What is the firing order of a six stroke I.C.

Statements:

E ≤ A > J ≥ L; Y > J < D

Conclusions:

I. D > L

II. A > L

Statements: S = T, U < L, V ≥ S, T ≤ U

Conclusion:

I. T ≤ V

II. L > T

Statements:

A ≥ Z > B ≥ Y; C > B ≥ W

Conclusion:

I. A > W

II. C > Y

Statements: Y ≥ Q ≥ P = T; T ≤ H < O; O > I

Conclusions:

I. P ≥ O

II. I > P

III. T < Y

Statements: B > C; D > E = F < G ≥ H; C > I = D

Conclusions:

I. B < E

II. G > E

III. I < B

Statements:  M = R ≥ S , N = O > Q, Q > W = A < S

Conclusions :

I. N ≥ S

II. W > R

III. O ≤ S
