Answer:
Archival
Explanation:
Archival research is research that involves primary sources held in an archive, a library of special collections which include manuscripts, documents, records, objects, etc. Therefore it is a collection of information from the sources that already exists. What makes it distinctive from empirical research is that unlike empirical research in which hypothesis are made before the collection of data, here we search and analyze data which is already collected in the past.
Answer:
Using biomass as an alternative energy source compared to fossil fuels has several advantages and disadvantages. The suitability of biomass as an alternative depends on various factors, including the type of biomass, its production methods, and the specific context in which it is used. Here's a comparison of the two:
Explanation:
Advantages of Biomass:
Renewable Resource: Biomass is considered renewable because it can be replenished through sustainable practices. Unlike fossil fuels, which are finite resources, biomass can be continuously produced.
Reduced Greenhouse Gas Emissions: When biomass is used for energy, it can be carbon-neutral or even carbon-negative. This is because the carbon dioxide released during combustion is offset by the carbon dioxide absorbed by plants during their growth. As a result, biomass can help mitigate climate change.
Local Energy Production: Biomass can be produced locally, reducing the dependence on imported fossil fuels and providing economic opportunities in rural areas.
Waste Utilization: Biomass energy can be derived from agricultural residues, forestry waste, and even municipal solid waste. This can help reduce waste disposal problems and costs.
Energy Security: Biomass can enhance energy security by diversifying energy sources and reducing reliance on fossil fuels, which can be subject to geopolitical tensions and supply disruptions.
Disadvantages of Biomass:
Resource Intensive: Producing biomass on a large scale can be resource-intensive. It may require significant amounts of land, water, and energy for cultivation, harvesting, and processing.
Emissions and Air Quality: The combustion of some types of biomass can release pollutants and particulate matter, which can have negative impacts on air quality and human health if not properly controlled.
Land Use Competition: There is often competition for land between food production and biomass cultivation. The large-scale cultivation of biomass for energy can lead to concerns about food security and deforestation.
Limited Energy Density: Biomass generally has a lower energy density compared to fossil fuels. This means that more biomass is required to produce the same amount of energy, which can pose logistical challenges for transportation and storage.
Seasonal Variability: Biomass availability can be seasonal, depending on the type of biomass and geographic location. This can create challenges in ensuring a consistent energy supply.
Technology and Infrastructure: Biomass energy may require specialized technologies and infrastructure for collection, transportation, and conversion, which can be costly to implement.
Comparison to Fossil Fuels:
Compared to fossil fuels, biomass has the advantage of being a renewable resource with lower net greenhouse gas emissions. However, it also has limitations in terms of resource availability, energy density, and environmental impacts. Fossil fuels, on the other hand, have higher energy density and a well-established infrastructure but come with significant environmental and climate-related drawbacks, including carbon emissions and air pollution.
In many cases, a transition to biomass as an alternative energy source is seen as a step towards a more sustainable and environmentally friendly energy system. However, the specific advantages and disadvantages can vary depending on the type of biomass and the methods used for its production and conversion. Additionally, for a comprehensive assessment, factors such as land use, water use, and local environmental conditions must be taken into account when evaluating the sustainability of biomass as an alternative energy source.

Explanation:
Feudal Japanese and European societies were built on a system of hereditary classes. ... In both feudal Japan and Europe, constant warfare made warriors the most important class. Called knights in Europe and samurai in Japan, the warriors served local lords. In both cases, the warriors were bound by a code of ethics.

Answer:
In 1897, Theodore Roosevelt was appointed by President William McKinley, as Assistant Secretary of the Navy.
Explanation:
Theodore Roosevelt, who later also became President of the United States, was known for his intense desire and his belief, in the need for his country to prepare itself for possible future wars, especially with Spain, given the growing interests, and the increasingly influential role, that the United States was playing in the world arena. Serving only for a year as Assistant Secretary, Roosevelt proved vital for the renewal and empowerment of the Navy and its forces, especially technology-wise, and he believed strongly that the United States needed to become involved in a war to prove its prowess, its power and solidify its position in the world. He also became involved with great strategists which proved vital when the Spanish-American War erupted. Theodore Roosevelt himself became a hero of this war.
