Summary

The analysis focuses on solving a global question from PT 78, Game number 2, determining which students can be assigned to slot number 1 in 1921.

- The solution involves testing each student to see if they can fit in slot number 1, considering the constraints provided.
- R cannot be in slot number 1 as O must be immediately before it, eliminating R from the possibilities.
- L and T are also eliminated as potential candidates for slot number 1 due to the inability to fit the OR block according to the rules.
- M, O, and Y are identified as the students who can be assigned to slot number 1, making the answer choice D.
- Common mistakes likely stem from overlooking the constraints on L and T, leading to incorrect selections.
