which conclusion do u.s. attitudes toward the panama canal during the 20th century support?\na. biases prevent most people from participating in a changing historical context.\nb. peoples points of view can change to suit changes in historical context.\nc. contextualization of a historical event should not be changed once it has been made.\nd. historical context can only be determined long after an event has passed.

Answer

Brief Explanations:

In the early 20th century, the U.S. saw the Panama Canal as a strategic asset for its naval and commercial interests. It was built and controlled by the U.S. with a focus on its own power projection.
Later, as the geopolitical context changed (e.g., anti - colonial movements, changing international relations), the U.S. attitude shifted. In 1977, the Torrijos - Carter Treaties were signed, which provided for the transfer of the canal to Panama by 1999. This shows that the U.S. view of the canal (from full - control for its own benefit to a more cooperative and context - responsive approach) changed as the historical context (such as the rise of Panamanian nationalism and new international norms) changed.
Option A: There is no indication in the U.S. attitude change towards the canal that biases prevented people from participating. The U.S. was very much an active participant, just with a changing attitude.
Option C: Contextualization of historical events (like the significance of the Panama Canal) does change as new historical contexts emerge. The U.S. re - evaluated its position based on new contexts.
Option D: The U.S. was able to re - evaluate its attitude towards the canal while the events (like its operation and the transfer process) were still unfolding in the 20th century, not long after the canal was built.

Answer:

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