LR Question 12 Explanation
QUESTION TEXT: Policy: The factory’s safety inspector should not…
QUESTION TYPE: Principle – Application
PRINCIPLE:
- Approve ➞ Used elsewhere OR increase safety
Increase SafetyANDUsed elsewhere➞Approve
APPLICATION: The inspector shouldn’t approve the new welding process. We can’t prove the process increases safety.
ANALYSIS: There were two conditions for rejecting a new process:
- Can’t show the process increases safety.
- The process hasn’t been used elsewhere for a year.
The application already shows the first reason. To prove the judgement correct, we just need to add the second reason.
___________
- Problems weren’t mentioned. Most complex processes will have some problems.
Stick to the items in the principle. If something isn’t a sufficient or necessary condition listed in the principle, it’s irrelevant. - CORRECT. This is the other sufficient condition for rejecting a process.
- So? The condition is whether we can prove the new process safer. If the existing processes are not safer, that still could mean they are as safe. That would therefore be grounds for rejecting the new process.
- This doesn’t tell us whether the new process has been used elsewhere. That’s the only important question.
- This doesn’t tell us anything. Was the process used in the other factory for more than a year? Was is safe?
We need a “no” to one of those questions for this to be the correct answer.

In the question it mentions it has “been used SAFELY for more than a year at another factory”. I chose A because it says that it a new process has “had several problems associated with the process”, thus I deduced it was not used safely
(A) says that the factory where the process was first introduced has experienced problems with the process. That doesn’t mean that the process wasn’t used safely for a year at a factory that wasn’t the one where it was first introduced. Our conditional chain is:
Policy: Approved –> Used elsewhere or increase safety
~used elsewhere and ~increase safety –> ~approved
(A) doesn’t let us say for certain that it wasn’t used safely elsewhere, so it doesn’t justify the application of the policy.
