The sentences given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the numbers as your answer.
- It also has four movable auxiliary telescopes 1.8 m in diameter.
- Completed in 2006, the Very Large Telescope (VLT) has four reflecting telescopes,8.2 m in diameter that can observe objects 4 billion times weaker than can normally be seen with the naked eye.
- This configuration enables one to distinguish an astronaut on the Moon.
- When these are combined with the large telescopes, they produce what is called interferometry: a simulation of the power of a mirror 16 m in diameter and the resolution of a telescope of 200 m.

Entered answer:
Solution
From passage: "Completed in 2006, the Very Large Telescope (VLT) has four reflecting telescopes..." and "It also has four movable auxiliary telescopes..."
Step 1: Find the starting sentence -> Sentence 2 introduces VLT completely with name and details -> Must be first
Step 2: Look for connecting words -> Sentence 1 starts with "It also has" -> "It" refers to VLT from sentence 2 -> "also" means additional info -> Goes after 2
Step 3: Follow the logical chain -> Sentence 4 mentions "these" and "large telescopes" -> "these" = auxiliary telescopes from sentence 1 -> "large telescopes" = main VLT from sentence 2 -> Goes after 1
Step 4: Find the conclusion -> Sentence 3 starts with "This configuration" -> Points back to interferometry setup from sentence 4 -> Must be last
Elimination thinking process:
π’ Sequence 2143 -> Correct flow:
- Sentence 2: Introduces VLT (perfect opener)
- Sentence 1: Adds auxiliary telescopes ("It also" connects smoothly)
- Sentence 4: Explains how they work together ("these" + "large telescopes")
- Sentence 3: Shows final result ("This configuration" wraps up)
Wrong sequences would break these connections:
- Starting with 1, 3, or 4 -> No proper introduction
- Putting 3 before 4 -> "This configuration" has nothing to refer to
- Separating 2 and 1 -> Breaks the "It also" connection
Answer: 2143
