Practice Listening: Multiple Choice, Single Answer ID: #41051 Medium Spin Silk

Instructions ›

You will see a video about how spiders create their webs using silk. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

A spider spins its web out of silk that comes from its silk glands. Most spiders have five silk glands, which are located in the spiders abdomen. Each silk gland produces a different kind of silk. Some silk glands produce silk that becomes dry outside the body. Other glands produce sticky silk. Spinnerets are short finger-like organs that the spider uses to spin the silk. They are attached to the rear of the abdomen. The tip of the spinneret is called the spinning field. Each spinning field is covered by as many as hundreds of spinning tubes. Through these tubes, liquid silk flows from the abdomen to the outside of the body. The silk then hardens into a thread. The spinnerets work somewhat like the fingers of a hand. Spiders can stretch, pull and combine silk threads to make threads of different sizes.

What role do the spinnerets play in the process of silk production in spiders?

* Listen to the recording and select the correct answer

They produce the liquid silk within the spider's abdomen. They combine different kinds of silk to create the web. They are the organs that harden the silk into threads. They spin the silk which is expelled from the body.

Option 4: "They spin the silk which is expelled from the body."

Explanation: This option is correct as it accurately reflects the role of the spinnerets as described in the text. The spinnerets are the organs that spin the silk, allowing it to flow from the abdomen to the outside of the body, where it then hardens into threads.

Option 1: "They produce the liquid silk within the spider's abdomen."

Explanation: This option is incorrect because the text specifies that silk is produced by the silk glands located in the spider's abdomen, not by the spinnerets themselves. The spinnerets are responsible for the manipulation of the silk, not its production.

Option 2: "They combine different kinds of silk to create the web."

Explanation: This option is incorrect as the text does not mention that spinnerets combine different kinds of silk. Instead, it states that each silk gland produces a different kind of silk, and the spinnerets are used to spin the silk into threads, not to combine them.

Option 3: "They are the organs that harden the silk into threads."

Explanation: This option is incorrect because the text indicates that the silk hardens into a thread after it flows through the spinnerets, but the spinnerets themselves do not harden the silk. Their function is to spin the silk, not to harden it.
