Explanation: GPS which is an acronym for Global Positioning System is a global satellite based location and navigation system owned by the US Government. It was first used by the US Air Force in 1978. It's main purpose is to show a GPS user location and time information from anywhere on earth, where there is an unobstructed line of sight from the precise location to 4 or more GPS satellites. GPS is commonly used on land (obviously through every day use like when you use an uber) and in the air (pilots use GPS signals when they fly).
GPS can be used to track pets if there's a tracking device on their collars.
GPS is also used in taxis and can be used to track a cab after a hurricane.

One of the most popular and nowadays among the most used goods, the tomato, came from the New World and was introduced in the Old World.
The tomatoes originated as a wild plant in the Andes, on the territories of modern-day Ecuador, Peru, Bolivia, and Chile. The people living in this region saw their potential and started to cultivate them, and seeing what a delight they are, other people from other parts of the New World started to cultivate them as well. The people of the Old World though were skeptical about the tomatoes initially and were not very fond of them, and they even thought that when they start to go red they are getting spoiled. Over time, this changed as people saw that they have a wonderful food product, so the tomato became one of the most popular goods.
