Question

If in the third step, "9" interchanges its position with "14" and "Orange" also interchanges its position with "Rotator", then which element will be to the immediate right of "18"?

• A. Radar
• B. 14
• C. Union
• D. Rotator

Hint:

When multiple swaps are specified, carry them out on a clean copy of the line and then read off the requested neighbor directly.

Answer 1

The Correct Option is B

Step 1: Write the sequence at Step 3.
Step 3 (before the stated swaps) is: \[ \text{Wow},\ 3,\ \text{Orange},\ 18,\ \text{Radar},\ 9,\ \text{Rotator},\ 14,\ \text{Unit},\ 9,\ 11. \] Step 2: Perform the two interchanges.
(i) Interchange the entries \(\,9\,\) and \(14\) \(\Rightarrow\) the \(14\) moves next to \(18\).
(ii) Interchange \(\text{Orange}\) and \(\text{Rotator}\) (this does not change the neighbor of \(18\)).
Step 3: Read the immediate right of \(18\).
After the swaps, the element \emph{immediately to the right of \(18\)} is \[ \boxed{14}. \]
