.
