LR Question 16 Explanation

QUESTION TEXT: Computer operating system software has become increasingly …

QUESTION TYPE: Must Be True

CONCLUSION: Businesses should implement variations in their operating system software.

REASONING: Doing so would prevent widespread damage from viruses without sacrificing compatibility between computers.

ANALYSIS: We’re looking for something that logically flows from the information in the stimulus. Nothing that is speculative, overstated, or introduces new assumptions.

A strong inference might reflect the benefit of introducing variation, or the risk of full standardization.

___________

1. We’re told uniform systems are vulnerable, not that data loss is guaranteed. This assumes an outcome the stimulus only says is possible.
2. The stimulus talks about access to multiple computers via standardization, not about total destruction on a single machine.
3. CORRECT. This matches. The passage says variation can “virtually eliminate” system-wide access, which implies much better protection, but not absolute or perfect protection.
4. The stimulus is about linked systems and the risks of uniform software. It doesn’t say anything about unlinked systems being unprotectable.
5. The whole point of the argument is that variations make unauthorized access harder, not easier. This is the exact opposite of the stimulus.
