QUESTION TEXT: Most apartments on the upper floors of The Vista Arms…
QUESTION TYPE: Sufficient Assumption
CONCLUSION: At least one studio apartment in the building has scenic views.
REASONING: Most apartments on the upper floors of the building have scenic views.
ANALYSIS: We’d need to know that most apartments on the upper floors of the building are studio apartments.
You can make a logical deduction with two ‘most’ statements. It’s the least well known deduction on the LSAT, and it’s not very intuitive. If two ‘most’ statements refer to the same thing, you can combine them to get a ‘some’ statement. Here’s an example:
‘I work most days of the workweek’
‘You work most days of the workweek’
There are five days in the workweek, and we each work three. That means we overlap for at least one day. So:
‘We work together on some days of the workweek’
So if:
‘Most upper floor apartments have a great view.’
‘Most upper floor apartments are studios.’
Then some studio apartments have great views. Memorize this most + most ➞ some deduction, as it’s usually tested once every 1-2 LSATs.
___________
- This doesn’t tell us anything about studio apartments.
- This doesn’t tell us whether there are any studio apartments in the building.
- This could mean the studios are all on the lower floors and none have scenic views.
- This doesn’t tell us if there are studio apartments in the building.
- CORRECT. See the explanation above.
