Answer:
laboratory observation
Explanation:
According to my research on different research methods, I can say that based on the information provided within the question the most appropriate method of study in this situation would be a laboratory observation. This is because this method is the most efficient method, mainly because it would allow for special equipment to measure the physiological changes. Another good method would have been a naturalistic observation, but since the Professor wants to measure psychological changes and not observable changes this will not suffice.

Structure in writing depends on what the objective - what the writer is trying to convey. If it is an argument, the structure will include a problem statement, supportive explanations and a conclusion. If it is a narrative, the structure can be subjective - the narration will go along with the observer throughout; or it can be chronological - a description based on time order. If it is simply writing something personal, then the structure can be flexible and free flowing.

Soil compaction occurs when soil particles are pressed
together, reducing pore space between them. Heavily compacted soils
contain few large pores and have a reduced rate of both water infiltration and
drainage from the compacted layer. Excessive soil compaction impedes
root growth and therefore limits the amount of soil explored by roots. This, in
turn, can decrease the plant's ability to take up nutrients and water. From the
standpoint of crop production, the adverse effect of soil compaction on water flow
and storage may be more serious than the direct effect of soil compaction on
root growth.
