Answer:
A vassal needed economic resources to equip the cavalry he was bound to contribute to his lord to fight his frequent wars. Such resources, in the absence of a money economy, came only from land and its associated assets, which included peasants as well as wood and water.
Russian version:
Вассалу нужны были экономические ресурсы, чтобы вооружить кавалерию, которую он должен был предоставить своему господину для ведения частых войн. Такие ресурсы, в отсутствие денежной экономики, поступали только из земли и связанных с ней активов, которые включали крестьян, а также древесину и воду.

Well, has a primary source, it’s probably A. person
I'm not sure if you made a typo or not but in the current context I can only see negligible being relevant.
Here's for one of them:
Type: Nuclear
Extraction: Uranium (the fuel for nuclear energy) is typically mined using open pit or sub-surface mining. Australia, Canada, Kazakhstan are where the world's largest deposits are.
Benefits: Low cost (if you don't count building the power plant), reliable (unlike wind & solar energy which comes and goes, nuclear is readily available), no carbon emissions, produce more energy than coal power plants (most popular energy source), no air pollutants emitted (all other nonrenewable sources, aka. coal, oil, and natural gas, release harmful air pollutants)
Risks to environment: Radioactive wastes require to be safely secured away for thousands of years before they can reach safe levels, nuclear accidents can happen, mining uranium cause land disturbance, thermal pollution in nearby bodies of water or wherever cooling water is released (this can lead to dissolved oxygen levels decreasing in that body of water which can suffocate aquatic life)
Other info: Nuclear energy makes up 10% of the world's energy consumption.
