b. the president is part of the legislative branch of government.
c. a system of checks and balances increases legislative power.
d. a system of checks and balances increases presidential power.

Option A. An advantage of a presidential government is that the President is elected independently of the legislature.

Explanation:

A presidential government system is a democratic and republican system of government in which a President is chosen directly by the people and becomes the Head of State, and the leader of the Executive Branch, that is separated from the Legislative Branch. An advantage of a presidential government system is that the President is elected independently of the legislature, and by being elected directly by the voters, it gives the President a more legitimated and stable power. Also this means that the President is chosen for a specific and determined term, which does not occur with the figure of a Prime Minister, for example. All of these facts make the Presidential system a more stable and direct way of government.

polling is a process and the outcome is not involved in the process itself.

the outcome, which is an unfavorable rating for a particular candidate is not affected by the mechanical process of polling.

it rather depends on the number of people voting in favor of the candidate.

this is an outcome of people's preferences.
