Logical reasoning PrepTest 155 · Section 4 · Question 7

Incorrect. If this answer stated they could be made as secure as the other options, it might strengthen the argument. However, as written, it doesn't guarantee that passwords are here to stay, as it doesn't talk about expense.

Incorrect. This answer doesn't connect to the conclusion about widespread adoption, so it can't be sufficient.

Incorrect. This answer is about the beliefs of the computer security experts, which aren't established to be relevant to the actual adoption of security measures.

Correct. Argument or Facts:
Argument

Valid or Flawed:
Flawed

Question Type:
Strengthen with Sufficient Premise

Stimulus Summary:
Non-password security measures are more expensive.
Non-passwords replace passwords → Widely adopted
Therefore, non-passwords won't replace passwords.

Answer Anticipation:
The conclusion matches with the contrapositive of the conditional statement:
Not widely adopted → Non-passwords won't replace passwords.
The premises don't establish that non-passwords won't be widely adopted, though—just that they're more expensive. So the correct answer will connect that expense with not being widely adopted.

Key Takeaway:
Strengthen with Sufficient Premise questions are frequently about connecting an idea from the premise to a new idea in the conclusion. Conditional statements are also common, so be on the lookout for them, as well!

Incorrect. While this answer choice is in the world of our anticipation, it doesn't establish when these options will develop, so it doesn't connect to the conclusion about the timeline for this replacement happening.
