If 'gnr' tag zog qmp' stands for 'Seoul Olympic Organising Committee';
'hyto gnr emf' stands for 'summer Olympic games' and
'esm sdr hyto' stands for 'modern games history',
what would be the code for 'summer' ?
In the first and second statements, the common code word is 'gnr' and the common word 'Olympic'.
So, 'gnr' means 'Olympic'.
In the second and third statements, the common code is 'hyto' and the common word is 'games'.
So, 'hyto' means 'games'.
Thus, in the second statements, 'emf' means 'summer'.
