Direction: Read the following information carefully and answer the questions that follow:
In a certain coding system,
P & Q means P is not greater than Q,
P % Q means P neither smaller than nor greater than Q.
P @ Q means P is neither smaller nor equal to Q,
P $ Q means P is not smaller than Q
Based on the information provided above, answer the following questions.
Statements: L @ T, A % O, T $ D, A @ L
Conclusions:
I. T % O
II. L @ D
According to the information given,

Given statement: L @ T, A % O, T $ D, A @ L
After converting: L > T, A = O, T ≥ D, A > L
After combining: O = A > L > T ≥ D
Conclusions:
I. T % O ⇒ T = O → false (as O = A > L > T → O > T)
II. L @ D ⇒ L > D → true (as L > T ≥ D → L > D)
Hence only conclusion II follows.
