Summary
The analysis of a specific LSAT question demonstrates the logical approach to solving a 'must be true' problem, focusing on the distribution of materials across centers with unique constraints.
- The question involves determining the material that must be processed by Center 2, given specific constraints on what each center can process.
- Center 3 is assigned to process glass, which imposes restrictions on the materials that Centers 1 and 2 can handle, notably that Center 2 cannot process plastic.
- Center 1 must process plastic in an extra space not available to Center 2, due to the rule that if Center 2 processes a material, Center 1 must also process it.
- The solution requires deducing that newsprint (n) must be processed by Centers 1 and 2, as eliminating it would lead to an untenable situation with the remaining materials.
- The correct answer is identified as newsprint for Center 2, with a logical explanation provided for why other materials (glass, plastic, tin, wood) cannot fulfill the 'must be true' condition.
