21. D
    The assumption that long-range warning or cooling trends are more damaging to grain production if they are accompanied by changes in rainfall patterns than if they are not is based on the promise in the statement above, stating that more optimistic reports point out that even if drifts in average temperature do occur we should expect little change in grain production because there is little evidence that changes in rainfall patterns will occur.

22. D
    Choices A, B, C & E cannot be true. From the proposition that type O blood is essential for emergencies where there is no time for determining the blood type of victims because type O blood can be used for everyone; it is clear that any decision to give blood of any type other than O needs to be based on the knowledge of the recipients’ blood type.

23. A
    B, C, D & E cannot be inferred from the above statements. But it can be inferred that the fire department did not arrive at the house yesterday.

24. D
    The other choices are not relevant and weak. Whereas choice D strengthens the claim in the above statements.

25. B
    In the above statement the proposition capital punishment deters murders only during weeks when well-publicized executions take place is a universal proposition. The statement in choice B which stands under the above universal proposition is also therefore true.
