This is a Method of Reasoning Type.
For this type of question, it asks you to figure out the abstract reasoning behind specific information given, so it is crucial that you identify the structure of a stimulus. While this is similar to Must Be True question because you can always refer back to the stimulus to verify your answer, a difference is that specific text from the stimulus will be represented in abstract terms. Identifying them is the key to this type of question.
Now, here is the core:
Garbage usually gets collected on Wednesday and a collector is extremely reliable + Monday was a holiday
+ When Monday is a holiday, garbage gets collected one later day.
==>
Not be collected until Thursday.
@ The argument provides a general rule: Garbage is collected in Wednesday usually. And then provides another applicable rule: when a public holiday falls on Monday, garbage collection gets delayed by one day. Next, it gives you a specific situation: This Monday was a public holiday. Applying give rules to a given situation, we have the conclusion: garbage won't get picked up until Thursday. What we need to find from answer choices are those abstract terms describing this structure of the argument.
Let's get into the Answer Choices.
A) We are not treating any irrelevant evidence. All provided rules are relevant.
B) We are not ruling out anything. If anything, we are applying additional rule.
C) This is what we have discussed above. Information with application is what happens when there is a holiday on Monday. Specific case is that this week there is a holiday on Monday. This describes what is happening in a stimulus in general terms.
D) We are not generalizing. We are rather applying a general rule to a specific case.
E) Extreme language of “inevitable.” Rule-Application is not something inevitable.
