A Historian would look for a primary source (option d. ) - the definition of a primary source is that it was written at the time of the event, and not later (this is the secondary choice).
<span>ohn Renshaw has just returned from Florida where he assassinated the president of a toy company. Renshaw picks up a package on his way to his apartment and carefully opens it once alone. The package is from the same toy company his victim owned and contains a set of toy soldiers, complete with tanks, helicopters, and missiles. The package begins to move on its own and releases its contents, which are animated. Suddenly Renshaw realizes he is under attack by tiny soldiers. The bullets they are firing are minuscule, but draw blood just the same. Renshaw cannot believe what is happening at first, but then begins to fight the soldiers. Renshaw cannot stop them all at once, so he is forced to seek refuge in the bathroom.</span>
Response:
Technologies and arms are optimistic, while pathogens are the negative influence of Europeans on America's future.
Explanation of:
The positive influence of Europeans on the future of the Americas was that they introduced technology, weapons, cattle, plants, etc. to America. They also also brought Christianity to the people of America. The detrimental effect of Europeans was the introduction of deadly diseases such as smallpox, syphilis and measles, etc., which destroyed a huge population of America due to lack of defense mechanisms, since these diseases were foreign to them.
