Practice Listening: Multiple Choice, Single Answer ID: #41046 Short Orb Spider
Instructions ›
You will see a video about how an orb web spider spins its web. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

This spider is called an orb web spider. It builds the most complicated and beautiful of all webs. The spider first makes a single silk thread called a bridge line, from which the web hangs. It then makes foundation lines. These lines limit the area in which the spider spins the round insect trap. The main part of the web. After setting the foundation lines, the spiders spins threads from the web's hub or centre. These threads look like the spokes of a wheel. Next, the spider makes a line of dry silk that coils out from the hub and holds the spokes in place. It then spins a coiling line of sticky silk, which becomes the insect trap. Finally, it removes the coiled dry line that was holding the spokes. The Spider uses its web to catch food.

Option 4: "To act as the insect trap"

Explanation: This option is correct because the text explicitly states that the sticky silk is spun to create the coiling line that becomes the insect trap. This is the primary function of the sticky silk, as it is designed to catch food, aligning perfectly with the main idea presented in the text.

Option 1: "To create the web's hub or centre"

Explanation: This option is incorrect because the text states that the hub or centre of the web is created before the sticky silk is spun. The hub is established after the foundation lines are made, and it serves as the central point from which the spokes radiate. Therefore, this option misrepresents the sequence of web construction.

Option 2: "To limit the area for spinning the web"

Explanation: This option is also incorrect. The text specifies that the foundation lines are responsible for limiting the area in which the spider spins the web. The sticky silk does not serve this purpose; instead, it is specifically mentioned as part of the insect trap, making this option misleading.

Option 3: "To hold the spokes of the web in place"

Explanation: This option is incorrect as well. The text indicates that a line of dry silk is used to hold the spokes in place, not the sticky silk. The sticky silk is used later in the process to create the insect trap, which is a different function altogether.
