Can you help me understand this Geography question?

Use Soil 5 (last page) and determine the loading rate for each soil horizon. Note that the abbreviations used for texture class in the state loading rate chart are as follows: c = clay si = silt s = sand l = loam examples: ls = loamy sand; sicl = silty clay loam; scl = sandy clay loam Report your answer as the row and column AND the numerical loading rate. I did the Ap horizon for you in the following example. You will type the exact column-row answer in Blackboard. For example B7 or C3 or … 7B or 3C are incorrect. Letter first, number second is correct. (I just copied the Ap horizon from soil 5 here so you can see how I answered this. You do not need to do that, just flip to Soil 5 and determine the loading rate for each horizon). Ap–0 to 15 cm; 10YR 3/2 silt loam; weak fine granular structure; friable; few very fine roots; abrupt smooth boundary. (The intro paragraph says the soil formed in loess over outwash so this horizon is in loess). We go to the granular columns (B to J) and find loess (B to E) on the state loading rate chart. The soil has weak granular structure, we find those columns (B & C). The soil is friable, we find that column (B). We end up in column B. Now we find the row. The texture class is silt loam (row 5). Our answer is B5, 0.69 gal/ft2 /day. On Blackboard you would type exactly B5 as the correct answer. 5B is the wrong answer.
