LSAT Conditional Logic GROUP 2 is made up of the following terms:
- Only if
- Only when
- Only where
All the words in this group follow this translation rule:
The ideas introduced by (i.e., immediately following) these words are the necessary conditions.
Let’s try it:
You may steal the Egyptian pyramids only if you achieve master ninja status.
Step 1 - Identify the logical operator
Here, it’s “only if.”
Step 2 - Identify the two main concepts (or groups, categories, events or ideas)
Here, it’s the two events “stealing the Egyptian pyramids” and “achieving master ninja status.”
Step 3 - Assign symbols to the two main concepts
Here, “SEP” for “stealing the Egyptian pyramids” and “AMNS” for “achieving master ninja status.”
Step 4 - Apply the translation rule
Here, the ideas introduced by these words are the necessary conditions.
SEP –> AMNS
Step 5 - Find the contrapositive
/AMNS –> /SEP
Step 6 - Translate back to English
If you do not achieve master ninja status, then you may not steal the Egyptian pyramids.
All done! See if you can figure these out: Group 2 Flashcards
