Suppose you have read two different books on world war ii, and each book has different arguments about how the war started. which of the following would be most useful in evaluating each argument?
a. determine which author used the most persuasive language
b. determine which author wrote the longest book
c. determine which author used the most reliable sources
d. determine which author used more sources

The correct answer is - C. Determine which author used the most reliable sources.

This is extremely important when trying to find out the truth and to determine what is right, what is wrong, what is a subjective opinion, or what is objective opinion. By using the most reliable sources, the author proves that he/she is trying to portray the real picture of what happened, and not expressing theories or personal opinions about things he/she has not witnessed, or to be influenced by only one side of the war.

b) a state law could be declared illegal if it contradicted the constitution.

explanation:

the conflict of this case originated when james w. mcculloch, a cashier of the baltimore branch of the second bank of the united states that the congress had chartered in 1816, refused to pay a tax imposed by the maryland state.

in the case, the state of maryland appealed that the establishment of a second bank was unconstitutional since the constitution didn't say anything about granting that power to congress. however, the case determined that even if such right wasn't specifically stated in the constitution, it was part of the "implied powers" of the government enunciated in article i, section 8.

the case also eliminated maryland's legislation to impose taxes to a national bank, asserting that even though the states retained the power of taxation, the constitution's laws are supreme and can not be controlled by the states, therefore, if a state law contradicts the constitution, it should be declared illegal.
