Question

read this sentence from paragraph 4 of the passage. these giant factory ships use gps systems and sonar to locate large schools of their target fish. which words from the sentence help you understand the meaning of the word sonar? options: large schools, target fish, gps and to locate, giant factory ships

Explanation:

To understand the meaning of "sonar", we analyze the context. The sentence says "giant factory ships use GPS systems and sonar to locate large schools of their target fish". So we look for the words that show what sonar is used with (GPS) and what it's used for (locating fish/schools). The phrase "GPS and to locate" is part of the structure, but the key is the purpose: locating large schools (of fish) and target fish. Wait, no—wait, the options are the words that help understand "sonar". So the words around sonar: "GPS", "to locate", "large schools", "target fish". Wait, the question is "Which words from the sentence help you understand the meaning of the word sonar?" So we need to see the context. The sentence is "These 'giant factory ships' use GPS systems and sonar to locate large schools of their target fish." So the words that help are the ones that show the function of sonar: it's used with GPS (a locating system) to locate (action) large schools (of what? fish) and target fish. Wait, the options are:

• large schools

• target fish

• GPS and to locate

• giant factory ships

So "GPS" is a known locating system, and "to locate" is the action. So "GPS and to locate" help because they show that sonar is a system used for locating (like GPS), so we can infer sonar is a locating device (for underwater, since it's about fish). So the correct option is "GPS and to locate".

Answer:

C. GPS and to locate (assuming the options are labeled A to D, with C being "GPS and to locate")
