1.In federalism, authority is divided between two levels of government, the national, and state government, but their power is derived from the people. So, in this system of government, the people choose their representatives in governmental positions on both levels of the government to act on their behalf and protect their ideas and interest, and the citizens do so by voting. In the unitary system, the citizens have no role since the power in all centralized in the national government. The citizens have no representation as every decision is made by the national government, so they have little to no say in law making, or the running of the country. In the confederation system, citizens also have power and have more role because power is centralized in the states. The states have more power in confederate system of government, so when the citizens elect its officials, their interest are well protected because the national government cannot interfere.

2.  Division of power is how authority are divided among the different levels of government, and its purpose is to make sure that one part of government does not become too powerful, and that they can each check and balance each other. The constitution created this division by giving each level of government their different duties, the federal government has its powers, and duties like declaring war, and the state government has its own powers, and duties like regulating intrastate commence.

3. During Covid-19, the federal government directed the states on what to do from time to time, like reopening parts of the economy, the states had to abide by it, but this was an issue for the then NY state Governor Cuomo,  because the federal government was asking the states to do things but provided no support. The Governor reiterated his call for the federal government to provide unrestricted funding to the states to help stabilize the economy and allow the states to perform reopening functions. The federal government has passed three bills to address this crisis, including the federal CARES Act, all of which contained zero funding to offset drastic state revenue shortfalls, but still the federal government put the responsibility of reopening the economy on the states.
