Which of the following best summarizes the lewis and clark expedition?

it explored the louisiana territory for a year before harsh weather forced it to return to the east.
it lasted six months and laid the groundwork for settlement along the mississippi river.
it covered about eight thousand miles, mapping the louisiana territory and strengthening us claims to oregon.
it covered about eight thousand miles in its search for a northwest passage, which it eventually discovered.

ok from the research i have gathered i can at least say that summary 1, 2, and 4 are wrong. this is because the lewis and clark expedition lasted for like two years. not six months nor just 1 year. they also explored the western side of america to get a better look over of what  the western side looked like. so leaving the last option left, the correct answer that i can see is summary 3. i hope this helped katiebutt62.

the section of the chart that represents a point at which a bill needs approval from a majority of people in both chambers to advance is j, as this is the only section before the bill becomes law which has both rows (symbolizing the chambers) converging into one, meaning that the two parts of the congress have to approve of it before it can march on with the process.

i believe it would influence their own way of understanding things. it shall be a foundation where they can draw or start an argument.   historians are also  scientists that  have their tools of analysis and expertise to unlock a variety of difficulties such as relationships of man, origin, politics, economy, and culture. based on facts and understanding on these areas, they may shade light to extract ideas and develop options to validate a hypothesis or debunk it.
