What do most elections for local, state, and federal offices have in common?
a. they are winner-takes-all elections.
b. they are administered by the federal government.
c. they involve electors who represent the people
d. they elect officials who represent multimember districts.

A). They are winner-takes-all elections.

The reason why answer choice "A). They are winner-takes-all elections" is the correct answer because this is what our local, state, and federal elections use to elect someone for office.

The term "winner-takes-all" pretty much means who ever wins get everything, in this case the position in office. The winner-takes-all is implemented in the election because the person that has the most votes would win, so they would take the position in office.

The U.S has been using the winner-takes-all method for many years. This allows people to choose a representative that they think would be the best in office for the city, state, or country.

For example, the U.S President election runs by the "winner-takes-all" method because which ever candidate has the most electoral votes wins, or they just need to hit the 270 electoral votes to win. This is how "winner-takes-all" works in the elections.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.        

rain should be the answer.
