not sure if this helps but I hope it does
sorry its so long
To date erosion scientists have failed to address — or have addressed inadequately — some of the ‘big questions’ of our discipline. For example, where is erosion occurring? Why is it happening, and who is to blame? How serious is it? Who does it affect? What should be the response? Can we prevent it? What are the costs of erosion? Our inability or reluctance to answer such questions damages our credibility and is based on weaknesses in commonly-used approaches and the spatial and temporal scales at which much research is carried out. We have difficulty in the recognition, description and quantification of erosion, and limited information on the magnitude and frequency of events that cause erosion. In particular there has been a neglect of extreme events which are known to contribute substantially to total erosion. The inadequacy and frequent misuse of existing data leaves us open to the charge of exaggeration of the erosion problem (a la Lomborg).
Models need to be developed for many purposes and at many scales. Existing models have proved to be of limited value, in the real as opposed to the academic world, both because of problems with the reliability of their results, and difficulties (with associated costs) of acquiring suitable data. However, there are some positive signs: models are now being developed for purposes including addressing questions of off-site impacts and land-use policy. Cheap, reliable and technically simple methods of erosion assessment at the field scale are needed. At the global scale, an up-date of GLASOD based on a scientific approach is urgent so that we are at least able to identify erosion ‘hotspots’.
In terms of explanation of erosion, the greatest need is for a full recognition of the importance of socio-economic drivers. The accession of new countries to the EU with different economic and land-use histories emphasises this need. Too often we have left people, especially the farmers, out of the picture. Our approach could be characterised as ‘data-rich and people-poor’.

Answer: She must study even if she has no interest in being a performer or composer.
Explanation:
If Gertrude wants to work in an area related to music because it is one of her great interests, she must study to know what is involved in the world of music. Many people have the misconception that studying music is only related to being a singer or songwriter, but in reality, it is a much more complex process. Universities offer music as a career and there are specialties where the person can decide in which area of music they want to focus on.
There are people who take the path of being singers or composers and others decide to focus on the field of logistics and management. Music companies need people who not only know about music but how to keep the business, make contracts and keep everything in order.
The world of music goes beyond simply being in an environment where sounds, melodies, and songs are heard, there are logistics and processes that lead the musical industries that many studies entail.
Gertrude must carry out studies in the area of music not only for the purpose of interest, but having good academic preparation will serve to continue growing in this area. People prepared both in theory and in practice are more likely to grow at work.
Gertrude should not see studying music as simply the purpose of being a performer or composer, music is a career and many people who are behind the scenes are trained people, with studies in the area of music.
