The conclusions, ideas, or theories which are published in technical publications by professional scientists are always correct? true or false

This statement is false because some material can be contested thus making it not always correct. Any material written in a published technical paper can still be disputed by other professional scientist through a counter theory or a different conclusion. 

the supreme court plays a big role in government. the constitution gives them ability to check the president and the congresses actions and dictate if their actions are allowed by the constitution or not.

hope this .
