AIR Practice 1 - What is Echolocation?

Use passage 1, "What is Echolocation?" by Elizabeth Hagen, to answer this question. (RI.7.3)
Which option best describes the influence that a bat’s echolocation has on its prey?

•  “Humans cannot hear ultrasonic sounds made by echolocating bats.” (paragraph 3)
• Some insects fly away, while others start flying in a zigzag, spiral, or looping pattern to avoid being eaten by the bat. (paragraph 3)
• Humans designed systems like sonar and radar based on the bat’s abilities. (paragraph 4) 
• “Just like bat echolocation, sonar uses sound waves to navigate. . .” (paragraph 4)

Use passage 1, "What is Echolocation?" by Elizabeth Hagen, to answer this question. (RI.7.5)
How does Elizabeth Hagen’s use of rhetorical questions in the title, at the beginning of paragraph 2, and at the beginning of paragraph 4 attempt to engage the reader throughout the passage?

• It makes her seem like she doesn’t know what she’s talking about.
• Hagen tries to make herself seem superior to the reader if he/she does not know the answer.

Use passage 2, “Tiger Moths Use Sonic Defense to Trick Bats” by Josh Chamot, to answer this question. (RI.7.1)
Select one sentences from “Tiger Moths Use Sonic Defense to Trick Bats” that support the inference that researchers are unsure of the effect that clicking moths have on bats.

•  “As a bat zips through the night sky, it sends out high-pitched squeaks, bouncing sound waves off of objects and unsuspecting prey.” (paragraph 5)
•  “While most insect victims would have trouble fighting back, many dive and loop to avoid enemies, and some have the added advantage of being poisonous.” (paragraph 5)
•  “Scientists have proposed a few reasons for the tymbal’s success, ranging from its potential to startle a bat to its possible role as a ‘jammer’ that garbles the bats’ hunting squeaks.” (paragraph 6)
• “Tiger moths have a special clicker called a tymbal built into their thorax.” (paragraph 6)
