Randomly methylated P-cyclodextrin RAMEB

We begin with an excerpt from Environmental Science Technology (excerpt 4B). In a combined R D section, the authors tell us what happened when they coated different types of soil with randomly methylated P-cyclodextrins (RAMEB). Cyclodextrins are highly water-soluble, crystalline sugars their shape (referred to as toroidal) resembles a water pail without a bottom. The outer surfaces of the pail are hydrophilic (water-loving), which accounts for their solubility in water and their ability to attract water molecules. RAMEB alone adsorbs water molecules hence, the authors predicted that RAMEB-coated soils would adsorb more water than their noncoated counterparts. 

Let s begin with the excerpt on randomly methylated P-cyclodextrin (RAMEB)-enriched soils in chapter 4 (excerpt 4B). The authors use an iterative R D approach They state their first result (Rl), pertaining to clay-rich soils, and then immediately offer an interpretation (Dl) of that result. This is followed by a result and interpretation for clay-poor soils (R2D2) and a result and interpretation for medium-clay-content soils (R3D3). Thus, the result-discussion sequence is iterated three times. In each case, the discussion immediately follows the result hence, submove 1.1 (which reminds readers of the result) is not needed.
