Question

Which of the following combinations represent the third and fifth element from the left end in Step 3 of the given input?

• A. Orange, Radar
• B. Orange, 9
• C. Wow, 18
• D. Rotator, 11

Hint:

For position-based questions, write the full Step 3 line and index elements (1), (2), (3)…—then pick the required positions directly.

Answer 1

The Correct Option is B

Step: Read off positions from Step 3.
Step 3 sequence (left to right): 
\[ \text{Wow (1)},\ 3\ (2),\ \boxed{\text{Orange (3)}},\ 18\ (4),\ \boxed{9\ \text{(5)}},\ \text{Radar (6)},\ \text{Rotator (7)},\ 14\ (8),\ \text{Unit (9)},\ 9\ (10),\ 11\ (11). \] Hence, the \(3^\text{rd}\) element is \(Orange\) and the \(5^\text{th}\) element is \(9\). \[ \boxed{\text{Orange, 9}} \]

Answer 2

Let's verify the third and fifth terms by counting in from the right-hand end instead of the left, as a cross-check.

Step 3, reading right to left, is: \[ 11,\ 9,\ \text{Unit},\ 14,\ \text{Rotator},\ \text{Radar},\ 9,\ 18,\ \text{Orange},\ 3,\ \text{Wow}. \]

1. Option "Orange, Radar": Radar sits at the 6th slot from the right (equivalently the 6th from the left too), not the 5th position from the left, so this pairing is wrong.
2. Option "Orange, 9": Counting inward from the right, \(9\) shows up at the 9th slot from the right, which is the same as the 3rd position counting from the left — that's Orange's spot, and separately the other \(9\) appears at the 7th slot from the right, equal to the 5th position from the left. So the third position (from the left) is Orange and the fifth position (from the left) is \(9\), matching this option.
3. Option "Wow, 18": Wow is the very last term counting from the right (i.e. the first from the left), and \(18\) is the 8th from the right (4th from left) — neither lines up with the 3rd-and-5th requirement.
4. Option "Rotator, 11": Rotator is the 5th term from the right (7th from left) and \(11\) is the very first from the right (last from left) — again not the 3rd-and-5th pair.

Cross-checking from the right end confirms the 3rd and 5th terms from the left are Orange and \(9\).

Hence, the correct answer is Orange, 9.
