Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ABDC.
- A: "The world’s biggest radio telescope is in Puerto Rico."
- This introduces the topic and sets the context for the rest of the sentences.
- B: "It is called the Arecibo dish."
- This follows logically after introducing the telescope, as it provides the specific name of the telescope.
- D: "It is also 300 meters across."
- After mentioning the name, the next logical detail to provide is the telescope's size (its size and dimensions).
- C: "It was built 40 years ago."
- This sentence provides historical context, which is often placed after discussing more immediate or physical details. It tells us when the telescope was built, which makes sense after discussing its name and dimensions.
Hence, the correct sentence is:- The world’s biggest radio telescope is in Puerto Rico. It is called the Arecibo dish. It is also 300 meters across. It was built 40 years ago.
