Answer:  The War Powers Resolution

Detail:

Passed in 1973 over the veto of President Richard Nixon, the War Powers Resolution (its official name) blocks presidents from continuing the pursuance of a war without Congress's approval.  This was a way of curtailing the authority of presidents to increase involvement in the war, which had begun with the Gulf of Tonkin Resolution during the Johnson presidency.

The War Powers Resolution requires the President of the United States to notify Congress within 48 hours of committing armed forces to any military action. Armed forces cannot remain deployed for more than 60 days (plus a 30-day withdrawal period), unless Congress authorizes the use of military force or enacts a declaration of war.

In practice, since its passage, the War Powers Resolution has at times   been sidestepped by presidents.  The US Constitution leaves some tension in place between the legislative and executive branch when it comes to the country's involvement in war.  Article I of the Constitution gives Congress the power to declare war.  But Article II names the President the Commander-in-Chief, and presidents frequently have understood that role as containing the authority to deploy US forces without first getting congressional approval.  The War Powers Resolution has been an ongoing point of controversy, as US forces have been sent into all sorts of conflict zones in the 21st century without formal declarations of war.

gogolik [260]

Answer:

D. most middle school children believe that those who strive to impress a teacher do not have the goal of achieving popularity.

Explanation:

A recent study by psychologists found that the main goal of most middle school students is to be viewed as popular by their classmates. The psychologists also found that the students who seek to be popular will only take as friends other students who share the goal of achieving popularity. Therefore, the psychologists argued, any middle school students who strive to impress their teachers will not make friends with most of their classmates.

The argument put forth by the psychologists assumes that most middle school children believe that those who strive to impress a teacher do not have the goal of achieving popularity.
