Read the following excerpt from a US court opinion:
```
original sentence hearing went no further than “at least 1.5 kilograms.” If so, that finding is not specific enough to support any conclusion about whether Amendment 750 lowered Hamilton’s base offense level, because “at least 1.5 kilograms” is equally consist tent with a finding of 8.4 kilograms or more and a finding of less than 8.4 kilograms.

C. holding the findings of fact required to support an alimony award are sufficient if findings of fact have been made on the ultimate facts at issue in the case and the findings of fact show the trial court properly applied the law in the case
D. holding that a reviewing court has the power to reject the findings and conclusions of the trial court where the findings are not supported by the evidence
E. holding because defendant does not argue in his brief that these findings of fact are not supported by    evidence in the record this court is bound by the trial courts findings of fact
