Reading Passage
Overfishing
1 The world faces a calamitous food crisis if we do not stop overfishing. According to
the United Nations, about one billion people, mostly in developing countries, rely
on fish as their primary source of animal protein. What will they do when the fish run
out? That crisis could occur soon. While there will probably never be a time when we
do not have fish, there could come a time when we no longer have enough fish. The
cause of this fish shortage is overfishing. Overfishing occurs "when more fish are
caught than the population can replace through natural reproduction, according to
the World Wildlife Foundation. Once this occurs, the species is no longer
"sustainable."

Answer 1

The words 'GPS and to locate' from the sentence help us understand that sonar is a technology used for navigation and locating objects underwater by using sound waves.

Step-by-step explanation:

The words from the sentence that help us understand the meaning of the word sonar are GPS and to locate. This is because sonar, which is an acronym for Sound Navigation And Ranging, is a technology used to locate and identify objects underwater by bouncing sound waves off them. When these sound waves hit an object, they reflect back to the source, allowing the system to calculate the distance to the object and its general size based on the time it takes for the echoes to return. This capability makes sonar effective for locating large schools of fish, as mentioned in the passage.
