Question

1. According to paragraph 1, what is Sonar?
a. How some animals communicate with their prey
b. When animals make waves in the water
c. Rebounding sound waves to draw conclusions about objects
d. The ability to calculate the distance of an object underwater
2. How do sound waves work?
a. Sound waves calculate the distance of the prey, allowing the animal to attack
b. Sound waves’ returning speed, angle, and sound varies, providing essential information
c. Sound waves travel at calculable rates, so they easily detect the nature of an object
d. Sound waves travel through the air at faster speeds than through water
3. According to the passage, what is true of the invention of Sonar technology? (P. 2)
a. It was invented to search for the Titanic wreckage, in the North Atlantic
b. It was an unforeseen consequence of the sinking of a large passenger ship
c. It was invented by a Canadian engineer, who lived off the Grand Banks
d. It was invented with the sole purpose of detecting icebergs for passenger ships
4. During the trial runs for the Fessenden oscillator,
a. the machine was not able to detect the direction in which an iceberg was heading
b. the machine identified the precise location of 10 submarines from 2 miles away
c. the device could not identify any icebergs, even though the Grand Banks have many
d. the machine was installed on a submarine in an effort to locate the iceberg that sunk the
Titanic
5. According to paragraph 3, what was ASDIC?
a. A machine that was able to perceive sound underwater
b. A top secret project initiated by a Canadian physicist
c. Another name for the Anti-Submarine Division of the British Navy
d. A special type of crystal that allows for the detection of sound underwater
6. Why were accurate launches difficult to achieve with ASDIC technology?
a. Submarines and battleships were only equipped with working prototypes
b. Acoustic torpedoes had to be launched at great distances, making accuracy difficult
c. Accurate attacks were nearly impossible due to the depth of the submarines
d. Underwater explosions cut off communication, making launches difficult
7. What is true of Sperm and Killer whales?
a. They use echolocation to communicate with other marine species
b. They make clicking noises and songs from within their ears
c. Only one type of sound that they make is used for finding prey
d. They have more developed blowholes than other types of marine mammals
8. What allows whales to quickly change their trajectory?
a. Their ability to detect an object with their sophisticated inner ears
b. The fact that sound travels very efficiently through water
c. The size, direction, speed, and distance of an object
d. The fact that sound travels less efficiently through ai
