PrepTest 79, Game 4, Question 19
Summary
The content provides a detailed walkthrough on solving a GRE question focused on identifying the initial computer in a virus chain using process of elimination and specific rules.
- Rule 3 eliminates R and S as they cannot initiate the virus chain, needing to receive the virus from another computer within the network.
- Rules 4 and 5 further narrow down the possibilities, eliminating Q and P as they also must receive the virus from specific computers.
- Through process of elimination, T is identified as the only computer that could be the origin of the virus chain.
- A hypothetical scenario is constructed to demonstrate how T could indeed be the first, satisfying all given rules and successfully infecting the other computers.
