Which conclusion do u. s attitudes toward the panama canal during the 20th century support?

The correct answer would be : C. People's point of view can change to suit changes in historical context
The conclusion that U.S attitudes toward panama canal during the 20th century support the opinion that people's point of view can change depending on the historical context

hope this helps

People's point of view can change to suit changes in historical context.

Allow me to add some explanation about historical context and how that works.

When the Panama Canal was built in the early 1900s, the historical and political context was one of imperialism. President Theodore Roosevelt of the United States used military pressure and warships to force Columbia to recognize Panama's independence, and then arranged with Panama to cede a strip of land to the United States (for $10 million) so that the US could build the canal and control the canal zone for commercial purposes.

By the late 20th century, the historical and political context was much different, and imperialistic control of overseas territories was no longer in vogue.  In 1977, US President Jimmy Carter signed a treaty with Panama which agreed to give over control of the canal to Panama by the end of the century, with transfer of control taking place on December 31, 1999.   

Part of the reason for willingness to make that transfer was that the Panama Canal had become expensive for the United States to maintain and operate -- so that part of the historical context plays in also.  Since Panama took over the canal, they have actually done very well financially with it.  You could check out a good book on the subject, The Big Ditch, by Noel Maurer and Carlos Yu, published by Princeton University Press in 2010.

d

step-by-step explanation:

an inequality is an expression which means more than one number is a solution. we graph the solutions on a number line to show all possible values. we graph using circles and arrows.

equal to and less/greater than are graphed with filled in circles on the value.only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.we draw an arrow the direction the solutions satisfy the inequality. generally this is the direction the inequality itself points.

this is a filled in circle on -2 so this is . this means only answers c and d are options.

answer d points to the right.
