LSAT 152 | Section 4 | Logical Reasoning: Q20

LR Question 20 Explanation

QUESTION TEXT: Coming up with secure passwords for confidential computer files is difficult …

QUESTION TYPE: Must Be True

FACTS:

• People like simple passwords, but they’re easy to guess.
• Random passwords are hard to guess, but people forget them. This brings other cons:
• People use IT’s time by needing help
• People write them down, which is the biggest security threat

ANALYSIS: Simple passwords and random passwords both have pros and cons.

But the random passwords are actually worse, even if they’re harder to guess. Since people write them down, this is the biggest security threat.

___________

1. Writing passwords down is risky, but the stimulus never states a “should” rule.
2. This isn’t guaranteed. Forgotten passwords use up time, but it never says it’s expensive. We can presume it is so, but it doesn’t have to be true.
3. CORRECT. Since very hard-to-remember passwords that get written down pose the biggest threat, passwords that are easy to guess must pose less of a threat than those.
4. It’s actually the opposite. They pose the greatest threat.
5. This isn’t true. Maybe a middle ground is the best, where they’re not easy to guess but also not so hard that you’re forgetting it.
