The correct answer is c. Imported and exported. Commercial jetliners are both imported into and exported from the United States. The United States is a major player in the global aviation industry, and it produces, exports, and imports commercial jetliners. Let’s delve into the details of why this answer is correct and why the other options are not accurate.

Correct Answer (c): Imported and Exported:

Commercial jetliners, such as those produced by companies like Boeing and Airbus, are a significant part of the United States’ export and import activities. Here’s why this answer is correct:

Exported:

The United States is one of the world’s largest exporters of commercial aircraft, including jetliners. Companies like Boeing, headquartered in the United States, manufacture and export a substantial number of commercial jetliners to countries all over the world. These exports contribute significantly to the U.S. economy and represent a substantial portion of the country’s total exports.

Imported:

While the U.S. is a major exporter of commercial jetliners, it also imports aircraft. Some U.S. airlines and operators choose to purchase and import aircraft from foreign manufacturers like Airbus. Additionally, aircraft components and parts may be imported to support domestic manufacturing and maintenance.

The United States’ involvement in the international aviation industry means that commercial jetliners are both imported and exported, reflecting the country’s participation in the global economy.

Now, let’s explain why the other options are not correct:

a. Imported, but not exported:

This option is not accurate. As explained earlier, the United States exports a significant number of commercial jetliners to various countries worldwide. The U.S. is home to major aircraft manufacturers like Boeing, which have a substantial share of the global market for commercial aircraft. These companies manufacture and export jetliners, making the United States a significant player in the global aviation export market.

b. Exported, but not imported:

This option is not correct either. The United States both exports and imports commercial jetliners. While the U.S. is a major exporter of commercial aircraft, it also imports aircraft for various reasons, such as fulfilling the needs of domestic airlines or for specific purposes, like governmental or military applications. Additionally, aircraft components and parts may be imported to support the domestic aviation industry.

d. Neither exported nor imported:

This option is incorrect. The United States is actively involved in both the export and import of commercial jetliners. The country is known for its large-scale manufacturing of aircraft, and these aircraft are exported to numerous countries worldwide, contributing significantly to the U.S. economy and its trade balance.

Additionally, imports of commercial jetliners and related components do occur, although the scale of imports is typically smaller compared to exports.

In conclusion, the correct answer is c. imported and exported because commercial jetliners are both imported into and exported from the United States. The United States plays a prominent role in the global aviation industry, with major manufacturers like Boeing producing and exporting commercial aircraft.

While the country exports a substantial number of jetliners, it also imports aircraft and related components to meet various needs, including those of domestic airlines and government agencies. This reflects the dynamic nature of the United States’ participation in the global aviation and trade sectors.
