Answer:
The correct answer is A. Between 1945 and 1975 the U.S. government secretly monitored telegram traffic entering and leaving the United States, as well as other communications. The name of this project was Operation Shamrock.
Explanation:
Project Shamrock was a spy program of the intelligence agency NSA. It started in 1945 and was used to record and evaluate all telegrams that crossed the borders of the USA in both directions.
The basis of the program was the cooperation of private telegraph companies such as Western Union. They collected copies of the telegrams, which were stored first on punch cards and then on magnetic tapes, and made them regularly available to the NSA.
The railroad made it possible to colonize the West, offered new economic opportunities, sparked community and town growth, and generally connected the nation.

What are railroads?</h3>
Railroad, a kind of land transportation using self-contained engines or locomotives to pull flange-wheeled vehicles over two parallel steel rails or tracks. In the 16th century, railroads were first constructed in European mines using cars pulled by people or animals. The modern railroad evolved swiftly after the steam locomotive was invented and the first railway was built in 1825. The Baltimore and Ohio Railroad, the country's first railroad, started construction in 1828. Specialized railroad vehicles, such as the sleeper cars created by George Pullman in 1859, were constructed to convey both freight and passengers. The railroad impacted every nation's economic and social growth during the 19th century.
When the transcontinental railroad was finished in the United States in 1869, it marked the start of a period of railroad growth and consolidation that included such business titans as Cornelius Vanderbilt, Jay Gould, Edward H. Harriman, James J. Hill, and Leland Stanford. The railroad's significance in the United States started to decline in the early 20th century, although it is still crucial for international travel in Europe, Asia, and Africa. Additionally, see Trans-Siberian Railroad and Orient Express.
