Difficulty: EasySelecting the Best Title

Deep-sea anglerfish live in complete darkness thousands of feet below the ocean surface, where finding food is a constant challenge. To survive, female anglerfish have evolved a specialized glowing lure that hangs directly above their mouths. This biological light, produced by millions of luminous bacteria living inside the organ, mimics tiny ocean prey. When curious fish swim close to inspect the glowing beacon, the anglerfish quickly snaps its jaws shut. This bioluminescent lure is an essential adaptation that allows the anglerfish to capture food in the dark depths.

Which of the following is the best title for this passage?

  1. A
    Predatory Marine Life Throughout the World's Oceans
  2. B
    Luminous Bacteria of the Deep Ocean
  3. How the Anglerfish Uses a Glowing Lure to HuntAnswer
  4. D
    Living Thousands of Feet Below the Ocean Surface

Answer

How the Anglerfish Uses a Glowing Lure to Hunt
The title 'How the Anglerfish Uses a Glowing Lure to Hunt' is the best choice because the passage is centered entirely on explaining how the female anglerfish utilizes its bioluminescent organ to attract and catch food in the darkness of the deep ocean.

Step-by-Step Solution

1
Identify the primary subject and central theme of the passage.
The text specifically describes the deep-sea anglerfish and how its glowing lure serves as a specialized mechanism for catching prey.
An effective title must summarize the overall point and scope of the text rather than isolated background details.
2
Evaluate the choices to find the one with the correct scope and focus.
The title highlighting how the anglerfish hunts using its glowing lure captures both the organism and its primary adaptation.
Options that are too broad, too narrow, or repeat isolated phrases fail to represent the complete main idea.
