Correct Answer: in front of the house
Explanation
Introduction / Context:This sequencing puzzle tracks personnel swaps around a house. You must follow two consecutive position exchanges to determine one worker’s final location.
Given Data / Assumptions:
- Initial positions: Michael = front; Ross = back; Jed = north; Shawn = south.
- Swap 1: Michael ↔ Jed.
- Swap 2: Jed ↔ Shawn (using Jed’s new position from Swap 1).
- No other changes occur.
Concept / Approach:Apply the swaps strictly in order, updating positions after each. Keep a simple table or running list so that you do not revert Jed to his original position before the second swap.
Step-by-Step Solution:
Start: M(front), R(back), J(north), S(south).After Swap 1 (M ↔ J): M(north), J(front), R(back), S(south).After Swap 2 (J ↔ S): J(south), S(front), M(north), R(back).Therefore, Shawn ends up at the front of the house.Verification / Alternative check:
Reverse the process mentally: If Shawn is at front at the end, then just before Swap 2 he must have been at south, and Jed at front—consistent with Swap 1’s aftermath.Why Other Options Are Wrong:
North/Back/South do not match the final tracked position for Shawn after both swaps.“Roof” is an irrelevant distractor not supported by the scenario.Common Pitfalls:
Accidentally applying the second swap to Jed’s original location instead of his post–Swap 1 location.Final Answer:in front of the house
