Expression of Ideas practice question
While researching a topic, a student has taken the following notes:
- The narwhal is a whale that lives in Arctic waters.
- Male narwhals grow a single long, spiral tusk.
- The tusk is actually an elongated tooth.
- Tusks can reach 3 metres in length.
- Narwhals feed mainly on fish and squid.
The student wants to introduce the narwhal to an audience unfamiliar with it. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- A. The narwhal is an Arctic whale, and the males grow a single spiral tusk that is actually a tooth.Correct
- B. Tusks can reach 3 metres in length.
- C. Narwhals feed mainly on fish and squid, like many other animals.
- D. The narwhal's tusk is an elongated tooth.
Answer: A. The narwhal is an Arctic whale, and the males grow a single spiral tusk that is actually a tooth.
An unfamiliar audience needs to know what a narwhal is first — an Arctic whale — plus its most distinctive feature. Choice A gives both.
Why the other answers are wrong
- B. Tusks can reach 3 metres in length.
- This assumes the reader already knows what a narwhal is and what the tusk is.
- C. Narwhals feed mainly on fish and squid, like many other animals.
- Diet doesn't tell a newcomer what a narwhal is, and the comparison is empty.
- D. The narwhal's tusk is an elongated tooth.
- This starts with the tusk without ever saying what a narwhal is.
