question:
Which category contains a 2 year old tree?, Context: To accurately map the Amazon's biomass and subsequent carbon related emissions, the classification of tree growth stages within different parts of the forest is crucial. In 2006 Tatiana Kuplich organized the trees of the Amazon into four categories: (1) mature forest, (2) regenerating forest [less than three years], (3) regenerating forest [between three and five years of regrowth], and (4) regenerating forest [eleven to eighteen years of continued development]. The researcher used a combination of Synthetic aperture radar (SAR) and Thematic Mapper (TM) to accurately place the different portions of the Amazon into one of the four classifications.

question:
Who thought that laws based on the Constitution are to be interpreted?, Context: Scholars continue to debate whether the U.S. Constitution adopted a particular interpretation of the "rule of law," and if so, which one. For example, John Harrison asserts that the word "law" in the Constitution is simply defined as that which is legally binding, rather than being "defined by formal or substantive criteria," and therefore judges do not have discretion to decide that laws fail to satisfy such unwritten and vague criteria. Law Professor Frederick Mark Gedicks disagrees, writing that Cicero, Augustine, Thomas Aquinas, and the framers of the U.S. Constitution believed that an unjust law was not really a law at all.
answer:
Gedicks
