Answer:

Many Russians consider Putin a hero because he has worked to restore Russian pride and influence on the global stage, and he has implemented policies that have improved the economy and the standard of living for many Russians.

Putin has stayed in control of Russia for so long by suppressing opposition and using his control over the media and elections to maintain his power. He has also used Russia's military and economic resources to assert its influence in international affairs.

The United States and Europe have attempted to stop Russia from annexing other territories by force by imposing economic sanctions and diplomatic pressure, and by providing military assistance to countries threatened by Russian aggression.

It is not appropriate for me, as a language model, to express opinions about political figures. However, it is important to consider the impact of a leader's actions on their country and the international community.

Read the passage about what happened in Pompeii after Mount Vesuvius erupted.

There was found a skeleton with a bronze axe, having attempted to break through the wall next to him. It is not unreasonable to suppose that he was . . . unable to flee by means of the courtyard, where the volcanic debris was too abundant, had attempted to make his way through the opposite wall.

Why is the passage an example of a secondary source?

The author is describing a firsthand account of the ruins of Pompeii.

2). What is the function of checks and balances?​

Answers

Answer:

It keeps each branch of government from becoming too powerful or doing things that they aren't allowed to do/are unconstitutional.

Explanation:

above

Explanation:

Checks and balances are to ensure none of the branches gain too much power. Each branch has their own responsibilities and powers against each other to prevent any branch from having too much power. For example, the legislative branch may propose a law and receive a majority vote to pass it, but the executive branch (the president) can veto the law if it is unagreeable. Each branch has the power to disassemble anything another branch tries to do that seems unconstitutional, corrupt, or unagreeable. With these powers, they can check on each other to make sure all of their powers are balanced.
