Which of the following symbols should replace (1) and (2), respectively in the given expression in order to make the expression R < H definitely true?

Statements: C > G > E; E = F; G < H 

Conclusions: I) F < G 

II) E < C 

III) C > H

Statements: E > U > V ≥ K > F; E ≤ N = L < H

Conclusions: I. L > K         II. U < H

Statements: V = W ≤ X > R ≥ O; C < O; F = X

Conclusion: I. F > R II. X > C

Statements: Q > S ≥ R = T; U < V = W < X = Y ≤ T

Conclusions:

I. R > U

II. T < U
